Example of mounting for a 41 foot Apache catamaran

Uses our Universal mounting bracket.
This would be attached to the upper pushpit rail using a plate and U bolts, and the foot would be through-bolted to the deck. This effectively introduces a new vertical member to the pushpit which allows for the rapid attachment of the alternator yoke and also incorporates the upper tower clamp.
The bracket is fully adjustable which allows for easy alignment.

We usually suggest with catamarans that we supply a coarse pitch impeller for the water mode. This is because multihulls usually reach higher cruising speeds.
The standard impeller is optimised from 1.8 through to 9 knots.
