I've wondered about the feasibility of purchasing a 32'-38' sailing catamaran and removing the mast and sails to sell (hopefully offset the purchase cost somewhat). Even used power cats are always so expensive but more older sailing cats to be found more reasonably priced. I realize that power cats have different hulls but the sailing cat sans sails should still be pretty darn efficient and loads of room for a liveaboard. If one could repower up a bit to have a frankenstein trawler cat that would be efficient at low speed (trawler-like gph) but have some 'umph' when you needed/wished to go faster, too. A poor man's power catamaran, so to speak. I wish I knew where to find info on doing something like that. Anyone know of a blog of resource of anyone that has done that or documented attempting?

The OP is gone, I think, so feel free to bash me now instead. Thanks.
feel better now?

You have MY permission to do what you will with any boat you wish to make into a power boat.

It is feasible and very affordable until you try to make them go fast. Most sailboats, even cats have "displacement" type hulls and tend to build dam like wake as they are pushed beyond the theoretical hull speed. Applying more power beyond that makes them churn the water and actually ride lower in their own wake even go slower.

You could get lucky and find some that will plane like some of the high end racing sailboats. but I'm really not an expert on all this. There are some very well qualified naval engineer/ architects here on the forum that could help on that.

I don't think you find much about making sail into power because it's all a very low tech way to make a power boat. Purists won't be much help. Motor sailers, even some trawlers have sails to compliment the power of the vessel, and to not have that available is a real loss in the vessel's actual design. Power boats do go better with power; Just the way things have evolved in boat design. Sails and wind pressure (there is a formula) can be converted to horsepower AND it's amazing how much power sails really do develop! It's way way beyond what just a motor can do because "lift" is also part of the equation.

"motor sailing" (Usually jib deployed and motor running) a method many of us use to make way in good time. This can't be done if the "new" boat is without sails, end result; it will motor slower then if it were "motor sailing"

This "make a sail boat a power boat" really is nothing new as some people just never bothered to raise the mast and or sails.

ps I only really read what you just posted.
