Title: R.T.T.L. 2751
Post by: John W E on November 13, 2009, 04:14:19 pm: hi there one and all

I have begun a new build. The original idea comes from the plans drawn up by Vic Smeed which were published in The Model Maker 1958.

To begin with I had a struggle in deciding which way to build this - to keep true to his plans, or deviate from them slightly.

I had looked at Raymon's build of the Swordsman and Raymon has stayed true to the plans of a Vic Smeed build, where its a ply-wood skin build with very little flare in the top sides and no flare whatsoever incorporated in the bottom panels of the hull. Raymon has brilliantly stuck to the authenticity of the plans by building his model and it looks really good.

When I did a web search for the R.T.T.L. produced by the same plan which I have; they all have slab sides and flat bottoms, which is the way they were built back in the 1950s. Now, after studying a great deal of photographs, I could see there was a slight flare in the top sides, which is shown in some sections of the Vic Smeed plan. On the bottom panels of the hull there is no curvature in the front of the hull; but, on the photographs the bow has a very fine entry and also the chine line is similar to the Brave Borderer Class hull. So this is what I have done. I redrew the hull lines onto a sheet of plywood using photographs as references; kept the same amount of frames as Vic Smeed plans and also altered the chine line as well as the fine entry at the bow. Also, instead of using plywood I am going to double-diagonally plank the hull. For the eagle eyes you will see that I have removed the insides of the frames to keep it light. Progress so far -

How big is she?

The wife she must be about 5feet4 inch's %) but the hull is 34" long

Post by: John W E on November 15, 2009, 05:14:52 pm: couple more pics of the build so far, busy diagonally planking the sides first - the planking material is lime 10mm x 1mm thick - started off planking in the centre of the hull marking the first plank off at 45 degrees. Working 5 planks per side; at a go - so in other words glue on 5 planks portside, turn the model round glue on 5 planks starboard side and by that time the planks on the portside have dried (in theory) %) and you should be able to carry on clamping more planks on in this way....

if you look closely you will see rings on the planks - no its not its age :-) - it is caused by glue getting between the clamp face and the plank.....

Post by: howyson on November 16, 2009, 06:54:55 pm: Hi from another geordie

You are making a superb job of the hull. I restarted on my RTTL fifty years after only completing the hull. It is based on the original Vic Smeed design. I have some photos in the model boat section under Model Maker Vosper RTTL. Since I took them I have made some more progress on the superstructure but the Vic Smeed plans are limited in detail and you tend to end up guessing.

I have just had a look at your build which you have posted - I am wondering now - should I have done my model similar to yours, yours looks brilliant!!! If you have a scout around the Forum and look at Banjo's threads - he has the RTTL which is well-built as well. Banjo's is of the early version without the engine room cabin fitted. I am posting a couple of photographs which I have been working from for details etc., and these may help you. (photographs courtesy of Christian)

Nice shape to the hull you've got there :-))

Looking at her flowing lines and curves reminded me that here in Bridlington on the east coast of the UK we had similar RAF boats used for air sea rescueback in the 60's and 70's

(http://www.asrmcs-club.com/images/File0799.jpg)

The RAF kept two boats at Bridlington if my memory serves me right and there were large maintenance sheds with a slipway at the top of the harbour.

The launches were regularly hauled up the slip on huge yellow painted 4 wheeled cradles and I spent many a happy hour with my friends playing under the hull and marvelling at the flowing line and studying the huge bronze propellers :-))

RAF 1383, 1387, 1389 and 1390 were based at Bridlington in the 1960s.

1392 was the last RAF pinnacle to leave Bridlington on December 8 1980 to make way for the new air sea rescue helicopters still based at RAF leconfield near Driffield.

(http://webspace.webring.com/people/mj/johnj3/1392.jpg)

These lovely boats have been missing from the harbour scene for years now :(( but the slip and sheds still remain and are used by cobble owners to slip their boats these days

(http://www.asrmcs-club.com/images/DSC00654.jpg)

You can just see the shed doors painted blue and slipway to the far left behind the yachts in the above photo of Bridlington harbour.

I'll post photos of RAF 1383, 1387, 1389 and 1390 if I can find any on the web :-))

Thanks very much for the photos they are very helpful. In particular the winch photo is great but means I must start again. My guess from the profile on the Vic Smeed plans was way out.

I have not checked the Banjo link out yet but will do soon as possible.

I have some photos of the 2751 I found on the net but I am having problems attaching them to this post. Will hopefully overcome the problem and post them later.

Finished the first skin of the side planking and I have sanded down it down lightly to remove some of the glue marks, but, I havent finished sanding it yet.

I am now in the process of planking the bottom section of the hull, using the same sort of method working 5 x planks per side.

Just a quick update – as you can see I have finished planking the bottom section of the hull now. In the process of sanding and filling any dints or mis-alignments in the planking. Once this is complete I will begin putting the 2nd row of planking on – only this time it will be using mahogany planking – planking in the opposite direction to the first set of planks and also the planks will only be 5mm wide x 0.5mm thick (scale sized planks for this build).

Couple for questions, why double diagonal plank does this offer anything to the strength of the hull and why the two different types of wood.

Title: Re: R.T.T.L. 2751
Post by: John W E on November 22, 2009, 05:53:11 pm: Hi ya mates

One of the reasons I am double-planking this particular model is that I want to keep it relatively light, as well as strong. So, with double-planking in the different directions offers the same strength as ply-wood. Ply-wood gains its strength by having its timbers running at 90 degrees to each other. The reason for the 2 types of wood at the stage is for expense really as well as authenticity. The outer planks are going to be mahogany at 4mm x 0.5mm thick. This is roughly the scale size planking for this hull. To plank a full hull in mahogany would cost a lot more (double the price maybe) of the hull. If I so wished, I could, at this stage, do what I normally do and that is put a layer of polyester resin with tissue mat over the hull - this wouldnt make for a very strong hull though on this build, because the inner planks are not that thick - i.e.l 0.8mm thick.

When I have finished planking over the top with mahogany I am going to coat it in 3 coats of epoxy resin on the outside and 2 coats of polyester resin on the inside of the hull - this should give me a hull which is twice as light as a similar hull in fibre glass but with the same strength as fibre glass. If not stronger - I mean howway me track record - it's gotta take on a few concrete lakesides in the next season hopefully %% %% %%

Hope this answers your queries Marc and Dicky.

Post by: John W E on November 23, 2009, 07:29:23 pm: hi there

Mike thanks very much for putting that link on - that is a very interesting link with regards to double-diagonal planking :-))

I have spent a bit of time today, trying your idea Mike of assimilating the calico between the plank layers. I have abandoned the idea now, to be honest, because with it being a chined hull - I couldnt get it to stretch evenly into the concave areas of the bow; I tried using tissue and a very light cotton - but at least I tried.

Whilst on the subject of double-diagonal planking we must realise that there are several versions of this boat, which were built at several different yards. The planking arrangement therefore differs, so, not all of these may have had the horizontal stern planked.

Some vessels, or should I say 2 vessels with the E after the numbers, were the experimental vessesl and these were built with aluminium bottom and fibreglass sides. Later in their life, this was stripped off and was replaced with double diagonal planking.

The other thing to remember is that the Mk Ia 's had 3 Napier-sea-lion engines. So did the Mk Ib 's but, the Mk 2 's only had 2 main Napier-sea-lion engines. The thing that is confusing is that the 2751 there are reports saying that she is a Mk 1 with 3 Napiers and other places she is a Mk 2 with 2 Napiers - I am going to get this clarified first though.

Post by: cdsc123 on November 23, 2009, 08:29:23 pm: Hi chaps

The MKI 68ft RTTLs were the old wartime Hants & Dorset HSLs (3 x Napier sea Lion) stripped of armament and fitted with target towing winches powered by 10hp petrol Fords. The numbers fell between 2552 and 2746 inclusive. The post-war design MKIAs were a beamier design, and to start with were (under-) powered by the 3 Napier Sea Lion set up until the Rolls Royce Griffons came available. The numbers were 2747 to 2750. The subsequent five were designated MKIBs and were also built with 3 Napiers, but had slab sided aluminium superstructures with improved internal layout. These were numbered 2751 to 2755. All these boats were upgraded to MKII spec when the new engines came available. The MKIIs were built with the RR Griffons and were numbered 2756-2761, and 2767-2771. The experimental MKII was 2762E, later re-numbered 2772E and when re-planked to standard spec she became 2772. She was never 2762 because there was another RAF rescue vessel with that designation.

Title: Re: R.T.T.L. 2751
Post by: cdsc123 on November 23, 2009, 09:51:05 pm: Sorry, no. I'm not convinced the RTTLs had these though, I think the Brave Class which were a larger and faster version of the same hull design had them though. The RTTLs were famous for needing an experienced helm to prevent slamming onto one chine on re-entry after wave jumping, due as you say to the torque effect of having same handed props. The trick was to apply helm on take-off to counter the torque effect.
They did however have transom wedges retrofitted to bring the nose down, a comparison photo showing one boat with and another without can be seen here, close to the bottom of the page;
http://www.bmpt.org.uk/boat%20histories/brave%20class/page_two.htm

Post by: John W E on November 24, 2009, 07:22:22 pm: hi all

just a quick update, started on the exterior planking there are 30 mahogany planks on there - and its taken me the best part of the day to do this much....but both sides are done - I have calculated there may be 360 odd more planks to go on.....the steel tubing that you see in the foreground is what I am using to roll the planks over - to get the bend in the planks. Also, when I have put the glue on the back of the planks I use the tube similar to a rolling pin - this removes all the air bubbles from underneath - it also beds the plank in. :-))

so here goes....planking away

oh - and I have added a front view to show the flares of the bow.

Hi ya Brian this is interesting, I havent managed to find any facts to back this up yet. The only thing I can find on the web and in a few books which I have is where it mentions strengthening the starboard side chine and adding extra supports to the affected areas - logically thinking I cannot see them adding an extra layer of diagonal planking over the bottom of the hull as this would increase the weight of the vessel and dratrically decrease its performance.

I would have thought that if they were that concerned, they would have just reduced the govenor settings on the engines. I did, however, find reference to strengthening the hull at the chine on the experimental boats which had aluminium bottoms on the hull and they were prone to cracking around the chine where stress was caused, but, this was later rectified where they stripped off all of the aluminium and fibre glass and replaced it with double diagonal planking.

Post by: Perkasaman2 on November 25, 2009, 09:37:25 pm: Stengthening/adding frames after skinning x2 and final fitout would be a nightmare/uber expensive exercise (Vosper liability - design unfit for purpose i.e. 40knots?????) After the inexpensive final trim wedge solution (a la' E or S BOOTE fashion) adding a third 'stiffening' bottom layer of 15/16" must have been a hugely cheaper/getout for Vosper. The waterline on the mk11 rttl's is very interesting/revealing. Don't forget that these structural issues ocurred in only certain sea states and general governing of the throttles would have been inappropriate/unnecessary in all other sea conditions where the full monty ok.
You are not seriously intending to add an extra skin if you verify the fact :o :-)

I took this photo of 2753 when she was being broken up, you can clearly see there are 2 layers of planking despite what I have read on the subject.

The really interesting thing is the cross section of the trim wedges;

Post by: cdsc123 on November 27, 2009, 06:37:54 pm: Hi John

I suppose some must have, as lead historian T Holtham says they did in his published work (RAF Marine Craft Directory).

Perhaps 2753 slipped through that net. The thing to look for is the direction of the outer layer on the bottom, as a 3rd layer would surely have gone in a different direction to the 2nd layer. I note from recent photos that 2751's outer layer of bottom planks runs parallel to the stem, i.e. "leaning forwards", whereas 2753 had the opposite. This could mean 2753 never got the 3rd layer but 2751 was one of the boats that did (this assumption is made safer as they both came from the same builder).

Pure conjecture, but a theory nontheless.

put this into the pot for the theory.....I did a quick calculation of the weight of an extra skin made of mahogany 1/2 inch thick - using the model to scale the area required and it comes just under 1/4 of a ton in weight

now you stick that 1/4 ton on top of the total weight of the hull already and to maintain the average of 39-40 knots the power requirements - you would have to find another approx 10 horse-power per engine

...... does this make sense :-)) ah but to be on the safe side I might put a 3rd layer of skin on .....

what really surprised me were the actual trim wedges - I was visualising a lot larger wedge in depth - just goes to show it doesnt take much to trim a boat.

Post by: John W E on December 18, 2009, 07:18:49 pm: Hi there all

Just a quick update. I have finished rubbing down the outside of the hull; and removed it from the building board. As you can see, I have installed the prop shafts and the motors. The motors at the moment are only in temporarily and so I can see how they perform - they are an MTronik Vision Motor - originally I was going to use a Graupener 600E motor - and I still may go down that route.

Also, I have added the rudders and the rudder tiller arms. As yet I havent fitted up the linkage between them.

Here's a couple of pics....

Post by: John W E on December 19, 2009, 05:44:20 pm: Dicky hi ya there

The motors run nice n sweet and quiet. The problems, which I have sorted now were the:

Cheap - Ebay prop shafts >:-o which I have managed to re-bush in situ with smaller bushes which fit the propeller tube properly rather than being a rattling good fit.

Couplings - I removed the red insert and replaced it with a bit of silicon tubing and the motor can hardly be heard, whilst its running at full belt. But, as soon as the red couplings are put back - its like a bag of hammers - so that is the next job to sort out.

I have tested the model in the bath - and it empties the bath quite nicely! %% Drawing all of 12 amps per motor.

So, I think I am going to have Mr ACTion's heavy duty P94.

Through the grapevine I have heard there is a sound unit on a test bed ... it has had a brief outing ... but stilll in test. This unit, so I believe, reproduces digital sound recordings and which may be downloaded from the computer.

One of the main sounds, if required, can be a multiple Griffen engine.

Also, one may record other sounds onto this unit - but - we will have to wait and see.

I believe the code name of it may be the P100.

Just a quick update. I have near enough finished the planking of the deck and I have given it one coat of sand ‘n sealer which has been mixed 50-50 with cellulose dope. Next stage is to rub that down and I am going to stain the deck slightly darker, using a mixture of tea bags and coffee mixed up! Then I will seal it up again over the top of that with another 2 coats of sand ‘n sealer rubbed down between coats. But, as you can see from the last picture I got 2 Christmases one on the 25 and another pressie via the postman me P94 twin speed controller and mixer. The likes of you Dicky you get a complete one when you got yours from ACTion – I didn’t know they did a kit version – but I do now  .

Fast progress wor John! :o The raised engine hatch/roof and structure looks fairly straightforward to construct, however the aft winch canopy is original build and similar in style to the bridge superstructure. The winch canopy is relatively seamless/edgeless - rounded edges throughout. (Bearing in mind the winch canopy is open on it’s rearward face.) How did you construct the canopy and what materials /techniques did you use to get the streamlined/smooth shape, particularly the curved roof and maintain the curve on it‘s open edge? - (My guess is a grp moulding - am I right? ) Finally, did you use styrene strip to form the bottom edge/skirting on this canopy?

As a young CCF RAF cadet I was on an RTTL in Cyprus in 1967 or 1968 - they gave us a day out on a boat from Limassol to Paphos. I wonder if it was one of these? Probably - I suspect there weren't that many of them down there at the time....

Hi DG, the sound from the marinised griffons thru the rear quad exhausts must have been trully amazing/memorable. :o :-)

I vaguely remember being deafened towards the stern, so I spent much of the trip with my head poked out of the hatch on the foredeck. I had a camera with me, and took many pictures of the scenery, but, of course, none of the boat!

Pictures of Dodgy are usually kept well clear of the Internet, but I have found one which shows me leaning on a corner of the superstructure. The arrogant look is partly explained by the fact that the teacher supervising us was one Gordon Jones, whose father (Air Marshal Sir Edward Gordon Jones) was the C-in-C Near East command, and Administrator of the SBAs in Cyprus at the time. Unsurprisingly, the entire service contingent spoiled us rotten wherever we went...

Kenny your lifeboat is over twice the size of this thing :-)) and I am watching your build with interest too- I am looking forward to seeing how you construct your hull - I like to look at all builds on here. If you notice take Gribauval when he builds a hull for the lifeboats he uses a billings technique whereas the main deck and the keel hold the frames secure while he planks the hull. Also have a look at boatmadman when he built the trawler; used a building board but he never fastened the planks to the frames - he insulated the frames with masking tape to prevent them from sticking so he could lift the shell planking off. So, it is always nice to see how others do their hulls. Looking forward to seeing yours and Dicky's - when wor Dicky does a scratch build.

Just a quick update – been in a right turmoil for the last couple of days – whether to change the build and change the number. After a certain amount of research launch number 2755 was equipt with a 20mm gun on the back on top of the engine cabin roof and this was in 1965 when there was a little bit of unease with Indonesia. So, during the uneasy period, this particular launch was equipt with a weapon and, as far as I know, she was the only one fitted with a live firing gun. So, I am still undecided – I think I am keeping her as 2751 that is what my instincts tell me 
Done a bit more though and added some fittings.

A note for FLJ well he must have the fastest sound unit around now. The RTTL did speed trials this morning at the Lake and it covered 100 yards in 16.9 seconds - not that fast I know, but, hey RTTL wasnt built for speed - but she had all her sound effects going full blast and I suppose that isnt bad for something one didnay build for speed :-))
:-)) .

The P94 stood up well to the abuse it received; so did the sound effects and amp as they did get a bit wet! Cant be bad me thinks.

How’s you?

The transom frame is held onto the keel with a form of mortice and tenon joint

The slot in the transom is the same width as the thickness of the keel and is approx one and a half inches loing

Just sent you a personal message about the deck planking - but as far as plans for this vessel in pdf format goes - there used to be a guy on here who had the frames (I believe) in the PDF but not sure if he had the superstructure.

Sadly, I dont think I have any further information apart from a couple of photographs on my hard-drive and a couple of very small illustrations of the hull and deck - will try and download them later on. Been having a few problems lately downloading onto this site; as the files keep coming up 'not acceptable on jpeg.f whatever that may be :((

I am sure the numbering I got it from Barry's lettering.

That is awesome! That's what I think... the detail on your 2751 is outstanding and I'm ever so slightly envious of your skills & patience.

I'm quite new to this boating world and am currently building the Model slipway RTTL, which is my first attempt at a "build" (my previous 2 boats have been yachts from kits, so only basic assembly required!) and if I can get mine looking 10% as good as yours I'll be a happy man!

Any chance you can post some video of her sailing?

Kangaroo1
if you do a search of this forum and you will find DickyD did a build of the Model Slipway's RTTL - and someone else did as well. Can remember who else did the build.

Thank you for the compliments about my build and model - as yet there be no video of her sailing - but I will try and do that someday :-))

Post by: dodes on March 26, 2012, 09:43:56 pm: I was reading your comments on propulsion, the RMAS had one at Greenock in the 1960/70's as a fast courier launch. She difinetly had 2 x shaft driven by 2 x rolls royce merlin engines, she planed at 42 knots, she was called Falcon but was nicknamed the bomb on account of her being cartridge start at full throttle and what a row she made on start up. I was lucky enough to take her out for a job, r/v with a nuke sub, picking up a passenger off the subs forward diving plane.

I don't think that they were ever fitted with Merlin engines - usually RR Griffons.

Post by: John W E on March 27, 2012, 01:07:14 pm: Hi dodes
it may be possible that the boat you sailed on was powered by the sea Napier engines; as some of them had the Coffman /or the Breeze cartridge systems in to start the main engines. At the moment I cannot find reference to Merlin powered 68'RTTL' most started life with 3 Napier engines then in later life being converted to 2 Griffin motors but as they say life is not set in stone and rules are broken so they may have been one :-))(where is CHRISTIAN CD123 when you need him )

Just to bring this one up to date a little, Falcon was actually called Osprey which was later changed to Canadian Osprey on her sale. She now exists as a Diving Support Vessel and has been completely refitted/refurbished. Her twin RR Griffons have been replaced (which doesnt surprise me as spares would be almost impossible to find nowadays) with GM diesels

Her hull number in RAF days was 2770. She was the penultimate RTTL to be built for the RAF, her sister 2771 was last seen laid up in Malta after retirement from the Maltese Coastguard. Both craft were the only RTTL's to be built for the RAF by Saunders & Roe the rest being Vospers, Groves and Gutteridge or BPC.
Title: Re: R.T.T.L. 2751
Post by: Soupdragon on June 04, 2012, 04:07:02 pm: Have to say I'm much impressed with your model on 2751 :-))

I sailed on her many times when she was stationed at RAF Mountbatten in Plymouth. She was being used back in 1973/4 era as a testbed for the refurbished Sea Griffons which were rolling off the RAF's production line in Plymouth. At the time i was crew on one of her sister craft, 2757, and her crew regularly used to get detailed to take 2751 out on a test run as '51 didnt have an official crew. After the engines had been tested and approved they would be removed, inhibited and placed in storage in case they were needed for any of the RTTL's still in service both at home and abroad. At that time the Marine Branch were still operating RTTL's in Gibraltar, Malta, Cyprus and Gan in the Maldive's. In all i served on RTTL's 2751, 2752, 2753, 2754 and 2757.

Someone asked where the Larne Targets were stowed when not in use - either side of the winch house was the usual stowage. The handrail was very handing for lashing the target securely. Two were usually carried, if an extra was to be taken then it would be stowed on the starboard side of the superstructure and, yet again, secured to the handrail

Has your RTTL have a black boot line around it

Post by: John W E on May 30, 2014, 04:36:44 pm: Hi Gary

Sorry but the only pic / information I has is on page 1 of this build also if you have the Model Maker plans I believe there is a side outline drawing of the motor. These are what I worked from to recreate the winch on my model. The only person who I can think of at his present time who may have more information is Christian cdsc123 as he supplied 90% of the information which I used for this build and he may be able to help you too.

Now for the next question - how the hell do I know %% %% %% %% %% %% %% {-) {-) {-) {-) its been one of those days hahah

Nowts going right - this is the second time I have attempted posting this....

Anyway :D with my model being painted in a Mediterranean white colour scheme there is no topping but I have seen pictures of her painted with a white boot topping when she was painted with black sides. I believe this photograph is somewhere on this build. There again, the best person to answer this query with be Christian - he is a mine of information regard this craft - or any service craft come to that.

In fact its time for Christian to dive for cover - I am thinking about building another Air Sea Rescue Launch sometime in the near future. :-)) :-)) :-)) :-))

Hope this helps.
