I've got a bucket full of them and not one of them ever broke. Amazing piece of equipment considering the forces that get transferred through it.

Call me a n00b, but what is it?
It's the bit that attaches the mast foot to the mast base. Another type is called a boge joint and it looks more like an hourglass.
It looks like my finger after squashing it on the weekend hooking up some lifting chains - about the same colour too.

Oh, thanks. I just had a look at my mast base and see how that works now. I'd never really looked closely at it. It just seems to flex, so I guess they wear out over time? I thought they were actual mechanical gimbal joints.
I never would have guessed it looked like that when you described it. No wonder that uni felt dodgy.

Haha Ive got a bucket of broken ones, I'm now trying the north clear ones to see how long they last me or
maybe i should just stop sailing so much

Yeah I noticed that lovely clear north tendon at xmas.
I wonder if they break because you guys have them stored in a hot car with the gear i.e. heat effected whereas mine have never broken because they are only ever under a house (concrete bunker virtually) with very little temperature differential.

Vando,
On average, how many kilometres do you get from a Tendon?

Yer could be snags but no different to most people, not everyone has a concrete bunker 
.
John not sure km wise i would say on av 3 months sometimes less
God Vando, what are you doing to them? I get 2yrs from a tendon and replace voluntarily.
The gear stays in the car for most of summer so it sees 60deg or so for at least say 30 days a year, so dunno about Sausage's bunker theory

Sail more, break more... The one in the pic was new in October, so four months.

+1
I sail 4 times a week, mine last 2 to 3 years.
Agree with Gestalt, Vando you must suffer from tendonitis !
What I've noticed is that the ones that crack are the less frequently used ones, seems that they go dry and break. Whereas the ones that are on the water all the time seems to last for ages !
The Dodgy QLD water where Vando sails. Has to be. If he spent his time in the pristine surrounds of Pookipa he would not have any problem with tendonitis, the typhoid would kill that.
Back on subject I use the rubber unis as they absorb the shocks on PPB a bit better. Generally get 2 years out of them without a problem, in fact I think I have only ever broken 2 in 30 years of windsurfing.
Touch wood never broken one, never looked like breaking one.
Hot as all feck here in SA and on the back of the ute for weeks on end.
Lost more than worn out, I use chinook tendon that has safety rope built in for the unlikely chance it snaps
Out of interest are the tendons that have broken Chinook or another brand?
Here's a few from my bucket
I think they were Chinooks but how do ya tell.
Ive broken one first time out before, so I must be very unlucky maybe a bad batch.
anyway so far so good with the north one
yer swim saver ropes and webbings are too short and are distorting your feckin tendons!..where did your mother and i go wrong! ;)
Good point Greeny never looked at that. If the ropes too short transfers the load back onto the tendon rather than just bending.
I never touch the rope though from new but will check it out.

Posting at midnight p1ssed again Greenie . I think the distortion of the tendon is through continual load compression as there is no tension on the rope even at 90+deg.
Vando, The chinook tendons have fine concentric cirlces from the mould at one end of the tendon and perpendicular holes.
PS - my mum says hi too Greenleader.

Mine are Chinooks then
My tendon is fine... So is my cartlilage...Got a few sore muscles after last Tuesday....
Just replaced a couple, with Chinook. Nice tight fit in my Chinook base as expected, but quite loose in the other base (brand unknown). Are there different diameter sizes with different brands?
