-Saw an interesting boat in the port today (I believe "Sunliner"?).Twin screw
with tunnels, fairly close to centerline. Props were about 18"-24" dia (was at
a distance) with "posthole digger" like pitch - 4 blade. Surprisingly large
squarish spade rudders.Don't have a clue as to how well she will twin screw on
her own, but doesn't matter as she also had a bow and stern thruster.
Boat was @ 36-40 feet, and I figure with that setup, even "I" could handle her
around the dock.-

Bilge- Bow and stern thrusters on a 40' boat? Twin screws and twin rudders?
Jeeze...that sounds like the setup we had on the CS Global Link.

I wonder if he has GPS-based staion-keeping software to orchestrate all those
components, on the "Global" class, our GPS "Iron Mike" could stay within a 10
meter circle on the bottom.

Downsize all that and put it on 40' vessel, and I wouldn't be surprised to see
the thing as Prima Ballerina dancing Swan Lake.

I saw a 40 for or so Mainship up on the St. Lawrence Seaway this
summer that must have had the same configuration. The boats captain
literally pulled up parallel to the dock and went sidways between two
other yachts that were tied up at the same dock.

Slicker that snot.

G You don't necessarily need a thruster or thrusters to do that,
though it certainly does make it easier.

I know - but this was so smooth, it had to be bow/stern thrusters.

Hell, his wife didn't even holler at him once!!!!

Take care.
