Depends if it's heavy just because that's how it was made or if it's heavy because it has water in it...
Old Windsurfers often had the same problem and the cure was to drill a few holes in each and and put it on a machine called "the spinner" which was basically a large machine that spun the board around and the water came out due to centrifugal forces. I don't know if any of these machines are still about but I reckon that's your best bet. Drilling a few holes and leaving in the sun or a hot place such as a car or similar will also drain a bit of water.

poke the corner of a tissue in the hole so it contacts the foam core and hangs out . It will wick the water out and increase the surface area for the water to evaporate from.

i had some good results leaving eps boards outside (undercover probably if you got super sun..) when warm and windy with holes exposed - seems to evaporate water well, ended up lighter.

pic not to scale, forgot to add use a small aerator connection (1/8th I think) to join tube to board hole

I lent my surfboard to a mate yesterday and when he returned it he remarked that it seemed heavy.
When I picked it up I realised he was right. It's an old board but the surfaces look intact. So I'm looking for an informed opinion here. If I drill a couple of holes in it and leave it outiside for a spell is it lightly to drain and then I refill the holes or is there a better method of fixing it. Or perhaps is it time for the bin. The board is not delaminating.It's a Jimmy Lewis.

Tell your mate it was fine before he borrowed it and to buy you a new one.

That keahi bloke must have the same dramas as he's always spinning his board around

Correct me if im wrong, but the pump is sucking the moisture out of the board and into the damp rid where its collected?? Why would you want to collect the moisture?? Just pump it to atmosphere??

Also are you saying your sucking air through the length of the stringer in the board? That little pump wouldnt be able to do that? You would need a perfect seal on the board and in that instance I feel the hose would just collapse??

I'd say you dont have a seal and you just sucking moisture out of the atmosphere??

You've got it back to front I think. The aquarium pump blows normal air into the sealed container of damp rid which dehumidifies the air before the second tube blows the dehumidified air into and through the board before coming out a breather hole at the other end. On the way through the board it picks up he moisture you want out of the board. It's a disgustingly simple and cheap way of dewatering something like a board.

I would get a new mate???clearly he does not care for other peoples equipment.

Yeah sorry mate, should have done a couple arrows on the pic, aerator pumps low pressure air into a pot of damp rid, pushing damp rid vapours into the board, works better and much faster then waiting for board to drip drain


Aseela, if its a jimmy then its worth the effort
