Re: [PSUBS-MAILIST] Nice Report

[Ray Keefer <psubs2001@yahoo.com>]

Hmmm,

I have been thinking about Alec'es report for a few
days now. His details into towing, past experiences
relayed to the group by Gary Boucher, and Dan's
comments about using the thrusters are as good as a
tow boat. 

Gary said the sub tended to tow to either side of the
tow boat's wake. 

Alec mentioned controllabliby problems staying in
channels.

Maybe Kittredge had it right by designing a mother
ship to haul the sub to site. It is faster and more
sea worthy then a submersible. More controllable.
Unfortunately bigger and heavier. It is already
awkward to tow a 2000+ pound sub. A mother ship would
only work if you have a berth in a port to operate out
of.

I am guessing a mother ship is out of the question for
most of us. So how can a submersible be made more
towable? 

Bigger rudders mounted on the end of horizontal fix
planes in the back. The idea is that the rudder will
be more out in the slip stream and out of the subs own
turbulance wake.

As Alec mentioned, attach the tow rope as low and
forward as possible.

FMS(?) radios work in the surface? How about tying a
surface frequence hobby RC radio system into the
controls of a submersible. During tow just hit a
remote on your transimitter and the sub corrects
itself. No spam-in-the-can getting baked during
transit.

If you have to be inside the sub during transit. Could
some kind of water spray be set up to wet the exposed
hull to cool it?

Regards,
Ray
