steam pinnace.
« on: May 21, 2020, 08:01:52 pm »

Just bought a book on Phillip & sons, Shipbuilders. On the fly sheet found this outline drawing of a 50ft steam pinnace, with all you chaps building WW1 warships, I thought this may be of interest. Also they seemed to have built quite a number for the Admiralty.

Is that the same as the one in Portsmouth Dockyard?

Hi Colin, could not say, but I expect so, I would surmise the Admiralty used a standard generic plan for all their contractors. With some variations by different contractors, much like warship classes put out to different yards with the contractors adding their own touch here and there. There is a interesting hull for you to look into, the "Research" a non-magnetic hull, a twin mast aux sailing vessel  of 770tons displacement, launched Oct 1937, work suspended, then towed by the P.A.S. tug Atlas to Devonport to be scrapped locally. Beautiful hull lines, make an interesting model for some one. It was built by Philips and son.

There's an excellent book by N.B.J. Stapleton,  Steam Picket Boats and other Small Steam Craft of the Royal Navy.  You can get it on Amazon at the moment for around 8 quid..  It has some great illustrations.  Steam Pinnacles or Picket boats came in several sizes 47 ft,  50 and 53 feet.  They changed ever so slightly depending, presumably, on where they were built.

What is interesting is that not all 50 foot pinnaces were the same beam. Some were about 9 feet and others were about 11 feet. The portsmouth one is the narrower version. I found this out when building Invincible. I used the plans from the anatomy of the ship Dreadnought and they are the wide ones so when built they would not fit on the flying deck.


On checking the Sambrook plans and the original plans in Battlecrusiers they both showed the narrower version. It might not sound much but with 3 abreast at 1/96 scale it makes a difference of 1/4" gap (between the boats) and this made all the difference.

There were also earlier versions with twin side by side funnels. In general they remained unchsnged from about 1880 through to the end of WW2

Chylds Hall models do a really nice 1/48th scale early type Picket boat. (Twin funnel).

The 3pdr Hotchkiss gun is available from 3D Boats on Shapeways.  It comes as a set of 4 guns for less than 10 pounds.

In the background to the photo from TailUk appears to be at least one Torpedo Boat Destroyer (Velox), I am starting to recommision an old torpedo boat destroyer so would like to know more about them and to talk to model boat owners of the early torpedo boat destroyers, thank you

Hi, I have a scratch built model of Velox to 1/48 scale. Actually I extended the hull by about 4 inches and the depth by about 1" as I wanted to put a steam power plant in it and felt wise to accept the slightly non-scale element to get sufficient hull volume and displacement. It all worked fine and the power plant is a Cheddar Models Puffin MK II boiler and my own designed and built double acting in line oscillating steam engine. Maximum  speed is a fast walk and I get 25 mins sailing before I run out of water so tend to bring it in at 23 mins!


As it was steam powered I also increased the main deck superstructure height by 1/4 inch so I could have some ventilation slots. Also I used a small computer fan to duct air directly into the boiler room. I'll try and find some pictures and post them.


I've been sailing her for about nine years now and the only change I have made is to switch to 2.4 radio and install a radio controlled gas cut off valve as too many near misses in running out of water!!


My model was plank on frame using balsa which is rare for me as I find it too fragile but it was then fiberglassed inside and out and has proved to be quite rugged. I was very conscious of weight saving for the steam plant but in the event I needed four pounds of led beneath the boiler to bring it down to the correct water line. I've had no stability issues despite using brass for the guns and If electric powered I would not anticipate any stability problems at all certainly at 1/48 scale.


There is an excellent book from "Shipshape" by David Lyon called The First Destroyers which is probably the best available and contains full plans for Velox. Its about £30 but well worth the cost. There is also an excellent book called British Destroyers 1892 - 1953 by Edgar March. This is a very large volume and has fold out original plans of nearly all the destroyers. Trouble is its long out of print and my second hand copy cost me £90 about 12 years ago but your library may have one you can get hold of.


Hope this helps


Cheers

As an add on there is another good book by Friedman - British Destroyers from earliest days to the second world war. Not bad at all - Amazon £30.


They make very nice and interesting models.

No probs, in the meantime please find Velox. I'll post a new thread on Warships with other pictures
