Micro liveabord cruiser

With just one bar through the middle, and two peddles there is enough room to sleep under it when the two peddles are both level with the ground.

Is it possible to have a gear system that is super simple, still leaving room for sleeping full length

 

Jeez those things are ugly. lol.

An empty wheelbarrow is easy to move around. One full of water, food, extra clothes, etc. while you and your wheelbarrow are knee deep in muck is not.

With that much constrained space, I think pedal wheel drive probably has to be sacrificed. Its just not particularly practical other than for showing off at a marina. Law enforcement might tell you its not street legal for you to drive your boat on public roads etc. and you would quickly tire pedaling it around.

What you might do is rig your boat as a trailer and have one of those folding bicycles with a hitch attachment. The bike lives on the outside of the boat somewhere while sailing, and once ashore, you can both port your boat around AND you have a practical way of riding around without having to lug the whole thing with you all the time.

 

Just a vague observation, these boxy designs are amazingly space efficient.
Why is there a deck around the "dog box" ? Surely a sloping side would more more roomy inside and more aerodynamic.

The sharp edges at the bow and stern are so performance sapping. From an interior room and aerodynamic perspective, curved, sloping decks are a much better idea without restricting operator access to the sail.

There is so much that could be designed better.

 

Probably as walk around deck and a place to lash things down (mast etc.).

But much harder to fabricate. These things are mostly 90 degree joints and built like a piece of furniture. I don't think performance was much of a design consideration here.

Agreed, Layden's Enigma or Paradox are much more... elegant solutions.

 

Walk around on a 8 x 4 square ?? C'mon.
Mast storage is just as unrealistic. 4 foot overhangs on each end. A crutch groove on the cabin top would be more useful when towing, as it would be centered for turning on a trailer.

How hard is it to bend a curve in 1/8 inch sheet of fibreglass, and then back it with more glass ?

Performance on a sailboat is always an issue. Especially with such bad sails.

 

Did you look at the pictures?

 

A couple of similar designs are the Ocean Explorer or for a larger version the Ooze Goose. Ocean Explorer https://www.duckworksbbs.com/product-p/pk-oceanexplorer.htm OozeGoose https://www.duckworksbbs.com/product-p/pk-oozegoose.htm

 

If you mean like this one, it's nothing that a couple of fabric loops on the side of the sloping cabin wouldn't handle. Side deck mast storage on a trailer is problematic, as it interferes with turning.

I am aiming at improving interior room, ingress and egress, as well as windage. I would even think about a slightly wider cabin to make paddling easier.

 

I'm inclined to agree with you. But the designer/builder probably found the utility of being able to walk around the cabin top better than having a couple more cubic ft. of interior space.

 

Everything is a pay off. There are advantages and disadvantages to everything.

I would love to see your better designs, but they will all have some good and bad points.

This little puddle duck cruiser is exactly what I want. I know it got limitations but it's easy to build and have some fun on the water with.

I'm just trying to figure out a way to make her amphibious and able to be peddled.

There must be a way, where there is a will there is a way.....

 

I am just adding this French Amphibious Beach Catamaran because not only has it solved the rudder steering problem, but also the skeg/leeway problem.
It might inspire a few ideas. Cata Kite, or Sea Quad is a French design

Looks fun, but that cat is not able to sleep in or go for short cruise

 

Pay attention to the shape of the hull and the wheel/rudders.

 

This one can inspired you, the launching is expected next spring and an Atlantic crossing towards Guadeloupe is planned (same route as "Route du Rhum"). It is a Micro10, by architect Paul Fisher : Length 10' , expected average speed 3 Knots.
