Hull Taper

Post by Seven3 » Thu Oct 03, 2019 10:23 pm

Just curious about the science behind figuring what taper to bend the sheets of a riveted hull at (stern to bow taper). You look at some of the old Thurmans and they have a lot of taper making the bow deeper. But the later Thurmans, and the newer Benny Webb’s have less taper. The Don Davis’ and Wardaddy’s seem to have a lot less taper. Is it all just about getting the boat to jump up on plane quicker?

Yes, I build mine with 5" of taper per side they tend to be on plane with a throttle blip, wider is better.

The older thurman hulls had heavy taper to drop the nose farther, those boats were built specifically to have a proper sized drawer on each side to haul a certain size package(s) that were extracted from certain areas back in the good ole boy days, wink wink.

If there's any residue in there, I'll have to blame the previous owner. 8) :lol: :lol:
