    The following quote is taken from a piece of literature (manual) that was utilized by the NidaCore company as a sales pitch in support of their PP honeycomb core product.

    There are no other specifics supplied,...such as name of vessel, charter organization, island location or marina where this was carried out, what hurricane, etc. And it may have occurred before wide spread info dissemination by the internet came into being?

    Is there anyone with any more knowledge as to the details of this 'event' ??

    Sounds like a Sales Pitch to me. I would also think the parking lot surface (concrete) would be damaged.

    OK here is the latest info I can uncover. This was sent to me by a gentleman working for nidacore division of 3M

    I found these photos of one of his vessels,...I believe the one in the Bahamas

    Janot was just in my office and I have sent him the link to this post, I think the latter story is correct and his boats are very well built, there is still one operating here that has stood the test of time. I hope he gives some more input soon.

    Brian... many years ago... now 32... a company my brother and I owned experimented with a cored graphite skin structure for wings (aero not water). The idea was to allow an internal mechanism change the wing shape and also as impact improvement for small stones kicked up on landing a takeoff landing.

    Anyway, we experimented with several layup designs all with resin contents of 27-32% resin (epoxide) to skin material (less core) mass. We found that thin carbon composite skins with a polyethylene foam core of about 4-8 lbs per cubic foot were very good... now what was interesting is it was extremely impact damage tolerant and had good rigidity for the use... note these core thicknesses were in the range of 0.1" to .2" for reference.

    Now later some work was done with similar materials for survivability proposes... very good to its limits.

    What was strange was the flexible core would transfer the impact loads and protect the skins from localized impact damage...

    JUST LIKE YOU TALK ABOUT HERE... !
