After the Rattlesnake I wanted to do something different. I have always been interested in the WW2 PT (Patrol Torpedo) boat. My build will be modelled on PT 105 commanded by Dick Keresey. Yes believe it or not they made other PTs besides the 109. The 105 was an 80 foot Elco Torpedo boat 1942, built of spruce, oak and mahogany and made watertight by marine plywood covering.
The Dumas kit 1233, 4 large sheet plans, decent 45 page instruction book, ok pictures, good material list. Kit is supplied with Mahogany, birch, and poplar ply. Dumas decided to replace the Mahogany sheet hull planking with 2mm PVC they say it makes for a smother finial finish. OK however if I wanted to build a PVC boat, I would have bought one. I will buy 2mm Mahogany sheets to do the hull planking properly

You've got my attention also. Looks like a fun build and so different after the Rattlesnake.

The plans include R/C installation, I plan to go the static route
Now I have time on my hands, retirement time, I have wanted to do a PT for years, have spent the past year reading allot about the boats and crews, A PT boat Captain who witnessed an Elco PT being built said “ What I saw was a group of boatbuilders ,building boats by hand. If a builder who had crafted clipper ships had been resurrected, he could have joined that group with no problem.” “Nothing was nailed everything was fastened in place with screws, bolts, glue or a combination on three” Craftmanship and all wood fast boat, armed to the teeth what’s not to love.

PT boat the British MTB or German Schnellboot do have great war story to tell.
They saw a lots of action in the British channel
I am following the build of one Schnellboot 1/35 from Italéri on a French forum
Those are great model.

For framing and planking the PT boats were built upside down. The prefabricated bulkheads were lined up on a template on the floor of the building shed. Following this original building style. A building board (shed floor) is marked out following measurements from the plans to form a template for centring the keel, and lines for placing the bulkheads. The keel and frame 1-6 are placed on the board with the keel and frame 1 and 6 glued to the board. A lower sheer is added to both sides & the rest of the frames a dry fitted, checked for alinement, the feet of the frames are glued to the board. Then the chine is added to the upper frames once the lines look good the frames are glued to the keel.
Being a different way to build some trial and error came into play, however after working at getting the whole thing centred it was a simple process, the only error was frame 1 moved during drying and did not fit square to the keel. I used a holding block to help get the frame & sheer as close as stress would allow.
