I have just broken my 3rd boge joint in 12 months after not ever having broken one in 20 odd years of sailing (I have replaced a few though).
I wonder what is the consensus, what is more durable a tendon or a power (boge) joint or is it pot luck?

I reckon tendons
- the material is just more dense
- there is no issue with swelling on inserts (in a Boge if the bolt corrodes and swells)
- the wide fabric strap on a Boge obscures some of it so harder to see cracks - plus is weaker than a couple of bits of downhaul rope as used for tendon systems
- tendons are usually easier to replace - if a boge bolt locks up it is hard to get tools into

I have had tendons last over 3 years, never snapped one.

i really didnt think anyone used those boge things anymore .. unless pulling their 20yr old gear out of the shed.

here is another reason ... they are extra heavy at 200g ...

i have used the north and neil pryde and streamlined for 20yrs and never had an issued ... and it doesnt hurt to skip a few meals at McDonalds and buy a new base every 2 yrs just to be on the safe side (as they are super cheap).
