I'm envisioning a fully seaworthy boat, a full set of safety equipment and 90 days of provisions. The rowing equivalents are here:...
Cute, but not practical for me I don't think - I feel an approach with the interior on a gimble would add too much weight and cost. I've toyed...
This may be stupid question: At this kind of power and speed, is there any chance a paddle wheel would be more efficient?
You mean a single-bladed propeller? I've seen it implied that less blades are most efficient for lower-power and speed situations - which is...
Thanks; this backs up what other resources seemed to be saying but it's nice to be sure. What pre-existing solutions are there to make a small...
For a low power (e.g. human-powered) boat, are there any potential advantages of running two separate propellers instead of one from the pedals?...
Some small human-powered multi-hulls I had a reply from the Hallin Marine rowing skipper: "The boat was very wide with the amas [supports]...
Anyone know how the Hallin Marine rowing tri was designed to deal with capsizes? (and whether it had any?)....
0.5 bhp is generous, sustained is more like 0.25 bhp. It's generally essential to plan a route with the currents. Nevertheless, pedal boat Moksha...
Thanks; I understand thinner is better. I'd want to be able to sleep within the cabin of the main hull, so shoulder width plus wriggle room will...
I'm envisaging an sea-/ocean-crossing pedal-powered boat. Pretty much all of the solo versions of these boats to date have been monohulls, and...
Further research might get me to rethink/abandon this design. According to http://www.bluefish.org/jettuna.htm, around 80% of the thrust of the...
Thank you; I've been reading a lot about RoboTuna already :)
There's a lot to be said to having hands-free for other tasks. My current design would use hands and feet, BUT the hand controls could be...
Thanks; I've browsed quite a few pages of that thread but it sounds like it's worth my time going through the whole thing. Interesting; I...
I've seen a few designs for boats that are finned or sculled from the rear, but none seem to resemble how many fish power themselves. Fish seem*...
As a point of comparison, have you seen the Junk Raft project? http://junkraft.blogspot.co.uk/ When they first set off sailing from the USA...
