Double Happiness 动力双体船

Sunreef Yachts delivered her in 2024 as a hybrid catamaran built around electric power rather than diesel, and she comes to market through Boatcrowd out of the Grenadines.

Build and provenance

She left the yard as a 60 Sunreef Power Eco, a diesel-electric catamaran with two 120 kW electric motors backed by two 150 hp Yanmar generators acting as range extenders. At 33 gross tons and with a 10.7-metre beam, she carries proper volume for a 60-foot hull, and her hull and superstructure are GRP throughout. Her engines already show 1,200 hours, so she has had genuine use rather than sitting idle since delivery.

Layout and accommodation

Eight guests sleep aboard Double Happiness across four cabins, with a crew of three looking after them. The primary suite sits aft in the port hull with its own larger bathroom, and three further cabins each keep their own ensuite. The saloon spans the full 10.7-metre beam between her two hulls, which keeps the guest table and the galley in one open room rather than split fore and aft.

Performance and engineering

Her propulsion pairs two 120 kW electric motors with two 150 hp Yanmar generators for charging underway, giving a cruising speed of eight knots and a top speed of ten. At anchor, the battery bank keeps her quiet through the night without a generator running, and her tank supports a range of 5,500 nautical miles between fills. For a buyer, that combination means long range with minimal noise, whether motoring or sitting still.

On deck and at anchor

A solar skin covers part of her exterior, adding another way to top up the battery bank without running an engine, whether she is under way or sitting at anchor.

Where she lies and how to see her

Double Happiness lies in the Grenadines. Boatcrowd sets up viewings out there and comes along for them, and once an offer is accepted, survey and sea trial follow before the sale closes. She also charters through Boatcrowd, so a week aboard is possible before you commit to buying her outright.
