Effect of large keel on Disney NAUTILUS

[modelnut]

Just a thought...

Does that rather large keel on the Disney NAUTILUS have any effect on the boat's handling? Does it detur steering? Or does it fight the torque of the propeller and keep the boat on an even upright in turns?

Leelan,

I can only speak about the NAUTILUS MINISUB here.

My keel is solid steel and pretty thick; has extra plates for additional weight, also. The intent was to ensure positive dynamic stability in the upright position. One advantage of a whoppin' big keel is the boat tends to stay dirty side down.

Does the keel deter turning capabilities? Probably somewhat. I mean, she doesn't want to wag her tail from side-to-side much at all. Turns like a train]http://www.subcommittee.com/forum/icon_smile.gif[/img]

That is what I was thinking. But thought experiments don't stand up to real word experience. So I thought I would ask.

Hmmm...

I guess the keel would negate the effectiveness of a small outboard propeller*. I've heard that modern subs have them for manuevering in tight places without a tug.
