True. When we launched our boat it had no rig. Fitting the rig and sails cost us about 3/4 knot in motoring top speed.

There's significant weight as well as windage.

At the time Passage Maker had an article by cat designer from Australia or New Zealand who was adding a flat planing surface aft of the rudders so I gave this guy the mag. Not sure if he ever added them but he did swap out the motors with bigger Yanmars.
Lightwave has a flat surface mold that they add to the standard Lightwave sailboat hull to improve its motoring capability. Don't know if they modify the rudders. It is a Tony Grainger design.

Ist vessel the motor sailer is a 47 lightwave with larger motors and shaft drive and the flybridge vessel is a Lightwave 38 with saildrives used as a charter vessel in the Whitsundays.

I assume the power version is faster. Do you have any of the performance statistics for comparison of the 2 versions. If just modifying the sterns, replacing the motors with larger ones, adding fuel tankage & removing the rig is what it takes to have a power cat that gets competitive speed I think
it might make financial sense to do this.

Even more than condo sailing cats the motor condo cats are probably the fastest growing multihull segment, at least in Europe.
