I was able to find enough information at the UNO archives to build a model of PT 564, however no information on how the hull planking was orientated and if the deck was planked or sheeted.
Still in the planning stages and gathering materials, so can anyone answer either of those two questions? Thanks for your help and Happy Holidays to all.

I got these specs from several Higgins drawings (http://www.pt103.com/images/ptpics/higgins/hellcat/PT_564_Higgins_Hellcat_1943.zip):
Deck planking:
Inner layer: 5/16 x 5 orford cedar
Outer layer: 7/16 x 5 mahogany
Side planking:
3/4 mahogany ply 8' 0 x 74' 0
Bottom planking
Inner layer: 1/4 mahogany ply 48 x 14' 0
Outer layer: 3/4 mahogany in 8, 10, 12 and 15 widths
Transom planking:
3/4 mahogany ply 9' 0 x 15' 0
I have no drawing specific to the Hellcat showing planking orientation, sorry.
Happy Holidays to you too Larry!

Thanks for your reply, I have all the drawings you provided and from them have drawn the frame plans. This will be a 1/20th RC boat, some I'm not shooting for museum quality, just trying to keep it real as far as construction techniques.

So in doing further research on the Hellcat I have noticed a few things that differed on her compared to the other boats of the day.
In viewing the Higgins prints from the UNO archives it appears the Hellcat lacked some of the usual features found on other PT's.
There are no deck mounted ventilators or intakes for engine air, no toe rails on the fore deck, no dead lights in the decks. She also carried more fuel than the contemporary boats of the time, her tanks could hold 3600+ gallons of gas.
Dr, Ross supplied a photo which also showed she had an unusual helm position and bridge area.
If anyone else has any pertinent information on the Hellcat, drawings, pic's, whatever I would appreciate you sharing, thanks.

Larry;
While the larger boats were becoming more gunboats as the war progressed, PT 564 was originally designed as a pure torpedo boat, speed and maneuverability being the main focus, this is why the design was more streamlined and larger fuel capacity was added. This boat could run rings around a Higgins 78 and an ELCO 80. Many Skippers just back from Guadalcanal, who tested it, gave it very high marks, but eventually because it was determined the larger boats could still serve the purpose, it was deemed unnecessary by Bureau of Ships/Big Navy.
Take care,
TED

Frank, thanks for those photo's, they clarify the bridge and helm area, and helped tremendously in my figuring how to build that area.
