Had an unexpected breakage this week. Chinook Pro 1 Carbon, 3 years old but only used about 10 times for light wind freeride days. Cruising along in 15kts and the tube snapped a few inches back from mast clamp. Out of warranty but have asked if they will do anything for me since its had so little use. Now did i just get a bad one or should i be looking to alternative brands. Cant post a pic as new member but its a clean break across the front tube with no impact damage etc.
The pic shows a nick in the EVA nearby, sure it didn't get a belting sometime (carpark drop?)
I repaired one and noted the step down where the clamp fits is a silly idea and they break right there so they're not my first choice.
But that break is very repairable. Just not fun making a curved ferrule as step1, but doable
The pic attached? The forum said i couldn't post pics...
I see the nick you mention and hadn't noticed it. Hasn't been dropped, id guess just from back of board when waterstarting or something... Im not sure where id go for a repair in the uk. Hoping Chinook might be able to send a new front end but if not ill cut it to look for voids etc.
My Chinook carbon medium slalom boom broke behind the boom clam after 2 years of reasonable use. I have a 10+ year old Neil Pryde X9 carbon wave boom that's still going strong.
I had a Chinook RDG boom break in almost the exact same spot. Was about a month old with no heavy use, in otherwise mint condition. They replaced it under warranty (6 months later...) and I immediately sold the replacement. Switched to Severne Enigma, much better boom anyways.
Which size is your boom? I had two 180-230 booms breaking. One in a bad catapult so definitely my fault, the other for no obvious reason, although it can't exclude that it was linked to earlier crashes. The second one was an easy repair since the break was further back, but it's now a 195-230 boom. But I also have two smaller Chinook carbon booms that have seen many hundreds of sessions without any issues (except replacing boom clamps on a regular basis).

Thats not good enough is it. I got 10 sessions out of it (?70 cost per use ??). Ive an old naish carbon thats been smashed about in the surf for years and thats fine.

Glad they replaced it. If i get any good will from them ill be doing the same. Heard good things about the new goya booms.

Its 160-226 so roughly the same. it has had the odd catapult but nothing heavy. I expected more from it.
So far I've broken Chinook, Goya, Duotone Platinum, Severne Enigma and S2 Maui. All were reduced diameter (far more comfortable than standard diameter) and all of them snapped in wave conditions. Right now I have an Aeron that hasn't snapped (yet, but I'll see what happens next time we get some decent waves). If the Aeron snaps I'll get either another Aeron or a Goya, whichever I can get cheaper. They are as good as any of the others I've used but usually cheaper.
If I was going to pay Severne Enigma prices for a boom again, I think I'd get the new North boom. Tried it once and it felt rock solid.
Both Goya and Simmer booms are made by Aeron so which ever you can pick up at the better price...
I've had a Goya (wave) boom for a while now, excellent boom. Used to see a lot of Chinook booms but not so many any more.

Heard of one snapping here too, very new.
Seems a weak design. My details have gone to Chinook to look at so if they are feeling kind I might get lucky with some warranty. If not I'll prob look for a second hand replacement. This was one of the few windsurfing items I've bought new (considering it a safety critical item).

That's good to know thanks. Only one one aeron boom before but was an alloy one and bendy as a noodle.

Oof, prob not worth paying top dollar then.
The 140-200 AL 360 boom that i have is maybe 15 years old and still feels super solid.
They are heavier than a standard carbon boom though.
I prefer my NP X9 of the same size as its 200g lighter.
The front end of the AL 360 has the best connection ever and the stiffness is next level.
If you are worried about durability they are the boom to go for.

Interesting, a carbon one or alloy?

They are custom carbon booms made in Italy.
They do an alloy line so too wondered. Look a nice bit of kit.
I have two of these booms, one broke for seemingly no reason ( likely an unseen hit or something). I fixed it watching this video and it has been going strong for a few years since. I bought a little carbon tube ferrule rather than the dowel approach bc heard concerns about water and wood swelling. Used that fishing shrink wrap to finish the grip after.

Here's my broken Chinook boom, I've seen two others broken in the same place (near the clamp). I heard they had some quality issues in the last few years. My sail shop got it warrantied for me even though it was over a year old. Good thing since Chinook does not even reply to emails about issues with their gear.
Here's a post about another one broken in the same place.

Well after a several weeks I didn't get anywhere on warranty but after a chat with the UK distributer they offered me a replacement at 50% discount so I went with that. It's a slightly different (newer) model and I'm not yet sure whether I'll use it or sell it. One observation is that the new Chinook looks suspiciously similar the the very inexpensive new MK booms. Like identical apart from the grip design ??

It could very well be identical; the boom I had that broke was a Chinook RDG with a different company's grip. Warranty went thru Chinook directly after I contacted the company I purchased from. I believe it's quite common for brands to do this with booms. That said, looking MK booms site, the lengths of the RDG is 140-190, vs 135-185 from Chinook, so maybe not the same in this case. Could be just using the Chinook head?

I can't believe you bought another Chinook boom after your experience and all the feedback in this thread unless you are planning to sell with profit. What are you trying to get out of your initial post?

I compared them side by side in a shop and they looked basically identical. Pretty sure it was a Chinook head and rear end looked identical but ?400 for the mk instead of ?650 for the Chinook.

Yeah I'll sell it on for a small profit.
To somebody who doesnt google chinoook boom durability / failure / breaking? 
Seabreeze threads rate pretty high....
I had a Chinook 180-240 show signs of about to break near the head. Several fibres had gone. After 330 sessions. I used it at 236cm length a lot on a 9m. Not surprisingly it wasnt the stiffest at the length, but was reasonably light compared to others. I bought another one, as the price was still fine. I've had it nearly 400 sessions, many catapults learning to foil. The longest setting is 230 on an 8.5m, which gives less flex. I've not used it so much at 230 as I use smaller sails foiling.
ps 1st boom I bought 2013, 2nd 2017.
