I was ready to wire in the bulkheads of my C17LT when I discovered a discrepancy in positions between the plans and the instruction book. The plans have the fore bulkhead at 61 3/8" from the bow while the instruction book mentions 64". Likewise the Aft bulkhead on the plans is at 121 1/4" vs. 124" in the book. Furthermore, the deckbeam is 89 1/2" in the plans and 93" in the book. Intuition tells me I'll be alright as long as I can 1.) leave enough leg room in the cockpit with teh fore bulkhead and 2.) make sure there is enough room between the deckbeam and aft bulkhead for the coaming.
My prime concern is whether those 2 3/4" in positioning the deckbeam and aft bulkhead will affect the trim of the boat in the water once I get my 200 lb future son-in-law aboard? Doesn't sound like much, but I'm not sure how it translates into actual fore/aft balance?
