Ed, my grandson always worries about the knocks his boat gets but I tell hims that's life, but we can fix it together, that way he is learning valuable skills that will last him for years after I've gone.
Cheers Colin. ▲

Colin H, he was indeed smiling! For me, the pleasure is in the building and I hope he enjoys really using it the way he wants to, rather than keeping it on a shelf. Damage is bound to happen, but if he brings enough pieces back, I've told him I can rebuild it!

The smile says it all. (YOUR THE GREATEST. )
Lucky lad, at least he's joining an elite club and maybe one day he'll build his own.. cheers Colin. ▲

Chris, the flare was indeed a challenge. In the first third of the hull, the bulkheads are 1 1/4" apart and the remainder are 2 1/2", plus each bulkhead is 1/8" thick. This was not a problem as I'm not doing the interior and it did make following the curves a lot more accurate.
I did a dry run for each sheet, clamping the fir strips as hard as I dared, then leaving them overnight with wet paper towel over both the strips and sheet. Next day I cinched them all the way in and again left them all day, soaking. When I eventually glued them, they had taken on a shape, but still required a lot of pressure. I normally fiberglass my hulls, but I'm trying to keep the weight down as my grandson wants something really fast. It weighs very little, which will restrict it to flat calm days, but it should fly, hopefully in a straight line. My Black Watch 30 model, which has the same lines, is a heavy boat with lots of twin engine power (picture), but is absolutely controllable at way over scale speed, so the hull is proven. I put some power into the RAF Crash Tender and this gets unstable with too much throttle, at much lower speeds than the BW30. I've heard the same with models of older hull designs like the tenders and PT boats ▲

Could be one of my Fairey hulls! Which do of course have links.
I know what you mean about the flare, had a right game with my Huntsman 31. Used thin birch ply and had to slit it and fill with P38 to get a smooth curve. If doing again would use more formers like you have. Your build is coming along well and looks great. Chris ▲

If you send me a private message with your email address, I will see if I can find the plan that I have and send it to you.

Madwelshman, I only currently have rather blurred photographs of Blue Moppie's superstructure, so there may be a bit of βinterpretationβ. The hull is fine as Iβve got accurate line drawings of the Black Watch, which is so similar. If anyone has drawings or an aerial shot from roughly above they would be appreciated!

ChrisF, I would use this method again, especially for difficult curves. I essentially built the boat from the inside out, so no foam was visible when the cabin top was removed. You have to paint the foam when sanded to avoid issues with the resin

The Moppie boats are quite famous in the offshore world aren't they.
Great to see a slightly more unusual boat/lesser seen boat being built. I think I have plans, including top sides for 'Brave Moppie'. There were 5 versions of boat all sharing the same hull, just with different superstructure, Huntress and Brave Moppie being two of them. Will be following the build with interest. Will ▲

I've seen foam blocks being used but not spray foam. But you've made it work well and ended up with a nice model. With inbuilt buoyancy as well!

The bow is very similar in the two boats and not easy to replicate with full sheets of wood, even with many bulkheads and 1/16" Bass. The next post will show the result!
I used a totally different method on 'Huntress', the sister ship model. I sprayed expanding foam between the bulkheads, sanded it to shape, then fiberglassed the whole thing, using very fine cloth. No problem with curves this way! Incidentally in the real boat the extreme flair really works. I have been caught in some heavy seas off the Maine Coast and the flair just powers the waves aside. ▲

It has got some curves hasn't it! I used some thin ply in the bow area of my Huntsman 31 which has pronounced flare. I still had to slit the ply and use some P38 filler to get a smooth curve. I haven't got as many formers as you have though and if building the hull again would add more.
Interesting history about your Black Watch 30 and it's links with Fairey. I'm building 5 at the moment and 2 more in the pipeline. Thanks for the link to the Cowes-Torquay race. I've watched the 1969 Round Britain a few times and picked up a copy of the original book. ▲

Thanks ChrisF. The frames are all Bass wood so everything is still very light. The hull will be 1/16" as there are some horrendous curves, but I'm hoping with all those bulkheads and the many lift strakes running the full length, that this hull has, it will be strong enough.
My Huntress is a 1" to 1' model of our Black Watch 30, built in 1989 by Ted Hood at Little Harbor. It was designed by Ray Hunt, who of course had a hand in designing the original Fairey boats. The Bertram 31 hull, which he did later and was so revolutionary in the industry, is the same deep V, but is somewhat different. The Black Watch has very similar lines to the Bertram 31, so although I'm cheating a bit, it's very close. I got the line drawings from Ted Hood's biography. I've had a lot of fun looking at clips from the 1962 Cowes to Torquay powerboat race which I remember following as a kid. ![]() ▲

Yep, I like to build some unusual models as well as the more common ones and yours is interesting.
I don't think you need worry about saving weight by not glassing the hull when you have all those bulkheads/frames! Your Huntress is interesting as well. Was it adapted from the Fairey design? Chris ▲

Interesting project Ed, nice to see something unusual being built, interested to see how it turns out.
