Re: ALLOY CAT DESIGN
Very nice, a bit out of my budget.
Re: ALLOY CAT DESIGN
Anyone has any ride experience on a displacement catamaran?
Re: ALLOY CAT DESIGN
Yes. Displacement cats can be both the best and worst riding boats you'll ever ride on. In theory and if properly designed / built. They provide a really smooth comfortable ride. However, there are a few potential pit falls....
1. Too much weight in the ends (or insufficient buoyancy) and it will be like driving a rocking horse.
2. Too wide and they become very stiff. A certain deceased Kiwi multihull specialist had a couple of interesting boats towards the end of his career which where to wide. One I know of snapped a helm seat pedestal on its way to the US because of its sharp motion in beam seas.
3. Too high and you can cause either or both of the above issues.
Having read that consider that to make a displacement cat efficient it should:
1. Have fine bows to minimizing wave drag.
2. Be as wide as possible so the hulls don't influence each other adding drag.
3. Have a high wing deck as a displacement boat will cut through waves rather than ride over them and you don't want waves to hit the wingdeck too often.
mmmm does anyone see an issue here?
The moral to the story is you don't want to be the guy a designer experiments on with their first few displacement cats. Go to a proven/experianced designer. Aside from the obvious I'd recommend Roger Hill (http://www.powercatsnz.com).

Re: ALLOY CAT DESIGN
How many hours would you guys guess it would take to do the metal work on this size boat? then while we are on the subject how about a guess on the price for the boat not fitted out??
It sure is a good looking ride but do I want another project ??? LOL

Re: ALLOY CAT DESIGN
Realistically you'd want to budget at least 1000 hrs
