On the eastport pram? Location of the center board bulkhead and thwart measurment?&nbsp; S&G isn't forgiving if the loctation isn't correct.&nbsp; The owner is searching for the booklet&nbsp; as they are packing up to move and sell the house they are in. I'm trying to get a "feel" before I finish the boat.&nbsp; The posted CLCphotos are of course not clear on deminsions for obivous reasons.&nbsp;

pics coming!

Okay,&nbsp; the forward bulkhead that established the mast step location is 15-1/8" aft of the leading edge of the forward transom.

The bulkhead beneath the center thwart that establishes the aft end of the daggerboard case is located 83 1-1/16" aft of the leading edge of the forward transom.

Oops, too much caffeine, the center thwart is 52-1/4" aft.&nbsp; The aft bulkhead is 83-11/16", not 83 1-1/16".&nbsp; The font spacing is a little weird.&nbsp; Sorry.

Thank you so much Captn! Using&nbsp; the magic number&nbsp; 52.25"&nbsp; the center bulkhead fit perfect and all the others seem to fall into place. Minimal trimming most likely.

I can't access this forum from my cell phone google.&nbsp; it only goes into no response mode LOL
