    When my laser had a leak it spent two months of water in the hull and has got considerably heavy and is damp inside. Does anybody know the best way to dry out a laser hull and loose the extra weight from water absorbed into the fiberglass.

    if you have a port hole open it a put a fan next to it and let it dry for a while in the sun.

    Should I blow air in or suck air out

    Lumpydog that looks like an interesting device but I was think of a cheaper alternative for drying out a hull

    i think you blow in?? but is you leave the port open when you not sailing that would help

    Since I live in Ireland we have a relatively wet and damp climate even tho the boat will be inside until june would the moisture in the air prevent the hull from drying out just by leaving the port open.

    The key is airflow through the hull. No sense it blowing an bunch of air in one port if there is not an equal sized opening for the air to get out.

    My boat doesn't have ports, but in the past I have bought an aquarium air pump and stuck a narrow, long rubber hose in through the drain plug. This obviously doesn't have a high volume of airflow, but I left it for several months during the winter when I wasn't sailing. I figure it circulated quite a bit of air through the hull during that time.

    If you left the transom drainplug open would that be sufficient enough to get air to circulate from the bow to stern? Another problem that I am faced with is there is no electricity in the shed my boats is being stored in as it was an old farm shed for cattle that my grandparents own.

    You can make the same type of thing as sold by Intensity. I made one using a fan from Radio Shack and an extra inspection port lid. There must be something similar you can find in Irland. You do need at least two ports as mentioned above.

    The key is just to get some dry, preferably warm air flowing through the hull.

    I brought a hull inside my house once after moving out from parents and before being married.

    If you are married or living with parents this tactic might get you kicked out to the shed.

    The Intensity fan gizmo looks like it would pump a lot of air in the hull. You would need an equal-sized opening, preferably on the other end of the boat, to allow air to escape. Otherwise it's going to try to inflate the hull.

    also you can blow (low pressure) warm air into the hull for a while

    A buddy of mine put an inspection port in the deck, then using solar panels, he attached it to a dehumidifier inside the boat

    Can you get dehumidifiers small enough to fit through the inspection port. I think that that might be a bit extreme it is probably easier to connect a computer fan to batteries a let that run or a few days until they run out

    I would plumb it so the fan is pulling air out of the inspection port. Not pushing it in. Wire it to a bicycle generator. You might as well as get fit while watching your boat dry out.

    So if i can get air to circulate in the hull with a pump or fan for a few months i should loose all the extra weight of the water absorbed by the fiberglass.

    In AU it would be as simple as leaving your boat outside for a couple of weeks in the sun. I've seen several lasers that actually post cure the polyester resin so much that all of the reinforcing blocks show thru the deck. You can also see the mast step thru the hull. We need to keep our dinghys out the sun.
