Kevin since you seem to know about the Streamlined, any solutions to offer for the above described problem with sand from the surf jamming the release button of the 2 bolt deck plate? It is impossible for me to release with just my finger(s) on the beach when this happens. Which happens just about every long session or every other short session in the ocean. Thanks

Has anyone had the Chinook single bolt attachment come loose ?


Yes. After mine ripped right out of the deck box in a new high-end board in 1992, I switched to their twin-bolt design to spread the load better. Haven't had a problem since.

Hi Kevin,

In your explanation about Streamlined's optional plastic disc, you mentioned that it has a mast track center post. I'm not really clear about this. Is it simply a hole in the center of the disc, or is it a physical feature that has been molded into the design?


The disk has a post on the bottom side that goes in the mast track and keeps the disk from spinning. It also aligns the horizontal reference line so you can use the mast track measurements on your board. Here's a pic of the underside.

Hi ctwindsurf,

I mostly sail in non-sandy places... we have more rocks, wooden piers, and asphalt around here, and I mostly use the 1-bolt unis. When I did use the 2-Bolt Streamlined unis, I never had a problem, but Crissy was really our only sandy spot. My masts sometimes get stuck, but I never had my baseplate seize up.

As always, Kevin, you do a great job of being very responsive and presenting the details so well.

As one might say, the real bottomline is in the details.

Yes, for some reason the Streamlined Twist-On universal joints don't come w/ a plastic disk, and using the uni without one does make tightening and untightening much harder. Streamlined does make an excellent disk that is clear, has a mast track center post, and has a horizontal line so you can line it up w/ the mast track measurements that are printed on many boards these days. The downside... they cost $10. I usually sell them for half price if somebody buys a uni, as I think they're important. Or you can just use the regular black plastic disk from your old uni.


Hey Kevin

Do you have the streamlined in yellow anodized ALU? I'd hate to break up my perfectly color coordinated kit. BTW: what harness & lines do you recommend? LOL...

an old CD or those free software discs they used to mail out work well for a baseplate. i;ve never had a problem with chinook single, but usually use a two hand, actually two thumb,technique to get it tight.

I would also point out that the bolt of rubber mast base from Chinook (not the tendon) is not in the center which makes using the plastic disk (washer) impossible. The rubber bases are great when you are learning to waterstart but might be the one from the original post that is coming loose. Once you aren't learning to waterstart or falling a lot switch to a tendon base.

So I have a new sail that requires a 4cm extension but all US base extensions have a min setting larger than this. So I realize for the first time that one advantage of the Euro pin is a smaller min setting. Is there any thing else I don't know about one vs the other. I am considering switching to Euro Pin Streamline gear.

I find the tendon bases tend to ride stiffer.
As for power transfer, I feel there is little difference. I competed in years of speed trials sailing, have tried the mechanical bases, and feel rider ease is what makes a sailor go fastest.
One year, at Kailua, sailing with the slalom crew there, I'd lead the pack and for some reason, nobody could pass me. I was on a Haut 8'10"er. My uni had stretched to well past the rail of the board, on either tack. It made no difference in board speed. And no, it didn't break.
