Welcome to the website of McGowan Marine Design, Inc., featuring the
design work of Laurie McGowan. Opened in 2001, this is a full-service boat
design office providing custom and semi-custom design work, concept drawings,
CAD, stability, speed, sail and rigging analyses. I've started doing Trim and
Stability booklets for passenger carrying tour boats, and also do line and
construction drawings for US tonnage measurements of Canadian-built fishing
boats.
Featured Design - Czarina a 27' Solar/Electric
Ketch
Czarina was
commissioned by repeat Covey Island Boatbuilders customer, Tom Goodwin, of
The Bahamas. Tom, an experienced sailor, seaplane pilot, and artist, was very
clear about the detailing of his boat. Starting with his sketches, and based on
a hard-chine schooner by Edward A. Stinson of 1890, we were able to model a
husky yet sleek design. It's hard to tell if the ketch is 22 or 40 feet long at
times.

Czarina is powerful with lots of sail. Apart from the
all ‘glass centreboard and trunk, construction was completed using Covey
Island’s tried and true wood/epoxy methods. Strip planking below the
chine, with mahogany plywood above has resulted in a very strong vessel, and
the crew at Covey Island's attention to detail is dazzling.

The
“Thoosa” electric drive setup by
NGC
Marine Products in Milwaukee, Wisconsin, was chosen because an
outboard in a well would have ruined the stern (and would have been awful to
use), and there was no room nor desire for a hot, loud, and stinky diesel in
the tropics. Ample sunlight and an incredible electric motor tipped the scales
in favour of a renewable energy system. Just under hullspeed is reached at
half-throttle, and the boat can cruise like this for approximately 5 hours. And
the motor is silent! Flexible solar panels are laid out in the cockpit for
battery recharging when Czarina is moored, or 'regeneration' can take
place by allowing the prop to freewheel while sailing.
