ok here is the situation,

my board
mates 9ft board
roof racks
car

car driving on open road, at open road speed.boards are facing tails first.large gust of wind(blowing head on) gets under boards and lifts the front, then rips them off (roof racks and all still strapped together).boards go up in the air turn up side down land on road behind the car, then come to a stop off the side of the road, with my board on the bottom and 9ft and racks still all strapped together.

so how bad would ppl expect the damage to be after this?remember the weight of both boards as well as the racks, hitting the tarmack at somewhere near 100k.my board making contact with the road and no damage to the other board.both boards in bags.

damaged sustained, fin damage and one section of the rail.
Has anyone else had and accident similar to this and able to share their experience and photos?
i was extremely relieved when i checked my board over, especially knowing it was the point of contact.

 the surf was *****ing btw, so wasnt all bad.

Thats a lucky escape bro!
Or maybe you made your own luck by building the board right  Smiley

I've never had one come of the roof, and i'm not keen for it to ever happen!

I guess what im doing with this thread is raising the question of durabilaty wrt composite constructed boards and whether or not this is evidence of that.

Hey Hunty,

Just caught this thread.  This is something I've thought about quite a bit.  I've build 5 boards total.  1 hws cedar w/o glass, 3 full balsa compsand, and one 2lb eps/hand layup epoxy/glass.  Oh, and I stripped a broken board and laminated it with epoxy/hemp using a vac bag, after putting it back together. With this limited experience, in addition to my poly boards, here's my assessment:

The epx/epoxy board was the worst for durability.  The hemp board wasthe best.  I dropped that thing so many times, banged it on the rocks, etc, hardly a scratch. But it was heavy; well, about the same as a poly board.  The balsa boards have incredible impact resistance to blunt force, and surf the best.  But ding a rail on the rocks, or anything sharp, and it may as well be poly.  I've spent many hours fixing my balsa compsand boards, but I love them.  I think what Paul says about balsa rails being crappy for ding management is absolutely true, but the boards work and I'm not selling them so I'm happy.

My guess is that the fact that you had the board in a board bag is what saved it.  The bag would have prevented all the good old road rash effect from tearing through the glass, and the damage you saw was essentially the blunt impact damage.  It's a good construction method, that's for sure.

Just my thoughts on an old thread....

The picture of the fins brings back memories...

Back when I was in high school I had gotten my first custom surfboard, a Pat Ryan E.T. Surfboards "stinger" (that will give you an idea of the time).  We used to meet at the 7-11 at like 4 in the morning and skate down to the beach.  In the dark I hit the proverbial rock, flew, and then "belly boarded" my surfboard for about 5 yards on the asphalt.  Total damage was a few scratches, one small ding where the leash pushed into the bottom (anyone remember the 'zing string' surgical tubing leashes?) and a ground down fin, just like the ones in your pic.  Good news- the fin grind didn't affect performance.  I'm not sure with the pro core, but I think that material is hydrophobic.
