Transom/Hull Joint Water leak?

Our 430 performed quite well offshore from the Chesapeake Bay to Tampa Bay. The 1500 nautical mile trip took 10 days and included a brush with the effects of tropical storm Kyle around Hatteras. Aside from a few hardware issues, the boat held up very well with the exception of a leak originating aft. The water was noted streaming from the vicinity of the exhaust and cableing and traveled to the stbd aft closet and eventually to the bilge. I was not able to see the exact location of the entry. The water was clean and salty with no exhaust odor, taste or color. The leak was especially problematic when the boat was heeled to starboard and ocurred whether sailing or motor-sailing. In the past I have had a Hull/Deck joint leak on the starboard side midships. This was discovered by noting standing water in the area behind the setee where the saloon table is stored. After a section of the rub rail was lifted, the joint was sealed and the rub rail was replaced, the area stayed dry. I assume that the current leak may be from the Transom/Hull Joint especially on the stbd side. Has anyone had a similar experience with Transom/Hull/Deck joint Integrity? I welcome your comments. Thank you. Bob DiSabatino

Congrats with a tough but successful trip!

The trip you just completed is about as tough a test as one can give a larger Hunter, Catalina, Beneteau or Jeanneau. You were started well above 35 degrees latitude during the tail end of the hurricane season along a very, very rough coast. If you can do that kind of stuff without major mishaps, sailing the low-latitude Caribbean, Hawaii or South Pacific (during the right time of year) is a walk in the park. Allow me a short digression. There are people on this board who consider "bluewater performance" the ultimate test for a modern, medium/light production cruiser. Some of them seek the answer in heavier-built vessels, which is a selfdefeating strategy for many of the world's favorite cruising destinations where the often poor upwind performance of these "one-way boats" is going to make them very unhappy. Of course, if you have a couple of extra hundred thousands to spend on carbon and kevlar composite vessels you can "have it all", i.e. strength AND performance. However, as your report and that of other sailors shows, having to compromise a little on strength does not equal having to stay in "chicken harbor" ..... With regard to the leak problem; I agree that the transom/hull joint is the most likely culprit. Assuming that you have been able to exclude a direct leak at the point where the exhaust hose is clamped to its stern tube (both hose clamps should be intact and tight) you may want to check anything screwed low into the transom, including swim ladder, windvane, water generator, etc. It never ceases to amaze me how much water can leak past a single, poorly sealed bolt or screw. Was there much water in the transom locker on that side? Success! Flying Dutchman

leak

I had a hull deck leak at the transome right between the swim latter after removeing the bulkhead it was clear the factory missed a spot with sealer. I called the dealer and they called hunter and it was repaired by a dealer on long island and the dealer and hunter paid the repair bill with no problems at all. The warranty was still inafect and it did have to come out of the water and the repair took one week it all went very well everyone was great.

Thanks Henk

Thank you for your insightful comments. It sounds like you have been there before. In response, the transom lockers have little to no evidence of a leak so I believe as you do that the swim ladder and or exhaust stem fitting may be the culprit. I'm scheduled for service in January, I'll post the result. Bob DiSabatino "Saba"

Same problem on our 410

We also had a small leak in the Transom hull joint, Our's showed up when motering which causes water to swril back on the transom. The dealer pulled the boat and completly redid the joint. It's better than new (especially since it leaked new:) -wayne
