Extreme Flats 20
Designed by Jacques Mertens
A 20 ft 4 in tunnel-hull flats skiff by Jacques Mertens of Bateau, worked out with flats fisherman Ken Owens as an enlarged GF16 garvey with a tunnel aft. It is drawn to float in almost nothing: hull draft is 2 in at design waterline, with an 8 ft beam and a hull weight of about 450 lb. Power is 25 hp with a 50 hp maximum.
Plywood cored epoxy and fiberglass composite, stitch and glue, offered with or without a sole. The designer says it can go together in a few weekends if kept simple. The designer's figure is 30 hours for the hull and 80 or more for a finished boat. The medians below come from builders who logged this boat here.
What building a Extreme Flats 20 actually takes
Medians from the build logs kept on this site, not the designer’s estimate. Nobody has logged this boat here yet, so they are empty until the first builder does.
Those medians firm up as more people log this boat.
