As Mark says, it looks good, and it is YOUR choice, wasn't trying to down you in any way, just a bit worried that in tight turns, you may get self flooding.

Can't see the piccy too well but the rails should go from either side of the bow nose, full length to the back (Transom) on the bottom edge of the vertical skin. It sticks out a bit like the threshhold rail (Driprail) on a door and stops the water from sticking to the base and up the sides.

Regards Ian

Can we co-ordinate Mark

Hi Dread the twin rudders on your model are correctly shaped and very similar to those fitted on the original. How long is your model?. Please note that the hand rails fitted around the deck of the Hendon boat were H & S additions after she arrived at the museum, to enable staff to have safe access. My photo was taken in March during my visit to Hendon. Have a look on the 'Deans Marine' site at their RTR model for comparison.

Ok,chines fitted as per description,I'll take some more video today,and i'll compare the two,just to see the difference they make.

O/A length: 34.5"( measured properly this time) Beam: 9 7/8" Perkasaman. I realised that the handrails on the Hendon boat were just as a safety measure,and not fitted for duty. I don't have any inkling as to who originally built this boat or when,but the original speed control was of the wiper type.

I'm having trouble trying to upload any video's just now,every time I try,Firefox crashes out.

Dreadstar · « **Reply #29 on:** September 14, 2009, 12:48:44 am »

Ok,here's a couple of vids to start with,until I can get the rest uploaded. There is a marked improvement with the chines fitted,although,I need to reposition the bow ends of the chines.

Looking good. You will find your turning circle is a lot smaller as the boat pivots on the chine and your speed will have increased ever so slightly.

My son was taking more video's than I'd realised.

The vosper had snagged on a submerged poly-bag,that had wrapped itself around my prop.

Can anyone tell me what colour the 'mushroom top' air vents are supposed to be?

I presume your talking of the Cowl vents on rear structure and at the side of structure?

If so the only information I have found to date is they are the same grey as wheel house. If you are talking about the vents placed around the deck they are light grey (probably the same colour as the wheel house).

Dreadstar · « **Reply #35 on:** September 15, 2009, 05:43:59 pm »

Thanks for that Mark.

I re-set the chines at the bow,and added a piece of right angled brass on the leading edge of the bow,to help cut her way through the water at low speeds. I'm just back from the park,(but I forgot to take my camera with me),after testing out the mods. What a difference it's made,getting the chines angled properly,they really do throw the water well clear of the hull. The brass strip has made a difference too, allowing the boat to carve through the water,rather that building up a large bow wave. I had to change my steering servo though,as my Kyosho KT-14 transmitter wouldn't control the existing steering servo. I've now got an ACE 1015 servo on steering duty,(far more torque than is needed),but I need to be careful not to turn too tightly with it,because it has a very fast transit time. I've changed the prop to a 40mm 2-blade one,and with the GP 4300MAh packs,I'm getting almost 45 minutes run time from the one pack. Not much in the way of deck furniture to add now,just the large airvents and a dinghy now,and the cockpit to finish off. Some pics.

Please excuse the Araldite everywhere,but once the hull's been repainted,it won't be so obvious.

I knew that this boat had been around for a while,but I was quite surprised when one of the other club members told me that he had a photo of her in action in East Kilbride,back in 1976. That makes this boat at least 33 years old,if not more,depending on how close to the publication of the plans,that she was built.

I've asked him to bring the photo along on Sunday,so that I can see her.I'll try and take a photo of how she looked back then.

Dreadstar · « **Reply #37 on:** September 18, 2009, 12:51:13 pm »

Just ordered up a set of painted MTB figures along with a dinghy from George Turner,and ordered the engineroom vent cowls & davits from macsmouldings.This may be an old boat,but it's my first real scale one,and I want to get her finished off as near as possible to the real thing,( with the exception of the bow rails,which I'm keeping). The only thing that I'm having real problems with finding,are detail photo's of the cockpit interior. Jeb's pic helped a bit,but I'm trying to find details of the forward face of the cockpit. Can anyone help me out?

Thanks DickyD,but unfortunately no interior shots. I'd found that site already,it's not easy to find photo's of that area of the boat.

Have you tried a PM to cdsc123, he's our resident expert on Vosper launches and he's in touch with a lot of people doing restoration work etc.

Christian also has a web site http://community.webshots.com/user/cdsc123

Glad a bit of history has enabled you to see a difference Dread

Latest trial run,though as you can see,my ACE servo was twitching quite badly,(later packed up),and I'm still having trouble sailing and filming at the same time. I'm getting water seepage through both my rudder and propshafts,both have been heavily greased,and the rudders even have an 'O'-ring fitted at the top of the shafts. Any advice?

Got my Macsmodels castings through today,and all I can say,is that they're superb.I'm going to have to reinforce the boat davits though,as I think that they could easily snap during transportation.I think that i may need to sandwich the core between two plates of brass,as their position on the hull is very exposed.,and I don't want them damaged.

Some pics of the new parts in position,(only temporary,as I still have to paint them).

Sorry for the shaky hands syndrome there.

I'm just waiting for the parts from G.Turner now,and she's more or less complete.I've still to build the companionway hatch though, before anyone says anything.

Dreadstar · « **Reply #44 on:** September 27, 2009, 11:57:59 pm »

How it's looking now.

Still to fill and smooth off the engineroom front face,but I've run out of filler.

That chine rail makes a huge difference.

Well,if you hadn't told me about them,I'd have been none the wiser,so thanks lads. I've also changed my prop from a 40mm 2-blade to a 45mm 2-blade,and it's really quietened down the boat,the only thing is that she now cavitates like stink,and is hyper-sensitive to throttle input.
