Agree with JRD, I had a 36 foot heavy displacement boat
with a fair amount of windage, single screw. It was a handful
when docking in cross winds, many a time I wished I had twin
screws. Even in steel, converting to single screw sounds like
a massive project, new log shaft and rudder, possible re-configuration
of the keel, and what else?. In addition to the docking advantages
having two engines and charging systems would seem good to me.
The boat was designed for two engines, changing could possibly
upset the overall balance and performance? If you want different
engines for whatever reasons change them out. If it was my boat
I would stay with two engines.
Just my two cents worth, Dabnis
Fair points - our biggest concern was the inherent Perkins leakiness and extra space that may be gained by only having a single screw, but having tried to dock a 34 footer before with a single, having two would definitely be much easier.
If we were going to stay with the two then and wanted to repower, Universal? Yanmar? She's a heavy boat that won't use the engines much but when they are required, they'll be put to hard work (European tides). Any standout manufacturer we should be looking into?
