I remember my Westsail 32 with it's unreliable two cylinder volvo diesel
. I could never count on it starting when I needed it. It always made me nervous coming in to port in marginal conditions or when there were reefs
close by. If the engine
quit at an inopportune moment, disaster could happen.
Having two engines was one of the reasons I liked my catamaran
so much. I always had a spare engine to prevent disaster should one engine go down. In fourteen years of ownership
and cruising around the world, I have never lost
two engines at the same time.
On of my friends had twin 38 hp Yanmars side by side in his fifty foot monohull cutter
. The twin engines were great when he lost one of his props in the south Pacific
If I had unlimited finances and was going the custom monohull route
, I would have one built with a dual engine installation
