I never thought about if we need it or not, before. Interesting and good info from Dan W. And interesting that Nevin decided to put grip on Fiberspar carbon booms, for marketing reasons... even though testing, showed it wasn't really needed. That was a long time ago, and Nevin probably made the right decision.
For the first 30 or so years of windsurfing, all booms were alum. So, they gripped boom for good reasons - it's warmer... it's way better for grip... and it keeps the alum from getting dented if rigging on rough surfaces, etc.
Now we have a combination of alum and carbon boom. And I can see what's being said, about leaving carbon booms bare. They're not cold on your hands like alum... and you could add a little texture like Dan said, for some grip.
I'd still wonder about durability though. Doesn't the boom grip provide protection to the carbon tubes... from rigging on rough surfaces... or accidentally banging them into something??
I know we've always been told, be very careful with carbon masts... don't let them bang into rocks and hard things... you can cause damage to the fibers, which can lead to breakage.

PS - I like the tape ideas, and also have a couple booms which only have certain little spots where the grip is gone or loose. Wrapping that tape around for a few inches sounds just right. Simple, effective, quick and cheap. |
Carbon booms are not carbon masts. Booms take a beating on the board and in the truck. I can't say for sure but I'd guess that most carbon booms are no more than about 75% carbon in the main tubes. I could be wrong. What I do know is that carbon boom arms are thick-walled and very, very durable. A thin layer of foam doesn't add much protection to the boom at all, though the grip certainly protects the board a bit.

| Speaking of durability of carbon fiber, I have a fiberspar world cup mast that I somehow managed to run over with my truck. The rear tire ran right over the base of the mast putting a 4" long vertical crack in the base. I thought It's ruined! throw it out! but I could not, after all this thing cost me some serious change! The base was still round, I could insert a mast extension so i thought lets try wrapping some fiberglass saturated with epoxy resin around the base extending an inch or two above where the crack ends. Worked like a charm. I'm still using the mast, the repair was done 25 years ago. |

Dan,
I guess "thick-walled" is a relative term, but I have an old Fiberspar that I'm getting ready to repair with a carbon tube insert and some carbon fiber sleeve material. The tube OD is 1.225" and the wall thickness is 0.069" . I thought they would be thicker-walled than that - looks really thin to me. This is an oldie, so I don't know what the newer booms (with smaller ODs) are.

Hi Thombiz,
Do you not sell boom re-grip kits? I know you did once as I purchased one from you and I was very satisfied with it as well as the instructions that you sent with it. It is some work and I am sure I would do better the second time I did it, but the first job is passable and still being used.

| Yes, I used to sell regrip kits, but I no longer sell them. It goes something like this....I only sold about 6 to 8 kits per year. I made about $10 per kit. People would complain about the price and try to beat my price down. They didn't know that the adhesive in the kits had a relatively short shelf life and I had to buy it in 12 packs so I would loose about half of it to shelf life every year. Then shipping was a problem. I would spend $4 in gas to take it to the FedEx location, so profits suffered. Pretty soon....it wasn't worth doing. Yes...the grips were the best I could find and the ones on my own gear are now 5+ years old and doing great! No profit means no business. |

Understood.
I want to thank you for selling me mine. I thought it was an absolute bargain.
You now have given folk a multitude of other options in you posts above.
Good soul, you are. |
