D4 Middle Seat Frames

[staehpj1]

I hope it is OK to post this here, since I have not purchased the D4 plans (I do own a set of the V10 plans, but have decided to build a D4 first).<BR><BR>I know some of this has been hashed over plenty already, but I still wonder about the frame that the CB trunk butts up against and the seat top. I know what I think I want to do but am curious about what is the "correct" way.<BR><BR>OK, so I position the frame 10.25" forward of the aft frame for the middle seat. Right?<BR><BR>It looks to me as if that would mean the frame ought to be about 3/4" longer. It looks as if the angles would be the same though. Right?<BR><BR>Will the height of the frame change as well? My guess is that it will not change enough to matter.<BR><BR>Should the seat top be done as drawn, allowing it to hang over past the frame or should it be cut to the 10.25" width. Seems like the extra width would be nice when rowing allowing a little more room to adjust the trim by scooting fore and aft on the seat.<BR><BR>Has anyone actually built the sailing version of the D4 from the current plans with the frames at the proper locations? Seems like every one I have seen has the frames 12" apart and either cut the frame for the trunk or moved the trunk forward.<BR><BR>Pete<BR>

Pete,<BR><BR>You should check at the builders pages on this site. If you look at the Beymer´s D4 (see <!-- BBCode Start --><A HREF="http://www.beymer.com/boat2.html" TARGET="_blank">this link</A><!-- BBCode End -->), you see a perfect example of the trunk protruding into the seat. Thanks to Keith Beymer, you also get <!-- BBCode Start --><A HREF="http://amateurboatbuilding.com/forum/re ... 674&t=3674" TARGET="_blank">this link</A><!-- BBCode End --> to the old forums with one of the first (of many) threads about this issue. Happy new (boating) year!<BR><BR>Greets, Leon Steyns.
