carr, last year I actually bought the book. The local library did not have it. I enjoyed both the book and the movie looooong ago. I knew I was going to build some APA's and was looking for information/inspiration. The ship the book describes is a Bayfield class C3-S-A2 APA, 492' loa and 69.5 beam. Hope to build one in the future.carr wrote:Away All Boats!
Russ, nothing irritates me more than criticism when I am both correct and seriously tried to explain why. The text in the post you replied to discussed both variants of the LCM. Why did you ignore this? The source for all data I quote is Friedman's U.S. Amphibious Ships and Craft.Russ2146 wrote:The LCVPs dhould fit within the cargo decks of the LCMs and the ramps of the LCVPs should be below the tops of the LCM ramps.
From your photos, it appears that the breakwaters attached to the ramps of the LCVPs are too large, both on the purchased boats and on the scratch builds.
There were two variants of the LCM used in WWII.
Type.................LOA............length cargo...........service
LCM(3)...............50'..................31'6"...............1942 to 1944, 1945 modified to (6)
LCM(6)...............56...................37'6"...............1944 +
The LCVP used late in the war was 35'9". It DID NOT easily fit in the 31'6" well of the LCM(3) without the ramp being partially open. It fit very nicely in the 37'6" well of the LCM(6).
L'arsenal's LCVP and LCM(3) are both very accurate. Mine are very close. The Navsource photo that convinced you we were wrong is a May 1945 refit of the Heywood. She was then fitted with LCM(6)s because LCM(3)s no longer were standard, the LCVPs nested very well in the LCM(6). All 1944+ production was (6) and in 1945 the USN CONVERTED (3)s to (6)s.
I am building a 1944 Heywood (pic 1), at that time she carried (3)s.
pic 2 shows Welin davit construction and the poor fit of LCVPs in a LCM(3).
