i had Mike at Lake fork fiberglass do it on my old 20ft. Dual Console Bullet.
i had him only add a couple of layers, and sharpen the strakes on the pad ONLY. it didn't slow the boat down at all, and actually made it handle better at high speeds.
life time warranty on damage!
he didn't add any weight forward of the console as i didn't want to loose bow lift. which is the problem with alot of guys that have that done. it adds weight to the front of the boat making it nearly impossible to get the bow lift back, which causes the boat to loose MPH at topend. usually 3-5mph loss.
