Do you have a problem keeping them clean during the passage so it usable at the other end of the long trip?
Any structural issue when you're pounding into waves for 24-hrs at a time?
Not any more than any other underwater appendages, in my experience.
For crossing an ocean, however, I would consider blanking mine off. Not so much to reduce fouling as to reduce drag. It would be relatively simple to device fitted blanking plates with through-bolts.
No structural issues on a well-constructed tunnel bow thruster. I believe this even increases the strength of the hull
in that area.
Against the risk of leaks
, most well-installed bow thrusters are in cofferdams.
