    I have a leak on the side decks of My 2015 MH-37 that we bought new. Been fighting to get these fixed for a couple of years with dealer. First attempt made the port side better, but resulted in worse leaks on starboard side. They tried removing and rebedding the fixed cabin ports. Has anyone else experienced this with a late model Marlow-Hunter and have a success story to share.

    Another view, showing the water running back to the aft bulkhead above the galley. 20170810_090858.jpg

    Production Boats are not known for consistent quality so chances are that another boat may have a different kind of problems than yours. Ours came with thin spots in the cockpit fiberglass that eventually turned into holes. We discovered after five years that the emergency manual gusher pump had been crushed during installation and would have been inoperative in case of emergency. Our 32' boat came equipped with a headsail furler rated at maximum for a 30' boat. Some designer may have decided that with a small headsail it would be adequate as well as cheaper but for us it resulted in a broken tack ring. The furler manufacturer replaced the unit with a beefed up one they had already developed but no one offered to cover the riggin costs. And the list goes on. We are partly to blame because we want a boat with all the bells and whistles at a bargain price and that is what the production boat manufacturers deliver. Labor is not paid well and it shows in lack of care, costly mistakes are hidden rather than fixed and to get them to make good on the warrantee requires a miracle worker. But all in all if they were not around we probably could not afford the boat we have.

    If you have a 32' boat with a fractional rig then you may be able to use a shorter fuller foil, say for a 30' full rig.

    From your pictures of the leak, the leak appears to be above the level of the fixed cabin ports. If this is true, I don't see how re-bedding them would help. Have you tried after the boat is totally dry spraying water in specific areas to localize the location of the leak? Have you taken down the headliner to help find the source of the leak?

    Water leaks travel all over and as said see if you can take things apart to find your leak
    and have some one top side with garden hose and you watch below for leak or get one of those smartphone long snake camera and use it up in those hard to get area and do same with garden hoses.

    Haven't had leaks like that on our MH37. The mast step/compression post join leaked after acceptance of the boat. Dealer pulled mast, sealed, then restepped. No problems since. Did you look at that? Does compression post show any sign of rust below the head liner?

    Dealership is coming up to start disassembly at end of month. We'll see what they find. I don't want to take any thing a part as long as the dealer is honoring the warranty.

    Juice, I can understand not wanting to take the boat apart. But if you can help to localize the problem, I think you have a better chance of a lasting fix.

    The electric leaf blower and soapy water trick may be indicated for finding this one.. Non invasive and accurate..
    Shut all hatches, ports, vents, etc. in the companionway, make one of the washboards of cardboard with a hole in it to match the blower outlet.. Mix up some soapy water to make bubbles.. apply blower to the cardboard hole and paint/spritz the soapy water over the cabin top and fixed ports and all penetrations.. Look for bubbles caused by the escaping air. That way, you can point the dealer to the suspected areas and possibly avoid a lot of de-construction.
