A friend of a friend has a Hobie 16 for sale, about US$1200 (no trailer). I went to see it and it looks good, he seemed a decent guy. First thing he showed me was a spot on the top of one hull (I believe about the size of a hand) that was soft when he got it, but he repaired it.
He repaired it by drilling 2 holes and injecting some kind of resin I think. It doesn't seem soft anymore, although I have no experience with soft spots. He said it was probably from someone stepping on the hull - it was about a step forward of the trampoline.
The only other damage was a small piece around the top of the rudder mount, bit like in this picture
he repaired it but it cracked again.
Any tips/advice welcome, on my first Hobie purchase.
Thanks
PS my friend says he's very trustworthy and would be upfront about problems.
