Bow Thrusters on Ocean Yachts

Question to those that have bow thrusters and are out on long ocean voyages.

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?

No experience personally, but we've had extensive fouling from gooseneck barnacles on long passages... even on topsides submerged due to heeling. I'd sure be surprised if a thruster would not suffer even more.

Re: Bow Thrusters on Ocean Yachts

The internal one (one that is lifted into the boat) suffers no fouling.

The external style gets minimal fouling if prepped properly prior to the passage. Whatever the condition, they are powerful well enough to mash whatever grew on them underway.

Re: Bow Thrusters on Ocean Yachts

I've heard of the one boat that had their thruster come down in a seaway, twisted, then couldn't be retracted again, had to retire from the ocean race they were in. So if I had one of those ones, I would look at securing it in a seaway so that couldn't happen, but then also remember to remove the securing device before using it, but then again, I would be sure to forget!

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.

Ours is in a tube. No issues whatsoever offshore.
