In this sector of the market, monohulls are still leading the fleet for the time being... but smaller power multihulls - mostly catamarans - are convincing more and more builders in the United States and Australia thanks to their stability, both when under way and at anchor. These ‘multipowers’ are most often propelled by twin outboards, whether gas or electric powered. Accessible and easy to handle, these compact multihulls allow day trips, fishing and, why not, from 16 or 17 feet in length, a bit of coastal cruising.
Overboat - (Electric) foiling for anyone
Test in MW#176
This modern and futuristic pocket catamaran allows anyone to fly above the water thanks to its four electronically controlled and automatically adjusted foils. These retractable appendages make it easy to leave from a beach or a pontoon, and return to your starting point. The Overboat is capable of a top speed of 15 knots thanks to its 4.5 kW electric motor in the single-seater version. At 12 knots, there’s enough power for 2 hours. The Overboat, which is classified under category D, passes very well through an 18” (0.5 m) chop, which is quite rare for a boat of this size. A “Classic” version, without foils, is also available.

Ballistic 5000 - A cat for fishing and day trips
This mini catamaran designed for fishing - and of course day trips – is offered by Australian builder Spirited Designs, a specialist in multihulls in kit form. Delivered at any stage of completion, the Ballistic 5000 is very light thanks to its Divinycell/epoxy foam sandwich construction. As a result, this little catamaran can be powered by smaller engines, and is easily transported on a trailer. The deck layout is clever: the entire surface area has been exploited, thanks to a full deck at the bow and a platform at the stern. The helm station and cockpit are perfectly protected, and the superstructure houses a mini-cabin.
Builder: Spirited Designs
Length: 16’5” (5.00 m)
Construction: Epoxy sandwich
Motors: 2 x 50 HP outboards
Powercat 525 - Small but tried and tested
The test videos of this pocket powercat leave no doubt about its seakeeping qualities: the machine jumps from wave to wave and always seems to be at ease, whatever the sea state. For all that, the designers are not looking for power overkill - 2 x 30 to 2 x 120 HP. The maximum speed quoted by the builder, subject to the chosen drivetrain, ranges from 16 to 30 knots. The deck layout comes in several versions - open, central passage, cabin - and can accommodate 7 people.
Builder: Powercat
Length: 17’3” (5.25 m)
Beam: 7’5” (2.25 m)
Draft: 11” (0.30 m)
Light displacement: 1,300 lbs (590 kg)
Motors: 2 x 30 to 2 x 120 HP

Castlerock Carbon Cat - The temptation of a rib
![]() |
Designed in Australia and built in New Zealand, the Castlerock Carbon Cat was designed by Dan Oatley, a member of an Australian family well known in the boating world. This catamaran RIB is built from an aluminum chassis and a carbon deck. Trim is controlled by a pair of trim tabs. Although this boat’s short length confines it to relatively sheltered waters, the top speed recorded with a modest 115 HP is still 60 knots… We can only imagine ...
