26' Power Cat Project

Being based on Tortola, BVI, I have need of a power boat to get
around the different islands, when I'm not using the trawler on which
I live, both for my business, a sail loft, and for personal
pleasure.  For the last nine years I have been using a 23' Seacraft,
center console, with a 200 Yamaha; great riding boat for a monohull,
but the milage isn't great and with gas now at around $4.00 a gallon,
a might expensive to run.

A small boat builder in St. Thomas, Morgan Avery, has a Prindle 19
sailing cat that he decked over, bolted a couple of legless plastic
lawn chairs to, hung a 12 hp outboard, and takes it almost
everywhere, including St. Maarten, almost regardless of the weather.
It goes about 25 knots on about 1 gallon an hour.

One of my sidelines is managing racing sailboats and I happened to be
sitting on one of my projects with the engineer / boat designer I
use, OH Rodgers from Tampa, when Morgan cruised by in about a four
foot chop.  I mentioned to Oh that I would like something simple like
that, but a bit bigger, capable of carrying six people.  What he came
back with is: http://www.doylecaribbean.com/rodgers26/index.html

I am having a set of hulls built in Trinidad by Jeffrey Chen at CISL
Marine.  Jeffrey is just finishing up a 75' power cat, having built a
62' previously.  While the drawings show molded fiberglass cross
beams with integral storage, which they will be when the boat goes
into production, my boat will have aluminum mast section beams.
Building the first one as a one off will allow us to make any changes
we think are needed, such as adding splash rails or changing the
buoyancy.

I will use twin 50 hp Tohatsu TLDI outboards as they have a pretty
good ratio of power to weight and fuel economy.  Four strokes may be
slightly more fuel efficient, but the extra weight and cost are
considerable.

The expectation is for 25 knots with six people in one meter waves
getting four miles to the gallon, five mpg with two people at 25
knots.  There is almost 36" of clearance on centerline between the
hulls so unlikely to be slapping waves in normal conditions.  1"
aluminum pipe rails for security and lightness, with the same used
for the combination top and windshield frame.  Clear vinyl side
panels will enclose the helm and seating area making the boat usable
in practically any weather.

Simple, economical, no frills, and inexpensive relative to what else
is available on the market.
