View Full Version : Is my brandnew Rio M Sport absorbing water?

24th May 2010, 02:39 PM
Yesterday I took my brand new StarBoard Rio M (sports) on it's maiden trip. Afterwards it felt rather bulky so I decided to weigh it this morning.

It appeared that the board weighs 17,3 kg (including rather wet straps)

As the sports version of the M should weigh 13,3 (14,1 Kg. when extra 6% is added) I fear that this board has absorbed some water. A difference of at least 3,2 kg.

Does this make sense? Unfortunately I can't check on leaks around the daggerboard area and the other normaly sealed parts. I am a bit freightened to go back on the water right now.

The posted weight is without straps. I think it would be worth the hassle to take off the straps and weight your board to get a good comparison.

If it's a brand new board that takes in water, I suppose it will be a warranty issue anyway, so I think the best thing is to go back to your dealer let them have a look. If your board fx is 16 kilos (w.o. straps) I figure a replacement could be in question anyway, but I don't know the actual policy on this.

But in ny case, weight it without straps first. Does the board have a vent screw?

Well thank you for your reply... I made the effort and took off the straps. At this point the board weighs 16,6 kg. Just 600 gram more than you mentioned.

Unfortunately I did not weigh the board when I received it :-( (I Bought it for my family last januari, I use some other stuff myself) And fact is I never carried the board alone, until today. So I am not sure what to do now. The dealer where I bought the board is located at over 350 miles from where I live. Not realy a picnic so to say.

What do you recommend me to do? I plan to use it once more. Weigh it again and decide from there.

Btw. The board does have a ventscrew and a rubber ring which were properly in place.

16.6 is for sure heavy. I don't think getting it wet again will do any more damage so do it and weight again. Also (or after) put it in a dry spot and open the vent screw. Place a piece of newspaper paper in the hole "lika a sail". Try to see if the paper gets moist where it contacts the foam core (give it a day or two). And then you need to get in contact with your dealer anyway since all warranties are handled that way so it's better to go through the right channels.

Thank you for your reply. I will do so.

Hi Andre M,
Is the vent screw tightened?
If you remove the vent plug and look at the "O" ring, is it deformed?
The vent screw needs to be snugged down solidly.
As Ola suggests, you will need to get in touch with the dealer/shop where you bought
the board.
They (the dealer/shop) must initiate any warranty claim.
Also as Ola suggests, try the paper towel "wick" in the vent plug hole as this will give you an idea if there is indeed water inside the skins of the board, regardless of where the water entered. (i.e. around dagger board trunk, around fin box, through vent plug,
through footstrap plugs.
Hope this helps,

Hi again Andre,
Actually, you can determine if there is water inside the core of your board pretty easily, and you can even dry most of it out.
It takes some time and patience, but the "technique" is:
In the morning, open the vent plug competely, and stick a paper towel "wick" in (all the way down to the foam
at the bottom of the vent plug hole) to pull up as much moisture as possible as the board heats up during the day as the ambient temperatures come up.
Late in the afternoon, pull out the wick, and close the vent plug snugly.
This will keep the foam core from pulling in more moist air as the afternoon cools into evening.
Also, you can tell if your board is truly "sealed" as when it cools off at night, if you crack the vent
plug slightly, you will hear a "hiss" as the air rushes in to the vacuum inside the core of the board.
If you get the "hiss" then for sure your board is water tight. If not, let the baord warm a bit in the morning,
and go over all the footstrap plugs, around the fin box (top and bottom) and around the center board well
with some soapy water. As the board heats up a little, any air escaping will make soap bubbles and then
you will know where the leak (s) are.
If you get a really warm day, put your board out in the sun with the vent open completely.
If you do not see water collecting (maybe bubbling a bit) at the bottom of the vent hole then most if not all of the water is out of the board.
Heat rises, and hot air can carry alot more moisture than cooler/cold air.
So, over a period of time you can dry out the interior of your board (if, in fact, it's actually wet inside.
Weight is a good thing to check when the board is absolutely new, with no footstraps, but once it's been in the water it's very hard to tell if the board is just heavy (from the manufacturing process (i.e. a bit more glass and resin than absolutely needed)) or if it has taken on some water.
If water shows up at the vent plug, then it's leaking, if no water, I'd bet on a "heavy" board from manufacture.
The only way to really check this out, is to take the board to someone like "The Board Lady" who has a "moisture meter" and can check (ultrasonically) whether there is water in there or not.
Where are you located?
Hope this helps,

OK... thank you for your extensive reply! I will try to do the towel wick test. 2,6Kg. of extra weight should have an effect if it apears to be water. I live in the Netherlands btw.
I have a repair station rather nearby. I think I will give him a call as well.
