So, I've browsed these pages since I joined and gained a ton of knowledge from them, so thank you. I have a 1985 Ebbtide Dynatrak that a previous owner had backed it into a post causing a bit of damage. I just want to make this water tight so I can get it in the water this season and over the winter I plan on doing a more extensive project.
Here is my current issue. This crack was a decent size crack so I cut out the portions of damaged glass and wood. Based on advice from one of the local marine repair shops, I used bondo glass as a filler and was planning on simply spraying some gel coat over it for this year. Unfortunately, the damage is directly above the bunk so all the vibration and weight of the boat hits it full force. I didn't necessarily trust the repair shops comments that this would be enough, so before gel coating it, I took the boat for a drive around some rough roads to test the strength. I, unfortunatly was proved correct and a small hairline crack reformed. So, I decided I need to glass over this to give it some strength. I sanded a portion around the damage (between 2-3 inches beyond the actual damage) through the paint to have glass to re-glass to. I hope that was needed and I didn't just ugly up my boat for no reason.
Anyways, my main question is how far should I extend the new glass to ensure proper strength. The picture below is just the transom side, but the bottom of the boat is an almost mirror image of this as far as how far I sanded out.
I'm thinking about using a couple layers of woven roving and I'll float it in to hopefully not make the patch too obvious. Would CSM covered with mat be a better option? The damage really isn't that bad, but I extremely concerned about the location and how much vibration it will have to put up with so I want something strong.
Thanks for the help, and sorry for the book.
