This new list, and our new-to-us powercat, have come along at about the same time. We are in Victoria, B.C. We have just moved from a Nonsuch 36 sailboat. The Zeta 42 is one of about 20 powercats built by Zeta, a Richmond, British Columbia based manufacturer. Zeta primarily builds fast cruising mono-hulls of various sizes. Each of the cats is a bit different. They are all custom and to a degree they are all a bit experimental. Ours is an early one - from 1994. It has asymmetrical planing hulls, with steep deadrise and substantial planing strakes. All the cats are powered with large engines (some gas; most diesel). We didn't go looking for a catamaran. We were confined by the length of our berth. We found that this boat offered good accommodation; excellent light and liveability below; and good performance. The engines (gas, 8.2 litres each) however are tired. They do not live an easy life, constantly pushing this load at speed. I am only beginning to learn that non-displacement power boats (including cats) are all about engines. There are some difficult (and expensive) choices to make. We are going to see how we use the boat this season. It may be that a constant 20 kts is not particularly necessary or relaxing. It may make for a better combination to put in a pair of smaller diesels and proceed much more sedately. One question: all boats I know eventually suffer from glazing leaks. But this one (which is generally very well built) shows signs of heroic efforts being made to seal the large house windows. Do cats, with their large open spaces and two hulls, simply work more than conventional vessels, such that this leaking is more prevalent? What's the solution? Possibly older-style, more flexible, caulking materials? Any suggestions?
