In theory we have a to say that it is a bit of both, it’s a power boat that actually mimics a shark, it is powered by a 260 horse power engine and it can reach up to 50 mph on the surface of the water and 25 mph under the water, yes this does travel under the water too!
The seabreacher power boat, can literally jump out of the water up to twelve feet into the air; imagine seeing that in front of you while you are having a little swim.
These are the features of the seabreacher shark body boat:
Re-designed shark style body
Mouth-shaped viewports for enhanced underwater visibility
Double snorkel intakes for engine’s increased air requirements
High performance, low profile wings and elevators
Powder-coated stainless steel and aluminium hardware
Custom exhaust outlet
Fully upholstered interior, customized to your desires
Front and Rear LCD screens, displaying live video from snorkel-mounted camera
Onboard stereo system with iPod dock
Removable lifting eyes for launching from a yacht mounted davit
