Hi Guys.
I currently have a Euro pin Chinook base with bodge joint. Nothing wrong with it and it's been very reliable, but it's nearing 3 years old so I think it's time to replace it. I'm tempted to buy exactly the same one again, but curious to know what experience others have with different bases, such as Severne for example. Seems like there's not so many parts to go wrong with the Chinook. However, I noticed the Severne base has a couple of screws in the grommet... are these potentially a weak or corrosion point?
Cheers
Nigel

I'm a big fan of the Chinook 1 piece stainless steel pin setup after shearing off a screw pin a few years back (not fun).
Are those Chinook pins compatible with the pin type Severne or other companies use?

Pretty sure they are, only NP makes sure their stuff is not compatible with anything else

Yeah, pretty sure... it's Eurp pin. Not sure why anyone would use another system (rolls eyes at NP).
^^^^^
Yeah that's a bit ****ty.
And that tiny butten on NP extensions the size of a pea is also ****ty , it malfunctions even if u think of one grain of sand.
Go Chinook for base and extension and never worry about it.

^^^ +1
there is no other.
Yes, there is the Streamlined base:
Sorry the pin is still a separate piece and can shear off. Not saying Streamlined ones do, but seems every other brand does and that was the main complaint about euro pin.
Only Chinook has the pin and top cup machined from one piece to solve that issue.
Chinook also has slightly fatter bolts thru the tendon, every other system I used (plenty) bent the bolts a bit. Streamlined ones were hard to remove they bent so much. That was few years ago though...
Furthermore, the new Chinook has extra shallow, scalloped grooves in the pin to give sand somewhere to go to reduce sand wear / jam up.
Thanks for the replies gents. I was 99% sure I should go with another Chinook. Love their booms and masts as well. Quality products.
Sounds like I need the Chinook tendon base :) Happy days!
Don't start the tendon vs Boge hahahaha 
I say tendon as the Boge can have unseen wear between the strap and end washers, with tendon you can always see that the failsafe, which is a bit of downhaul rope, is still intact.
Other say the tendon breaks more (not my experience) but recently Chinook tendons breaking more it seems
I'd think if u replace every year ( tendon cheaper ) both should be fine.
If however your getting smashed in surf something has to give.
Better a bese than that new % 100 mast or carbon extension

I have to swap over to a Severne extension when my new race sails arrive. Unfortunately, the pullys are setup on an angle so my Chinook extension isn't ideal for use with Severne race sails. I was looking at swapping my base over at the same time, but wsn't sure about the quality of the Severne bases.
last week I was emailing to Windpower windsurfing in the US of A about Mistral bases for my old equipes. I recently broke an old bogie uni. The owner & staff all use the mechanical joint. He swears buy them for longevity & strength. Tendon; he says to replace every year. One point about the mechanical joint is that it is very easy to insert the extension.
Neil Pryde pin is very susceptible to sand. The cup is good. I really don't get why the europin is so popular.

I have NP base and streamlined, both pins are the same and totally compatible

Ive heard a harsher ride ?
I've heard that too. I have one, so I'm going to try this weekend. Can't imagine I will notice much difference on a raceboard....
Gastra base won't work with NP extension.
There seems to be a difference of about 1 mm from groove to base.
All brands are a little different.
This variance is a problem.
Some combos have the weight pushing on the groove , this is not good.
The weight should be on the flat and the groove only for the odd upward force.
When clicking in pin make sure base and extension are touching properly.
Thats my two cents worth

The twin pin cup thing - gets very loose, and the little button things shear off. I went away from them when I came in and only had one little button out of two, about 3x in 18mths. Sh!t scared about both failing....
I reckon I did something major to repair the base at least every season and the tendon bolts were always bent, needing heat to undo, stripping heads on piddly little bolts etc.
Never had a Chinook europin failure in 5 seasons on same base, can still easily undo the bolts in the bush if need be etc.

NP has just one (very big) button. Looks very sturdy to me

I use both Chinook and Severne bases with my Severne extensions and have no problem with the pins. I used the Severne base for years and only bought the a Chinook earlier this year after I had trouble removing the Allen nut to replace the tendon on the Severne. I had to drill out the nut and replace. I now use the the Chinook regularly and have the Severne as a backup.

I use a Severne extension with KA Race sails. The pulley on the sail and extension are at right angles to each other. This is not a problem as all it takes is a simple resequencing in treading the downhill rope.

sorry u mentioned cup (as opposed to europin) so I assumed you meant the old cup with two pins

No need to swap extensions

They are fine for flat water sailing, but terrible for the ocean.
As for the tendons, they can fail w/o a warning also, I've had them split where the pin goes thru inside the top or bottom collar, it's hidden. If the uni isn't standing up straight after you disconnect the sail, it is splitting at one of the pins, time to replace. But I have no preference over which to use, I use them both, however I'm a dedicated fan of a two bolt base going into the mast box. A single bolt can break the box in big surf, seen it too many times.

Same for me but for a different reason (don't ride in surf) : I carry a replacement unit in my hydratation backpack, no more swimming if the tendon breaks !!
Plus the base is always in the correct position (I have a base on each board)
Love the Chinook 2 bolt mast base. The best setup I have used yet. Very strong and durable peice of equipment.

But how easy is to to change the position in the mast track?

real easy as the bottom of the joint(check my pic) is the allen key for the base
This shows it a bit better, what looks like a bolt head inside the bottom is actually the allen key that fits into the base bolts, in other words, no tools required, the uni is your tool. Accept no substitutions, this can't be beat.
