OK purists ignore this post. Nothing nicer than a fully origional restoration although it seems almost every one I have seen is upgraded in some way. Concept here is what to do with that project that it really makes sense to gut the whole thing and start from scratch with a salvageable hull and cabin top. I have been bouncing this concept around in my head for awhile. Single jet drive under 40' dual or triple over 40' as they seem to be the way a lont of current yacht makers are going Jet manufacturers claimed benefits • Reliability, fewer moving parts with most major components inboard and out of harms way • Maneuverability, Split duct reverse bucket & JT nozzle combine for excellent maneuverability • Speed, optimized for speeds from 25-45 knots • Efficiency, meets or exceeds the best prop designs at speed of 30 knots or better • Shallow water operation, the ability to go where props simply can’t • Factory offices supporting distributors and dealers are located all over the world
Jet's generally lose about 40% of the power that is hooked to them, a propellor generally loses about 20%. Jet's are very very in-efficient at speeds slower than what the jet is designed to run at for efficiency and maximum thrust. Jet's are less reliable than straight inboards.....between sucking up debris and corrosion issues. If you're looking for better top end speed and efficiency, why not go with an Arneson surface drive?
Correct Answer For two marks. ARNESON: Arneson Surface Drives Advantages: 15% to 30% speed increase over conventional systems. 15% to 30% increase in fuel efficiency. Etc, etc,.... As you can see from lower photo, the conversion has been done before to conventional craft. Cheers! -Eric (plusyoucanripthegutsoutofanypassingannoyingpestsasterneh?)
Hi I think water jet is a good thing for our water archipelago is very shallow. I have looked at haminton jet advantages are many good maneuverability, low depth and at 25knop they are pretty good. Trans Auto AB | Hamilton Vattenjet [Hamilton, HamiltonJet, Vattenjet, Blue Arrow]
