"I am no expert but take a look at http://www.mbari.org/data/mbsystem/
I understand that it can accept sidescan data but doesn't do a great job of overlapping imagery but you can use http://www.osgeo.org/ossim to do this."

"I may have found a place here to construct my boat. Yours, however, looks like it is almost ready for the water!
I have been thinking more about the design here:http://www.faymarine.com/plansite/images/1_SS_aux_rudder.GIF
The 'course setting'…"

"Yesterday I headed to the coast to find some boats with wind-vanes and to find somewhere to build a boat.
No luck with finding wind-vanes, but I may have found two places to build a boat. And topped-up my sun tan :)
I have a couple of hours free…"

"So, the problems with a wind-vane is that it requires careful setting, and it is susceptible to water coming over the bow and hitting it (this latter problem obviously does not affect yachts as the wind vane is several feet higher).
And the problem…"

"After reading some more things and writing to people, I'm less convinced that a linear actuator directly controlling the rudder will be the right tool for the job. It's probably too many actuations. The idea you suggested earlier, re: self-steering…"
""Give me a lever long enough and a fulcrum on which to place it, and I shall move the world." :)
I am hearing a few bad stories about tiller pilots failing, and I am trying to work out why as they are very similar to what I intend to build. I don't…"

"Hello LoopZilla,
There are some interesting underwater drones out there, mostly torpedo shaped. I think one of the most promising is one that uses changing bouyancy to glide through the water at about a 45 degree angle, both down and up.
My main…"

"You are right about the lifetime of the actuator being longer if the peak load is not applied each time, but yes, a description of how much longer is hard to find.
I wouldn't be sure about building it from parts. I have heard that windscreen…"

"Good find. I briefly read through the documents but will take a proper look tonight.
I have been trying to pin down what actuator is needed, and then based on this what the power requirements would be (to then find the right solar panels and…"

"Sorry for the late reply.
I like the APM power module. I hadn't seen it before.
A water pump should also be self-priming and not mind sucking air. Something like tihs may be OK:https://www.sparkfun.com/products/10455

"Here is a rough sketch-up of the electrics (for the record - never let me wire a house!).
One of the parts I am not certain about is the communication between Pixhawk and RockBlock. A requirement is that there is two-way communication so that…"

"Oh, I forgot to add: Which autopilot system?
I read that the ArduRover/ArduPilot might be too responsive for a long boat as it was intended for smaller RC boats and is not easy to reset.
However, this is a great project and does what we…"

"@David BoulangerGood to keep in mind. It might be different for wing sails but for a long-distance voyage it is certainly better to play on the safe side.
@CezarGood find on the rudder torque calculations.

"I wonder how prone to capsizing either a catamaran or trimaran with a wing would be given that, with a regular sail, I would think (just a guess) that capsizes are due to the helmsman not releasing the sail in time in a gust, or catching on the…"
"Hello Phil,
There are a few examples about. This one is nice because it shows all of the stages and has the software code included.

"Very good effort on your model!
