Hi,

I think Rob's designs are great and really revolutionary. However, since my sailing ground includes lots of narrow waterways where effortless and efficient short tacking and short jibing would be huge bonus over shunting I have given a lot of thought to a catamaran that would have the good aspects of harryproas or at least some of them. What do you think of the following? Let's call it HarryCat just to have a name for it.

1) Semi-open bridgedeck design on the principles  of Shuttleworth Eleri http://www.shuttleworthdesign.com/gallery.php?boat=eleri or TEK 35 http://www.shuttleworthdesign.com/gallery.php?boat=tek35 or Grainger Flying Fish http://www.graingerdesigns.net/yachts/flying-fish-11/ with most of the accommodation in the hulls and with only one or two small deck house that you can see over without climbing anywhere. I don't like the weight, windage and looks of those big deck houses.

2) Cost efficient building with panels, preferably with flat panels like KSS or Schionning Arrow series http://www.schionningdesigns.com.au/arrow-series in order to prevent the budget to break the ceiling. Pre-cut flat panels like Schionning Arrow sound like efficient way of building.  

3) Long waterline and not too much accommodation to keep weight and cost in control. Three double/twin cabins would be optimal with head in both hulls and decent sized shower in one hull. Functional galley and comfortable saloon are high on wish list. 

4) Free standing mast on each hull. Benefits of free standing masts are well known to people in this group. Dividing the  sail are ain two smaller sections makes handling easier.

I have also ideas on motoring, down wind kite options etc. but those can be figured later. Please let me know what you think?
