Bottom paint at or above d.w.l.

Post by weller » Tue Apr 30, 2013 5:58 pm

I'm ready to paint the bottom, but I'm not sure if the d.w.l. on the prints is where I stop the paint or do I paint 2" or so above that line?

I believe most people paint their boot stripe centered on the DWL...good question though!

My inclination ( and past history) leans towards painting 1 or 2 inches above the DWL, then adding a bootstripe above that. Years ago a very experience custom boat builder advised me to always raise the waterline at least 3 inches ( this on a 34' sailboat) since in his experience designers were selling plans and their weight figures were always pessimistic. He was absolutely correct in that field.

Agree with Doug... dwl is based on design displacement which is less than fully loaded weight. Add a couple of inches so you'll still see some bootstripe above water when you've got the seats and tanks filled. The Glen-L design notes often indicate a weight per inch of immersion which you can use to estimate the highest waterline you might need.
