<div>Have you guys seen those Catamarans in the America's cup ? Quite amazing. They use the hydraulics to move the foils up and down as well as moving the "sail" or more correctly the wing. It's all they can do to keep up the hydraulic pressure for the constant adjustments that have to be made.<br />

<div>Just did a quick google & there are hydraulic rim bicycle brakes as well as the disc brakes.</div>
<div>These look like they could be possibly adapted.</div>

The problem is the caliper has a rather large piston area. This gives you better brake force, but it would hurt you when you put water pressure against it. You want a small piston like a hydraulic clutch in a car. I would use the clutch parts because they would also be aluminum and much tougher. You would need to remove the piston and machine an o-ring glove because the normal seal is designed to push in one direction only.</span></div>

Hi Brian,<br />
I've wondered about this also.<br />
I was looking at the hydraulic brakes they have on bicycles now days &<br />
wondering if you could adapt them for functions like releasing emergency<br />
bouys or similar. The manual hydraulics they have on boats, like steering units<br />
are pretty expensive. Would be good to find something of suitable material<br />
off the shelf hat could be used.<br />
