Seaway 21 Seafarer

Seaway 21 Seafarer

Compact and elegant day boat

Seaway 21 Seafarer

A compact but elegant family day boat with overnight capabilities in a forward V-berth and an enclosed head. That’s Seaway’s 21` Seafarer. She’s just right for a lunchtime run to a waterfront eatery for a lobster roll or a crab cake, but her classic Yankee hull and self-bailing cockpit can take her outside with confidence. Mate her with a new-generation 115-hp outboard and she’ll cover miles comfortably at 15-25 mph with minimal trips to the gas dock (top speed will be in the low 30s). Add a full-width transom seat (storage under) and there’s room for three couples or two young families, with enough speed and power to tow water toys. A folding bimini provides ample shade and rain protection, with side curtains available for extreme conditions.

Fishing? Well, her layout follows that of the classic New England “bass boat.” Remove the stern seat and the cockpit offers plenty of room for trolling, livelining, and jigging. Add a bow rail and an anchor roller and it’s easy (and safe) to go forward to set an anchor. There’s space under the gunwales for rod racks, the gunwales can accommodate up to four rod holders. We can plumb one of the bases of the helm and companion seats for a livewell. She can even fish pots.  One 21 Seafarer owner we know, a resident of the State of Maine, successfully works five lobster traps on his recreational license (he drapes an industrial rubber mat over his starboard washboards for protection). The 21 Seafarer is a real head-turner. A choice of hull tints, canvas colors, and teak trim around the windshield and seats set off her lovely Downeast lines. She’s built to last, a boat a family can be proud of for years.
