The Neonemo – a 42m (137ft) diesel-electric hybrid...


This avante garde-looking ultra-stable steel/aluminium explorer yacht project was conceived jointly by Canada-based naval architect Pat Bray and the UK-based stylist Ken Freivokh. They claim this already tank-tested semi-displacement hull form when slowed down to around six knots could be capable of cruising on battery power alone for up to five hours.

The hull is conically projected and double-chined with wide spray knocker and flared bow. It has been longitudinally framed for strength and ease of construction. Appendages include a bulbous bow, mid-ship bulbs, stern bulb, fixed/active stabilizers, and a bi-foil under each of her two controllable-pitch propellers.
Her range would be around 4,000nm at 14 knots. Her top speed would be around 16.

Powering Predictions – Project Neonemo...
6 knots: 2 x 45hp hybrid ‒ fuel consumption 0 US gal/hr range ‒ 30nm
10 knots: 2 x 158hp ‒ fuel consumption 15.2 US gal/hr range ‒ 8,200nm
12 knots: 2 x 288hp ‒ fuel consumption 26.4 US gal/hr range ‒ 5,600nm
14 knots: 2 x 470hp ‒ fuel consumption 42.2 US gal/hr range ‒ 4,150nm
16 knots: 2 x 843hp ‒ fuel consumption 74.3 US gal/hr range ‒ 2,690nm
