After Dutch designer Maarten de Bruijn bought the rights to Spyker name, the first prototype design he attached it to was the Spyker Silvestris. A couple of years later, he and partner Victor Mol had Spyker making cars again, but in 2005 de Bruijn left the company for other pursuits. That same year, he and two other partners founded Silvestris Haute Motive Concepts, with the first product being the 23-foot Silvestris Sports Cabriolet speedboat.
Using automotive build techniques - hence the name "Aquamotive" - aluminum panels are bonded and riveted to a tubular aluminum spaceframe. The cockpit features a tilt steering wheel and heaps of seawater-proof leather. The remotely-controlled rear hatch hides two more leather-shrouded thrones, and even the front compartment comes with a hatch (making for a markedly sleeker-looking craft when closed). There are six engines available, the uppermost being a 560 horsepower, 8.1-liter V8 good for 55 knots and more than a few envious looks. Check the Silvestris out in the gallery of high-res photos below.
