I am not surprised that you found the Bruce to be unreliable. We had one briefly in Greece and soon discarded it. We found that it would not cut through weed and when it had set, it would not reset when the wind came from another direction. We also found it’s spoon shape to have a major disadvantage, for it’s tendency to spoon up boulders – you try lifting your anchor, chain and big boulder – we had to call for outside help.
I understood the Bruce to have been designed for use on oil rigs, where it was fine, but a fixed platform is no comparison with a boat!
We changed then to a Delta, which was fine, but we find the Rocna is superb
I notice that you have a Kiwi prop fitted and find it works. We too considered this, but felt the engineering quality of the Nauticat did not go with a plastic prop. We therefore have fitted a Bruntons and since our boat is in Greece and it was fitted over this winter we have not yet tried it out. We went that direction, as my son has fitted one to his Bavaria 42 (also in Greece) and it literally has revolutionised his boats handling. Going astern is longer a lottery and for stopping one almost needs safety belts on.
