38 scarab Hull material questions
 

The boat is an old '85 38 flatdeck. The deck apears to have a foam core, that is flexing causing the topside(deck) to stress crack, alot. Is there anything that i can do to stop or fix the problem. Also, Just wondering if anyone can tell me what fiber material my hull is. I do not know how to post pics on here but I attached a link my Facebook that shows pics of the foam section and a few shots of the hull material.
Thank you,
Steve

looks like you could have some Kevlar in that layup. Its most likely a polyester boat and unfortunatly those two combos make for a pretty flexable structure thats prone to surface stress. Kevlar has great tensile properties but a poor ability to handle a compressive load. Not really a lot you can do about it short of bagging a whole new surface on. Its quite common in older wet layed Kevlar up boats. Are the stress cracks individual cracks around edges and corners or multiple waves/fields of cracks?

nice lookin ride! Bad azz with the Arnesons :cool:

there are individual stress cracks around the deck hatches and up and down the center railing, but the two areas I am more concerned with are waves/fields of cracks at each corner at the base of the windshield. as far as the Kevlar, the whole hull it that material, except for the stringers. I keep looking at the one that is for sale in the classified section with arnesons on it too, and I cannot wait to get mine running! Thanks for the help Dave.
