Jet Boat Performance Just a comment on performance. I have a 20’ Swiftcraft Explorer that weighs about 1500kg with an old AMEC jet drive and it...
Thanks for everyone's comments. However I would still like to ask baeckmo a couple of questions. You give an example of:- Effective power is...
Thankyou for you comments. You may be correct in thinking that variable nozzles have little to offer. I agree that there is much room for...
Interesting ideas. Very complex design though - I assume it uses pneumatic "diff-lock" actuator technology. My idea for a variable orifice is...
I haven't actually operated a boat with one of these units in it but the comments from the manufacturer when asked regarding steering and reverse...
This is a website of a small manufacturer near me (If you have seen the "Greatest Job in the World" promotion that is based on Hamilton Island -...
My comments are similar. Maintenance of jet drives is very minimal compared with every other kind of marine propulsion. Some units require marine...
Thanks for you comments - really appreciated. One more question - Can you provide me with the specifications of Navbus. Northstar/Navman won't...
I have thought that way - the Northstar has the hardware and evidently the software coded elseware in the PIC-Micro it runs on (or equivalent)....
That is correct. The silly thing about it in my opinion is that it does receive NMEA data from the Northstar remote GPS receiver, and the fuel...
My suggestion is to manufacture a low power CH70 transciever as part of the units. It does not have to be expensive, high power AIS or DSC radio...
Navbus - NMEA My Chartplotter transmits NMEA to my DSC Radio but the Chartplotter dose not receive the NMEA from my radio. The Northstar Explorer...
Low power (<1 watt) NMEA0183 format data strings on CH70 VHF (or whatever the marine VHF data chanel is in Danish waters) would appear to be a...
It seems different manufacturers can't quite make their products 100% compatible in this area and the sales people always say Yes, Yes, Yes when...
