Mr. Vane or Y&B ?

my 20 ft. sailboat has a transom held rudder. do i want Mr. Vane or Y&B ? thank you.

For a boat with a transom hung rudder I recommend Y&B standard with an extra mounting tube.
This system has a mounting kit included that together with the extra mounting tube allows for mounting around and behind the rudder.

For fitting to smaller boats Y&B can be ordered with a short pendulum rudder, which is a free option.
