A great example of a family cruiser. With her center cockpit she is ideal for 1 or 2 couples.

She has a light and airy interior with an excellent layout. Her galley is well equipped. A strong Perkins 4-108 engine moves her through the water with ease. She has a full canvas cockpit enclosure providing year-round protection. Her shoal draft/centerboard configuration allows her to anchor close inshore. A great family cruiser or liveaboard!
