    Default Seawind 1250 Laminate cracking.

    One of the new Seawind 1250's out of Vietnam has suffered from cracks appearing in the laminate panels around the TV and both aft doors.
    These are not due to structural loads as the boat has only been sallied from Brisbane to Cairns.
    The boat has had little use and has spent most of its life in the marina.
    Any views as to a possible cause would be appreciated.

    Do you have any pictures?

    Nothing works on an old boat, except the skipper.

    Photos would help quite a bit. How did you determine that these are cracks in the laminate and not just the gelcoat? Gelcoat cracks are not uncommon and do not affect the structure.

    Will add photos as soon as I work out how to do it.
    The cracks, ten in total, are in the wood laminate used on the interior of the vessel.
    I used a razor to determine the depth and found it to be the depth of the laminate only, 1 to 2 mm.

    Here are three photos, you may have to rotate them, don't know why it does that, but you get the picture, so to speak.

    From the photos, my sense is that they are not so bad. The cracks in the veneer may simply represent crazing of the wood with humidity and temperature change. It's hard to tell if the gelcoat crack is just crazing or a crack in the laminate without chipping away the gelcoat to have a look at the underlying laminate. A lot of boats have gelcoat cracks in areas of high stress and movement that do not affect the underlying laminate and structural integrity. If it is concerning it would be worthwhile to have a surveyor take a look. If it is a new boat then Seawind may be willing to cover that.

    A boat properly designed and built does not crack like that. Simple.

    Not necessarily.

    Fibreglass can flex more than most laminates. Rigid laminates glued onto fibreglass panels can not move so they have to crack. Heat or cold and moisture can cause different rates of expansion.
    Older boats with less rigid bonding could creak rather than crack.

    I would have thought that those cracks are not significant. But of course they need watching.

    Have you taken this up with Seawind yet? I've always found them to be very responsive. That would have been my first move.
    After looking one more time I realize you aren't the op. This maybe shouldn't happen, but I wonder if it's structural. Hopefully Seawind will get a chance to answer.

    Thanks to all for your inputs and interest.
    Seawind in Vietnam have been notified and are working towards a solution.
    Some of the laminate has been removed and there was no evidence of structural failure underneath.
    If the veneer is sourced locally, it main have a high moisture content to start with and if exposed to a less humid environment, then changes may occur.
    None the less, it is not good for a new boat to suffer from this issue.
    More news to follow.

    Looks like the use of a dehumidifier may have reduced the moisture content in the veneer to an extent to make it crack.
    Hopefully a compromise between Seawind and the owner will result in the necessary repairs being made.
    Safe sailing.

    Yep, Dehumidifier shouldn't be left running continuously, I understand the factory did replace even though not strictly a warranty issue
