Tombolo 28 Outboard Cruiser

As the Tombolo name describes, the design is intended to be a bridge to the islands. The goal was for a summer cruiser for two, with occasional day guests, that could easily speed out 15-25 miles to a quiet anchorage for the weekend. It isn't intended to be a shiny, precious boat, but one that sandy feet and crab pots are frequent. She will get laid up come late fall and stored on a trailer cheaply until the following spring, or perhaps even trucked to a distant port.

The mission of the design was to create an accessible and attractive powerboat under 30′ with a trailerable beam. The low weight and modest horsepower allow one to cruise economically at just under 20 knots with a minimum of fuss. The Tombolo 28 hull form is an easily driven modified-V, low deadrise hull with a fine entry and long waterline. This hull has been optimized for a single outboard motor in the range of 115 to 150 h.p. maximum, which will meet a cruising speed of just under 20 knots, and can be driven to 21-24 kts.

Main Features

  • Simple light-weight construction
  • Efficient modified “V” low deadrise hull
  • Low cost single outboard power
  • Large Cockpit with lounge and table
  • Open transom with boarding/swim platform.

Description

The arrangement is geared towards a large convertible outdoor space with a hardtop overhead for shade from the elements with a removable canvas enclosure. The helm is forward with dual chairs and a small galley to port. Aft in the cockpit is an L-shaped lounge and pedestal table. The lounge backrest forms a boundary to the moterwell aft, with a door to access the swim and boarding platform.

Entering the cabin through the companionway forward of the helm, one descends a couple of steps to the accommodations under the raised deck. The private head compartment is to starboard and drawers and lockers to port. A generous 6'-6" long v-berth is forward with ample storage underneath. An optional bow thruster is also under the forward bunk, which makes single-engine maneuvering simple. A watertight bulkhead separates the accommodations from the rope locker.

Ultimately, this is a very versatile design that can adapt to many cruising grounds. Small powerboats seem to have an increasing allure to those looking to easily get away and overnighting. Though not intended as a speedy offshore battlewagon, it's well suited to coastal waters and lakes. Kayaks or a 10' inflatable stored on the hardtop allow for gunkholing and exploring harbors. The cockpit is large and accessible enough for fishing and crabbing as well.
