I'm about to start a project on a 1989 Corsa Marine 41' (12 meters) with a pair of 540's & speedmaster #3, I could not find enough info. about these boats in the web, so I'll apreciate all the input you guys can give me here; pictures, specs, rough water riding stories, rig tips, or just your opinion on this boats, I'm all ears...

Given the age of your query (2009) and the date of my reply (2018), I'm not so sure you'd require any more assistance. But if you do, please respond back. I am the niece of the Performance Plus Marine owner/operators who manufactured that boat. Given the year of the boat, it is very possible I am the person who did the electrical wiring in your boat and may know it very well.
