Lobster boats are leisure motorboats with hull forms derived from the traditional working lobster boats of coastal New England — characterised by a high flared bow, low freeboard amidships, a wide open stern deck, and a round-bilge semi-displacement hull with a long keel protecting the propeller. The original form was developed for setting and hauling traps in the rough short seas of the Maine coast; contemporary leisure versions retain the exterior lines while replacing working interiors with cruising-oriented layouts.
The practical appeal of the lobster boat hull form for leisure use is its sea-kindliness in the conditions it was designed for: the high bow handles Atlantic chop without slamming, the low stern simplifies boarding and water-level access, and the round bilge produces a steady motion at displacement speeds. These are not fast boats — cruising speeds are typically 18–25 knots on planing variants, less on true semi-displacement builds — and they are not suited to extended offshore passages. Their appeal is aesthetic coherence between form and intended use, and a design character that production express cruisers do not offer.
Modern production lobster boats are built in GRP using vacuum infusion, with teak or wood detailing on decks and helm areas as a tribute to the original construction. Inboard diesel with shaft drive is the traditional propulsion choice and remains common; pod drives and waterjet installations are used on some contemporary designs where shallow-water access and manoeuvrability are priorities. Custom wooden builds from traditional boatbuilders in Maine and the broader New England region are produced in small numbers for owners who value the original construction methods.
