I got mine last year and did quite a few changes to her already...
I added insulation in the saloon area (crucial for living aboard the chesapeak bay during winter), added Solar panels (I put a SS pole between the first stanchion post aft and the rail on the stern and put the panel on a swivelling mount in between). Also I ripped out the carpet on the hull inside in the saloon area (where the "shelves" are and built some proper shelves in there with nice fiddles and a second level added as well of some of them with locker.
Then I added a Windvane for more comfortable cruising along the coast and ultimately for the way back home to the med and so far the biggest Project:
After my Yanmar died I replaced it with an electric inboard engine, which works beautifully! Love it so far!
All the changes, modifications, pictures etc can be found here:
Hope it helps...
