There's a new range of 'superyacht hotels' on the drawing boards at Rainsford Saunders Design in London. The first, to be delivered in late 2008, is 9 metres longer that Platinum. Check out their website on http://www.aquiva.co.uk.
Greenline Hybrid is a boatbuilder that uses hybrid diesel-electric propulsion systems and solar panels on the hardtop plus smart design to make the efficient use of the energy on the boat. The result in some models: silent operation, full-size residential appliances, and an overall pleasant experience on board.
