Sonic 31SS crack along walkway....what to do??
Has anyone else had a crack like this show up along the walkway. I am about to email the pictures to sonic. I am wanting to get this repaired this winter. Started measuring it to see if it is spreading and it did seem a little larger after the beating we took at Ozarks. I am not even sure how to fix this or whom to talk to about it. The crack is right in between where the gunwall side of the top meets the walk platform.

I'm not really a fiberglass guy but you might want to drill a small hole at the end of each crack. That should stop it from spreading. If it doesn't, the problem is probably worse than it asppears. I think any good glass guy could fix you up. Then they're just going to tell you to quit jumpin' those big cruiser wakes.

My 1990 did the same thing. It was there when I bought it. I also discovered the rear bulkhead was rotted and the bulkhead under the helm was very poorly cut and installed. It did not touch the hull most of the way across the boat. May have caused excessive flexing. I took a rasp and ground the crack out. The fiberglass underneath did not look good, like it was dry rotted or delaminating. I filled it with epoxy and filler and gelcoated. Don't now how it held up, I traded it a yr. or so later. I also had tons of spider cracks on the bottom of the boat, and tons of tiny air pockets between the glass and gel.

Bruce from Sonic commented back in an email:
Hey Josh….Bruce here……..very rare but yes the flexing of the deck and hard gelcoat can cause this problem….nothing structural…..but I know not nice to look at…….a fiberglass repair man can sand fill and spray….it should not be that costly…and that should take care of the problem…….By the way what year is your boat?

Is that crack just in front of the fairing?
Could be the bulkhead under the dash. Try hammering all around that area with your fist. Knock on the area from the hull up to that spot and on top of the cabin. Listen for wood against wood or fiberglass against wood. Should be solid. If you don't hear anything I wouldn't worry about it.
