I've just crossed you off my list of possible Australians to ask to meet up with my boat... :D
At long last I got the motors and belt box running - I'm drawing about 5A with no load at 1500 prop RPM. I'm going to set it up with a power...
Aww cmon Rick, gotta break some eggs.... Working on installing running gear and then I'll ballast it with some concrete and do a "lake trial" to...
I'm not dead!! The hull is largely complete, as is the gearbox and propulsion control tray. This weekend Lonelybot is heading up to the "Maker...
Thanks! Believe it or not I've been paused on the belt box because the 90T timing belt pulleys I ordered were designed incorrectly! - belts fit,...
a) The concern is that, since I left space beneath the panels for airflow and the curvature of the deck, that when the boat rolls they'll be torn...
I sat down this weekend with an experienced sailor who's made the SF-Hawaii trip 7 times. His comments were a) my solar panels are going to...
Oh man, thats funny. To your original question, I'm no expert. To the first order, the most efficient prop would have long thin blades -...
I'm a little bit torn on the propeller, I'm not convinced a folding prop is a slam-dunk solution. I'm no expert, but I'm concerned about the...
I assumed you were speaking of some obscure and mystical naval architecture technique. The CATIA output is reliable - I weighed a sheet of my ply...
Oh, I was referring to motor controllers only (sorry, missed the "PMSM" acronym). Castle only distributes the Neumotors (they tell me) so they...
Rick yes it appears my code has an error when Roll = 180deg, which then my smoothing functions propogate into the nearby data. I'm fairly certain...
I'm not following you here. The estimate comes from the computer, yes, but from the solid (CATIA) models that I used to design the structure...
The CoG I posted was just a guess, but I do have realistic numbers from my CAD model: 13.5" to the CG (from the lowest point), 840lbs total. I...
I have Freeship, but I don't know how to use it [well]. I played around by dragging nodes until I have something that looked like my hull, and...
