I noticed a 1/2" crack just above where the comptip joins the bottom mast section. Looks like just a shallow surface crack. I was going to put some cheap "marine" epoxy in it - not sure that will do much but I assume it does no harm and the crack is not a big deal. Let me know if that's not the best thing to do. |

The part of the comptip right where it inserts into the aluminum section sees the highest load. I would make sure it's not a structural crack because if it is, just slapping a little epoxy on it isn't going to do anything. I'd rig the boat up, crank the main sheet in real hard, and put the boat on it's side and take a look. See if the crack spreads open or looks worse. If the crack is deeper than just a few thousandths or you can see broken glass fibers, I would not consider it to be non-structural. sm |

Yes, some wishful thinking I suppose. I'd read that there is gelcoat there and I thought (hoped) that was all that was cracked. I doubt I've sailed it much more than 20 hours since new but it does get trailered with the mast assembled. I will take a closer look. It's a Wave BTW. |

Chips and small cracks happen at the joint due to movement while sailing. Very little chance that it is more than cosmetic. |

Grind out the bad, fill it with thickened epoxy and then paint. Repeat as needed. Water will penetrate into the comptip sooner or later, when it freezes...pop. |
