I'm looking for a urethane mast tendon for an old Ten Cate Runner windsurfer - circa 1985 - looks like

Can anyone point me to where I can find such a replacement part?

Is this serious ???

you should definitely found one at your local sexshop!

hi netless

i had a TC RUNNER recently and It didnt have a "shlong" like tendon ..infact it had a normal "boge" joint as available from any shop for around $30
I remember this as I replaced it with a new one.18 months ago[dont have it now though]
I have thought though another owner said he had a different mast base to mine.

perhap the previous owner had replaced the shlong setup with the boge setup on mine????????

i remember the Runner had a mast base that was a large plastic locking device that i think had only 2 positions ...it was rectangular with a locking clip,and located in a matching recess in the boaRD
utop of this base was the standard type "boge" type tendon bolted to a mast cup.I have a feeling this may either be a later design or a retro fit.If you could send me a photo of your mast base I could at least give you an idea as if a simliar type of conversion could be accomodated.
If your base has a bolt out of it or a hole to take a bolt and nut through it it should be easy to purchase a mast cup such as an old hydrodynamics and bolt a "boge" joint to them
I presently am doing a "boge" retrofit to my early mistral as its tendon although rubber wise is good has parted company with the metal ends due to salt expansion between rubber and steel.

depending on your mast base a solution may be simpler than finding the "shlong"
cheers rusty

Hi Rustbucket. Thanks for your reply(s) to my TC mast tendon problem. The mast step is exactly as you describe it - see photo -



The mast end has a round ended cylinder with a similar hole for the tendon.

I like the idea of a conversion to fit a currently available tendon, but I'm not sure of what the "boge" fitting looks like or how it may attach to my existing mast step. Any chance of a rough sketch of what your setup looked like.

PS I have the original TC sail in good order (I'm the original owner) so I don't have much need of another sail - or probably anything useful to swap with you - but thanks for the offer.

Sorry netless was away sailing up the central coast
just got on today
yes that is exactly what i had
so get yourself to your local windsurf store and buy The "boge" joint from West Germany...it is the common one sold here in sydney shops for $30 roughly
what youll need is to use a long stainless steel bolt in the mast cup long enough to extend out the bottom to tighten into the boge joints thread,inside the mastcup a large washer come spacer to fill the cavity of the internal cylinder to take up the slack of the difference in diameter of the internal tube and the bolt.
use a hydrodynamic yellw boge spacer to be the bases bottom washer bolt all this to the boge or perhaps even hydrodynamics version which itself maybe the same brand anyway
On the bottom bolt boge to the cicular cup with a yellow hydrodynamics spaCER between and an appropriate bolt and nut setup
if i remember rightly the cicular cup still took the boge well or make up a plate to eliminate any circular discrepency.

The boge looks like a rubber hourglass with a threaded hole either end ...i think can be opbtained in two thread sizes.
it is about 3 inches high and 2 inches wide.....indeed very common for sale in most windsurfing shops

you may neeed to make adjustments to get a good fit,obtain a long stainless steel bolt from a proper nut/bolt shop and you may need to cut it to size to get the correct fit as in reality it is the threaded bolt topping out in the thread that holds it tight,and this can come lose if you dont top it out,alternatively use a long open ended threaded bolt without head to use a nut with plastic lock on top so the threaded bar has already been tightened before fitting only relying on the locknut to hold it together tightly.
sound complicated but my only trouble was finding a long stainless steel bolt
hope this helps
if you are in sydney you arwe welcome to come see me if you are having problems
