Interesting. I have often had similar concerns. These days, if I could afford an ocean capable boat, and it did not have active fins in good condition, then I would go for gyro stabilisation. The cost has come down quite a lot.

When I built my system I decided to be really simple poles go back not up. The arms only 10 foot long And everything can be retrieved by hand with a boat pole. I've been really happy with it.

On a new build I would install a wide centerboard trunk, and power a board as a vane would be .

A thousand years of CB trunk building assures a tight boat

and the usual CB kick up on grounding would be better than vane holes in the hull.
