I am brainstorming on a boat design.  The basic idea is a solar electric trawler for one family
that has outriggers similar to those used for passive paravanes or "flopper stoppers" to 
help stabilize a trawler but a new active type.  These would look like little airplanes
or gliders.  They could use the tail fins to go up or down to increase or decrease the 
angle on the main wing and so change the pull on the outrigger as was needed to help balance the solar trawler.

A solar trawler probably goes slow like 4 or 5 knots.  This would be a rough ride normally.
If we can get a system with active paravanes we might be able to have a really stable
ride even at a slow speed.

If we are just solar, no fuel costs, and very stable it could make for a design that
people would want to buy.


Are there underwater rated actuators that could work for controlling the tail fins on our gliders?
How big would these be?
How much would these cost?
The line to the glider would have to carry power and data as well as a lot of force.

What sort of force from our glider would we need to keep the trawler very stable?

How big would the glider need to be?

At 4 knots how much power would be be spending on average to pull the gliders through the water
while they are actively stabilizing the solar trawler?

We could have a sensor on the lines so we know how much force is on each.
The computer on the trawler would have an IMU (Inertial Measurement Unit) and code to decide what to tell
each glider to do.

Does this seem like a plausible design?

I guess we could try it out with an existing boat and then when we went to make the solar
trawler we would know exactly how it could work.
