Passing on great news...that after 2 seasons of too much water in the port hull...and not finding the leak with many trys...we found it after dis-assembling the rear crossbar from the port hull...the crack was behind the slug below the lip where the 9/16's nut is held. We never saw soap bubbles when we tested near there. I don't think we could ever really see behind the slug. Now if we can get a pair of used daggerboards! |

Outside or inside??? It's more common on the outside but happens on both sides. To fix it you'll need to install a hullport behind the rear crossbar so you can access the inside to repair the cracks by installing several layers of fiberglass. Order "Curved" Hull Ports (screw-in type) as the hull is curved. Install the hullport so that you can reach the underside of the crossbar and also reach the transom on the inside. If you ever break off a gudgeon screw you can reach it from the inside w/ visegrips or just remove the whole gudgeon backing plate and replace it. Or you can just cut-out a patch on the in-board side of the hull .... a 15* bevel (like carving a pumpkin) using a jig saw works well .... fix the cracks at the crossbar ... then re-install the cut-out patch and re-skin/fair/gelcoat. Been there ... done both methods .... |

Yipes...we used silicone sealant and put everything back together...we'll see how long it lasts...hopefully all sailing season. Thanks for the tips. |

Certain years of the 18s were prone to failure of the hull/deck joint (mid '80s). My boat developed some considerable cracking at the crossbar joints and required fiberglass work inside and out- no way silicone caulk would suffice. It also leaked like a seive until I fixed it. It sounds like you've probably only got a small, isloated crack. But it still may be worthwhile to give the entire boat a look-over at the crossbar/hull connections to make sure it's not something more sever. sm |
