I'm still with you, on cutting down the oak tree, Steve, But at 6600
pounds of wheel weights, I draw the line! ;-)

It's called an AS39, perhaps. Clyde

It may be worth keeping in mind that,of all the things that make
the MICRO"so good a boat"it is it's diminutive size that usually wins
peoples hearts if not their wallets.At least that is how this smitten
owner/builder of a MICRO feels.

I don't know about the cube square law but,
the cost, weight and time to build a boat increase
proportionaly to the lenght cubed. So a 16 footer costs
8 times as much as a 8 footer.
This only applies when you buy or build a boat. When
you sell the boat the price is proprotional to the length:)

Scaling a boat is non-trivial, cube square law and all that.

As soon as the weather breaks, I'll get out my az and draw knife out and

Now all we have to figure is where to round up 1125 pounds of wheel

I'm wondering if the "Micro" is so good a boat, would one 2.5 times
longer/wider be also goo? 36 ft. long and 15 ft wide. Lots of room inside
for a live aboard!
I suspect the motion inside would be rolly.
Any thoughts?
