Posted: Sun Aug 21, 2016 11:44 pm Post subject: MY BOARD IS HEAVY |
|
|
I bought a used 78l naish global earlier this spring. After only a couple of sessions a crack developed from the rail up towards the foot strap.
this was proffesionally repaired. Sailed once thereafter and realized the board got extremely heavy. Put It on a scale and it had gained a hefty 8 ibs ( from 14.5 to 22.5ibs )
Had it back to the repair shop, we realized a small section of the skin butting up against the mast track had delaminated and was sucking jn water... not good
a month later, board is down to 18.5 ibs, still more then 30% heavier then the 14.5 ibs when I bought it ( it was a used board )
10 small drain holes around the mast track, 2 holes in the tail ( 1/4 " ) , one drain hole in the nose , a few random holes here and there and full month of Oregon summer sun. There is absolutely zero moisture in any part of the board that is open. I tried the paper wick method , it is so dry it crumples when I check for moisture
Where is the extra weight ? I assume moisture is trapped somewhere, but where and how do I extract it ?
The repair guy is very reputable, there is no way his repair added 4 ibs in fiberglass/ epoxy
4 ibs might not sound much but the board sails like a truck. it was very " sporty " back in its lighter days, the extra weight has completely ruined the light crispy feel it once had |

See the board lady web site
topic water in board.
My guess is the repair guy didn't dry it properly before
repairing it.

vacuum pump or spinner needed. |

Pumping the thing down should work, you just have to figure out how to attach the pump.

The repair person should have a vacuum pump, if like the boardlady shows this doesn't lighten up, I say don't waste any more effort.
A vacuum pump from like harbor freight is 100$-+, you need fittings and hose yet, cost around 200 total. _________________ K4 fins

has anyone tried the vaccum method ?
if so, please help me out with any details
Do you put the whole board in a bag ? Or just bag the tail or nose and create a vaccum right there ?
the point I assume is to create a pressure differential between the inside of the board and outside |

The 2nd post by ctuna , has the link to some general information.

This shows some more.
The point of the vacuum is to extract the water by sucking it out. _________________ K4 fins

A very very small amount of water might come out via the differential pressure induced by the vacuum, but almost all the water will come out because it boils off at practically ambient temperatures once you pull a full vacuum. Put it in a vacuum bag in the sun and you'll be amazed at how much water you get in the condensate pot (remember to use a condensate pot so you don't pull all that water through your vacuum pump.). _________________ Kansas City |

Even the board lady admits nothing will get all the moisture out. What's left will permanently threaten the core's integrity and its bond to the skin. It's time to start looking for a replacement. Whenever I find a board I like that much, I scour the swap meets and used board sources for backups, which are usually much cheaper than significant repairs. |
