Large hp outboard on a tri

Afternoon.
Next boat will be a trimaran, but wife doesnt like me yelling at her when when the perverbial hits the fan
So, a compromise.
Thinking of fitting a 50hp high thrust to the back of a tri.
Issues anyone?
That way wife doesn't have "sail" as much.

 

Why have you decided specifically on a trimaran - and how big will it be?
Have you drawn up a particular statement of requirements for this next boat, and you think that a trimaran will be the best fit for your SOR?

What sort of situation is typical with your sailing adventures for the perverbials to hit the fan?
If you have a 50 hp high thrust O/B motor on the back of the trimaran, what are you hoping to achieve?
Do you just want to motor everywhere at (relatively) high speed instead of putting up the sails?
If so, and you are perhaps worried about manoeuverability, especially in tight situations (marinas?), then two smaller O/B motors spaced a reasonable distance apart would give you much better control?
It sounds like you are the sailor, but your wife is not?
If so, maybe the best compromise might be to get a power trimaran (or power cat) instead?
