Anyone on here ever weigh their boards with a baseline measurement to refer to any time they think it may have taken on water? Been thinking of doing that with the quiver as a simple reference point for when the dings come about.

When a ding starts to take in water, it may only be a few fluid ounces at a time... which will change the weight of your board by only a few oz at at time as well, because the weight of water and the volume of water are almost the same, when measured in oz. Dirty wax might weigh more/less, so this may not be a good method to tell if your board is taking in water.

Thanks LB, those are good points. I see what you mean about the wax. I would imagine that water in the foam would affect buoyancy proportionately to the increase in percentage of overall board weight previous to the ding or crack taking water on. For instance, 6oz of water in a 7lb board is more compromising to floatation comparative to 6oz water in a 9lb board.
Though a relative question if my previous statement is true, what's a range of added weight from water taken on that starts to really affect floatation?
I've seen the methods used on boardlady.com and they seem pretty good although somewhat intensive to measuring water in the board.
Question for you guys (instead of starting a new thread):
Got an old 80's/early 90's sunbeaten board that is fairly ugly but in good shape. I was planning on fixing it up to give to my nephew- teaching him to surf... The board has some large ugly inlays under the fiberglass and was trying to think of a quick/inexpensive way to cover them up (a large sticker would not work...).. I was thinking of paint- but it usually ends up making the board heavy and uglier lol- I got a friend who does vinyl- but its not cost effective... could almost buy a new board! Plus Im expecting that he will distroy this board quickly since he is young and its his first board...
Any suggestions/ideas? Looking for something inexpensive and quick...

Emass... I think you're right. The amount of water taken in and how it effects performance is relative to the weight of the board. It's also relative to where the added water weight is on a board... like in the nose, or tail... bottom or rail... and also the rider's ability to even feel the difference; some guys do, some don't. I also think your right about water effecting flotation, but for the same reason I just mentioned, I think the percentage of "water weight" added to a board, and the location of that weight, that effects it's performance depends on what the rider can discern and/or tolerate. If a typical hpsb is about 6lbs, or about 96oz, and has a 4+4/4oz glass job, the glass job itself (resin and cloth) weighs about 1.75lbs. Substituting one of those 4oz deck layers with 6oz cloth will add about .25lbs, or 4 oz of weight, because the general rule of thumb is .25lbs of weight per 2oz of cloth on a typical shortboard. That's about a 4% increase. Can you feel the difference? Maybe... I know some guys can, and don't like it. Now imagine a ding that sucked in 4oz of water. That's a lot of water to absorbed by a typical ding, but if you consider a totally "waterlogged" board...
walkingonh2o... Embrace the ugliness! I have vivid memories of watching guys rip, back when I was a kid, on brown, ugly, beat up boards with duct tape hanging off them. Didn't seem to effect how they surfed. Besides... you know what they say about ugly chicks, right? Aside from that, sand the hotcoat right off, down to the weave, spray it, and hotcoat over it.

Thanks for the feedback...you must have seen the board! lol ducktape all over the tail and rail haha...old surf stickers all over the deck... I was thinking about sanding and glassing but didnt want to get too involved... will see... its really the right way of doing it. Thanks again!
