Re: Spider Cracks A Cause For Concern?
Good question.
The reasons for the spider cracks may lie in your question as well.
Could be flexing, maybe hit the dock a little too hard at sometime, the gelcoat may have been applied a little too heavy in a corner or an edge at the factory, too heavy and it can crack. The boat is going on twenty years old and it happens. I'd be surprised to find an older boat without them.
I am having some repaired over the winter but they are below the waterline and are being covered over afterwards with a barrier coat. If yours are above the waterline, a repair may crack again if it is flexing.
If you can live with them, it might be better to leave them alone. I'm sure there are others here that have more experience and knolwledge about this then I do and will post a comment or two.
