Is the hull soft? Im guessing its an old boat... The big question is whether or not the integrity of the hull has been compromised. Also.... how hard do you race the boat? The repair for that is rather involved so if its a club level or a recreational thing I'd just leave it alone as long as the hull is reasonably stiff.
It seems to be a common problem with gelcoat. It happens from flexing too much. The hull doesn't seem soft and I think the fiberglass is fine underneath. I don't know anything really about gelcoat but if i were to try and fill the little cracks with gelcoat, it would just happen again.
How does one "sand it smooth"? Should one not fill the cracks first?
I'm asking because I discovered hairline cracks near the centreboard slot and
under the mastfoot on my hull. The cracks are not long nor many,
but I'd like to get rid of them (so that the fibreglass does not soak
up water). The hull is not soft.
I did not see the cracks when I bought the boat (several months ago).
I'm not sure how they appeared. The boat had been in storage for
more than 10 years, and in the past months I sailed it a lot,
sometimes in heavy air.
When I got the laser it had some of the webbed cracks on it. I got the hull for $100, so I figured it will probably be worth it. I only race in the evenings with my local club so I don't think the cracks will make much of a difference for me. My boat handling is more important than that.
$100 dollars? Definately a good choice. What I would do is file out the cracks and then refill with new gelcoat. It's an easy project if it's on the white part of the hull. The difficult part is if it is on the green, as matching colors exactly is a pain. I just did my gray hull and I actually had to mix back and white gelcoats to get the dark charcoal color. You'll probably be fine with gelcoat pigment. I don't believe laser performance stocks your color green. Perhaps there's a place near you that could mix it for you?
Just weigh the choices to fix it carefully. Gelcoat is expensive. A pint is like 44 dollars... which is about half of what your hull cost. I would do it... but I'm also one of those people who has the mindset that a boat never dies... it just needs more repairs!!!
Yeah, the hull is surprisingly stiff and there are no cracks on the green stripe. I figured it was a good deal because of the cam cleats, autobailer and hiking strap that I got the boat with. Thats over $100 right there right?
Do you have an opinion on spraying on gelcoat on the parts that need it? I'm not sure I will end up doing anything, but maybe for a winter project?
