yeah I'd be interested in hearing about this also,
same story here, although my Carbon boom was the new slim C shape (more wave style really, super stiff, great boom)
I'm really copping RSI in front forearm/elbow, especially an issue when sailing underhand front grip (which is my preferred). Can't say if it's a directly linked or a not.. could be tennis, Gym, SUP related...but did all those in the past too, no issues.

Have recently changed to a 'wider more traditional shape' carbon boom as my go to, the C will be the infrequently used, will be interesting to see if there is improvement in the injury.. haven't been able to shake it all year, has really effected by 'boom' tennis serve! haha!

I guess there needs to be some give and flex? is it the same for knee's theirs only so much pounding before something gives

I have just recently developed tendinitis in my left elbow. I changed to a carbon boom in February and had sailed over 1600 trouble free kms since the change, so I don't believe the two are related.

Go To Physo, also known as golfers elbow.
I have it and now taking a couple of weeks off to sort it.
Not boom, more likely harness lines not it the right place
Mine started after a 100km + day

Golfers elbow, medial epicondylitis, inside of elbow with palms facing sky, tennis elbow, lateral epicondylitis, outside of elbow.
Can be "triggered" by various things, can be "caused" by other things.

I get golfers elbow on and off. For me it is triggered by a few aggravating factors, one of those is without a doubt skinny booms.

So did the injuries arise before

I have a chronic shoulder with rotator cuff issues. Been on carbon booms for two years and about 6000km sailed and have had zero problems.

I dont understand that you dont have problems yet you have shoulder issues, which came first boom or shoulder issues?

Did you have the tendinitis before the carbon boom? And now its gone since using a carbon boom?

^^^ seems like you are cherrypicking comments.
He said he had it before on alloy booms.

Then I think IKW777's post is fairly clear. He has shoulder problem/s but using carbon booms after does not exacerbate the problem/s.

are u trying to mount an anti-carbon boom campaign?

No maybe im thick, I just didnt understand the answer and was after clarification why would I be anti when I own a carbon boom., your reply didnt really add any facts which is what im after, yours was just an unhelpful opinion, and I see you do love to banter.

From what I have read on the Internet about golf and tennis on this injury, it has increased with carbon raquets and clubs and thicker handles reduce the symtoms just tryinv to work out if the same might apply to windsurfing.

Nope, it doesn't.

I got tendonitis a few years back on a winter vacation, when we got tons of wind on the first day after not sailing for a couple of months. It slowly got better over time, but stuck with me for 14 months. It finally disappeared completely when I discovered eccentric exercises - 3 days later, it was gone (details at boardsurfr.blogspot.com/search/label/tendonitis). I still use the same exercises a few times a year, when I feel that the tendon acts up a bit. It never gets to the point where it really hurts, though. I could probably keep it away completely by doing the exercises every week, but I'm too lazy. I sail only carbon booms, on average 3 sessions per week, often 80-100+ km per session.

Definitely try to find a good physiotherapist. If he does not use eccentric exercises as a key element, keep looking. I don't trust doctors at all with tendonitis. My wife had upper hamstring tendonitis, and her doctor did not diagnose it correctly at all. The usual steroid pills helped a bit, but did not make it go away. Once she figured out what it was and she found the right eccentric exercises on Youtube, it was gone within a few weeks, without any pills or surgery. In a clinical study where they compared the eccentric exercises to standard physical therapy for tennis elbow, they cut the study short because it would have been unethical to withhold the better treatment from the control group.

I'm no physiotherapist or Carbon expert, but I doubt if a carbon boom would give any extra problems compared with alu boons, i reckon Carbon would cause less problems if any thing.

we are not fully hanging into our booms, our harness lines absorb most of the jolts etc and we are pulling against the boom, not pushing our weight through it. So no shock/jolts travelling through our arms, shoulders etc.

With Carbon bike frames or carbon forks you do feel all the shocks/jolts through your body, same with stiff carbon boards, you feel everything going through your body. But booms we pull against and harness lines soften things.

just my 2 cents worth??

I'm not a physio a/hole but me thinks

I've been down the golfers elbow road, not a lot of fun, bloody doc said give windsurfing away for awhile, yeh sure. Started thinking about it and realised my troubles started after a mate talked me into short harness lines, like 22" instead of the 26" I used to use. I went back to 26ers and my elbow slowly came good, I now use 30"s and haven't had trouble for years. If you already have long lines just have a giggle and say silly old bastard

Just saying, uncle Bob

I agree Firie, harness line length is the key. The longer the better, keeps the arms straight and you control the sail with your hips instead of your arms. I just recently shortened my harness lines by a couple of inches. I'll now set them back at 30"

Injuries are usually from overuse or incorrect use of affected area. I have found with injuries that it is the user and not the instruments that are to blame.

Start looking at the things you do in everyday life. you'll probably find it's something non-windsurf related.

I think as Uncle Bob said "longer lines" and really load that harness.
