    Has anyone used old life jackets stuffed into the areas in question?

    Re: Positive bouyancy question.

    don't do it unless you have removed all resembelence of it being a life jacket........otherwise you could be zipped for having "expired safety" equipment aboard.

    and to make a significant difference you would need quite a few life jackets.... unless it was a kayak.

    cheers
    Its the details, those little details, that make the difference.

    Thanks,

    They would be in areas that would not see and the life jackets are new ones (basic $15) and surplus to my needs.

    Thanks

    I looked at EVA sheets today at Clark Rubber they have a range of densities,in thicknesses up to 25mm, The really dense stuff was rated at 250. Execise mats rate at 30-40, door mats at 90 ( $30/mt though)
    Bias had tinny seat cushions, that rated about 50 but they were not stable if exposed to fuel/oil,,,,,,
    The search goes on...

    if you are looking for something fuel and oil resistant, you wont have may chioces... and you wont find those choices in a retail foam supplier.

    As you are betting your life on it,why not use the best.

    Polyethylene Foam

    Easy to shape with a sharp carving knife.
    Sticks like the proverbial if you use Marine Sikaflex(I had to remove a piece and it tore the foam ,it sticks so well)

    The agents are

    I know this is going to sound laughable, but many times over the years I've wondered how slightly modified old large gas cylinders would go welded/attached to the exterior of the gunnels. They could be foam filled and sealed for life. And they're gal.

    Just a thought...............might be a stupid one though.

    Re: Positive bouyancy question.

    hehehe!! Yeah it's sort of hard to describe what I had in mind. They actually be a bit below the height of the gunnels, with wide coamings encompassing them, if you know what I mean. If not foam filled, an air valve could be fitted and just check the pressure every time you fuel up.

    Could even do it with a few 9kg bottles and make one a livewell

    Dreams, dreams..........ahhh the medication begins to bite.

    Dave you would want to be fast as a BBQ maker is using a lot. BBQ for the boat or heater for the overnighters ( no I won't have flames on boats)

    Believe it or not ping pong balls are commonly used to keep a holed ship afloat by salvage companies.

    Re: Positive bouyancy question.

    all the gas cylinders I have lumped and humped would be a bit heavy for strapping to a boat unless it was a coal barge.

    Gass cylinders in water float barely even when empty.


    Ahh the old ping pong balls......definitely used by Daffy Duck and his three lads..... and proven as plausable by mythbusters ... but I have my doubts about an actulal commercial application.

    the problem is they will leak out thu holes in the hull.

    Don't forget bean bag beans - maybe we should all use those pool bean bags

    Re: Positive bouyancy question.

    Or better still, just keep one of those floating pool arm chairs in your boat.
    As the boats sinking, just plonk your ass into the chair and float calmly away with a beer in one hand and your EPIRB in the other.
