In an effort to not get "head" room and ceiling clearance confused, I would like to ask what size the exposed deck strengtheners on a PT boat were?

I am building the interior of the Elco 80' and I want to show below the deck with the beams and such. I have very few photographs that I have found where anyone seemed to need pictures of the ceiling.

Victors book does have a very good drawing of the layout but I confess that even reading the .pdf "Naval Specifications for Motor Torpedo Boats"
has not given me any insight into how large these pieces of wood were.

I have not yet been able to purchase the DVD yet as I have been unable to find a job for the last 15 months and I am really trying to keep myself out of trouble by concentrating on task which keep my brain working hard.

I am using the parts from old balsa wood airplane kits for the materials that I was given.

Any help from anyone who can remember about how large the pieces were would be very appreciated.

Denny

I can't tell you the measurements between the cabin soles and the bottoms of the deck beams but I can tell you, having had the opportunity to spend several hours inside the Elco boat at Fall River than there is one transverse beam about midway in the crew's quarters up forward that is larger and hangs lower than the rest of the beams. I know this because I repeatedly hit my head on it as I explored the boat. I am 6' 2".

Perhaps you could get some of the basic sole to deck beam measurements from the curator at the PT exhibit at Battleship Cove in Fall River.

Denny,

There's a black & white still from the movie "PT 109" of James Gregory, Robert Blake, Cliff Robertson, and Ty Hardin standing on/in the set of the re-created forward crew's quarters of PT 109 on this Getty Images link:

http://www.gettyimages.ca/detail/2850265/Hulton-Archive

The still shows the (approximate) headroom below decks, at least in the forward crew's quarters. I'm pretty sure all the actors were/are probably shorter than C Marin's 6' 2"!

At 6' 0" I do not remember having any problem with the overhead except when going through a hatch.

As far as the deck beams go, they varied in width and height. I have a table of the dimensions towards the bottom of the page here:

Always happy to help keep a fellow delinquent off the streets.

Hi Denny,
Bill Maloney has some interior photos of both PT Boats at Fall RIver Museum PT617 and PT796. He has some interior photos showing your deck beams. You may be able to guess from the photos the correct size. I will post them below. Go to this link http://www.williammaloney.com/Aviation/PTBoat/index.htm to see more of them. Jerry

Thanks for the help guys.

Jerry, I have downloaded all of the pictures from the 617 and those pictures are a big help.

Jeff, your drawings and specs on your 103 boat site are making me wish I had gotten the 109 boat (even with its flaws) for Christmas. Those pieces are absolute artwork my friend, I have not been on this forum long enough to know what you do for a living but if the drawing and computer rendering I have seen on your sight is a sample of your expertise, I can only say WHOA!

Do you happen to have any drawings similar to the drawing on page 147 of Allied Coastal Craft Vol 2? Deck layout? I photocopied the deck layout from Victor Chun's Book and it's been so long since I have done any mechanical drawing I can't tell which side was from the top and which was from the bottom.

Thank you Denny, I appreciate that! I do 3D graphics as a hobby, it's what keeps ME out of trouble... Getting paid for it does have a certain attraction though.

Sorry, but I don't have a deck layout yet, still working on the parts. Thanks to Dick's DVD and a frame offset drawing on it I have a hull I can have faith in as far as accuracy goes. Now I'm working on the outside structures, not sure if I'm going to do any interior work although I have most of the chart room done. The interior is amazingly complex, I salute your effort to recreate it and look forward to seeing the finished model.

In looking at Bill Maloney's photos I now see what I was hitting my head on all the time in the crew's quarters on the 617 boat at Fall River. There is an "arch" beam about halfway forward in the crew's quarters. It is the support that the fire extinguisher is mounted on. It's visible in his photos 14 and 17 in the "Crew's Quarters" photo section. This structure appears to be a "cutaway bulkhead, perhaps installed to help stiffen the forward section of the hull.

Request to Dick Washichek,
Hey Dick, as the webmaster would you be able to add the links to Bill Maloneys website photos of the PT617 and PT796 in Fall River? I have them here and they would be a good thing to have handy for future PT boat enthusiasts. Jerry PT658 Portland
