We offer new ideas and concepts to boat building, giving boaters the best in high value workmanship, products and service. Location: Southern England Renato Levi Wrote three books on the subject of designing Powerboats. Best book currently available on powerboat hydrodynamics is Hydrodynamics of High-Speed Marine Vehicles, by Odd M.
If you are working in Aluminum, go to ABS, Lloyd's, or ISO and get rules for construction of high-speed vessels.
Jet boats are tricky, most major water-jet manufacturers have lots of data on what works, talk to the supplier. A phenomenon known as porpoising can occur if you are not caqrefull of what you are doing on the bottom, particurly in the 6' infront of the transom. Make the delta pad on the bottom nice and long, no-one says that the boat needs a 'keel', where the bottom sheets meet to form the vee.


Look at other jet boat manufacturers and what they do, we spend many hours making sure we get it right so we can sell a safe and well performing product. As has been said the key is power to weight and planing area in both laden and light conditions.
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
The merc sj175 does offer a reasonable amount of thrust, but the downside is that in their infinate wisdom, Mercury put the exhaust from the engine in the cavity between the hull and jet unit. I tend to think of those that do as 'old school', and perhaps we should scrap the shuttle and fly the appollo missions again.
As in aerospace, the trailing edges create a vortex, much like the tips of a wing, only in water that usually means that air is bled off, if that air makes it to the intake the pump will cavitate causing loss of thrust.
Visit our Boat page for detailed information on each model and available options for customization.


As I remember, they are nigh impossible to get hold of (you may have to order directly if you can find the website) but they are well worth reading. If you have a 'rocker' the boat will bounce around, or porpoise, if it has a hook it will bow steer badly, possibly causing the boat to spin in a turn.
Look at not only straight line performance, but also where any vorticied will end up in a tight turn (if you terminate your strakes ahead of the intake), if the unit cavitates during a turn and you loose thruse, a real nice jet spin often occurs, sometimes at an inconvient moment!!! With a Exact welding custom river jet boat you will find yourself sight-seeing in the northern back country with more confidence. By adding a camper top you can enjoy overnight camping adventures in the remote wilderness.
