Hi James, The transom of the Navigator/ 17PH etc uses a plywood core for reinforcement. It sounds like the previous fittings and fastenings were not "bedded" into the hull correctly, allowing water to penetrate the laminate and reinforcement. You should ideally tap / hammer test the area of hull to check for delamination. If you're a hardy owners club memeber, give me a call or drop an email, I'm on the membership list - I can then tell you how to do this and what to look for. If you're a member and the boat is local to me at some point I'll have a look for you. Best Regards Simon. HOC2584 HOC tech & Surveyor.

Thanks for the responses Steve and Mike. I have found out since it is actually a 1980 17ph. Not that it changes much. I got someone to blow through the hole in the transom from the outside and I could hear it hissing out in the bilge at the transom. Rain water had been getting in there and I had been emptying it periodically. I should be able to glass the hole up from the inside first easily enough and hopefully then fix a dry outside hole. At least I should have this fixed, the internal refurb and the new motor wired up by the Spring. Was fearing something like the Fishing 24 job. Ta James

Hi James, Without actually seeing where the water is coming from , it is hard to comment . However I would say that your description might suggest that it is water in the hull running to the back of the boat. If you tip the boat forward on the trailer, and it stops and dries , It might suggest that it is indeed bilge water and not any wet foam. It is almost impossible to have a totally dry bilge in my opinion and I have owned and still do own a hardy. steve pickthall

An acquaintance has a Fishing 24 and he found a foam in his hull which he cut out and allowed the hull to dry. He had to cut the floor out in sections, hack the foam out and then glass the floor back. All in all it took about one year, though he did most of the work himself. Email me if you want to find out more and I can find out if he is happy to talk to you.

I bought a hardy about two months ago. As yet still a few jobs to do before it gets wet. I took off a depth finder that had been riveted on (upside down) on the transome. Drilled out the rivets with the intention of filling the holes and attaching it properly. However the bottom hole wont seem to dry out. I drilled it out weeks ago and I still get water driipping out when I prod something into it. It's about 2'' above the base of the boat. It makes me think the water is getting in the top and settling in the core. Does anyone know if there is a polystyrene core? It feels spongy when I probe it. I've no ideas where it might be leaking in or what I could do to resolve it? I have tipped the boat (an 80's Navigator) up on the trailer a bit to aid it drying out before glassing and gel coating the holes and could tip it more severly if needs be. Otherwise I'm at a bit of a wall. Any suggestions most welcome. Am a new member but number not handy. Thanks
