|If you want to sail in
weather like this you would be happy to be in a Core Sound 20. This boat
was fitted with a cuddy cabin. Dawn Patrol was launched for the first
time at the 2008 Everglades Challenge and came through unscathed
finishing fourth. She has since won her class in the EC
Shown in this picture is our method of "butterfly" construction: the sides are fiberglass/epoxy taped to the bottom panels just at the bow. When the bottom panels are wired together along the keel centerline, and opened like a book, you have the sides in position and ready to wire. The hull panels are pre-engineered, so that there is no lofting, no jig or strong back required.
Our "butterfly" construction technique allows easy hull assembly. Shown at right, the builder assembled this hull single handed.
At the point at which this picture was taken: the butterfly is being folded into the hull shape. The centerline has been wired and opened up and the bow has been wired.
|After the installation of the temporary
bulkhead and transom, the sides are wired to the bottom.
This boat is almost completely "stitched" and
will shortly be ready for "gluing" ie.
fiberglass/epoxy taping the seams.
Note that the pre-attached stringer, which appears to be drooping at the bow above, align nicely when the hull is wired/folded into shape. This is the stringer which will carry the seating.
|Also clearly shown are the cutouts in the temporary bulkhead to take the keel batten and spaces for the chine taping to run through.|
|The Core Sound 20 design was
originally commissioned as a daysailer and camper sailer which could
win races, specifically...a boat which could beat the
Core Sound 17 which had been gobbling up all the
trophies. The boat has lived up her promise. Not long
after she was officially launched in the summer of '99,
she won the grueling 2 day open water Independence Day
Race. For more information: The
In spite of her energetic sailing characteristics, she is easily handled; even with our 2 1/2 year old grandson on the helm.
The photo (above) was taken by the committee boat, which clocked her speed at 8 knots, with bursts to about 10 knots.
Notice the rig: On this boat, all of the controls are lead aft to the helmsman, allowing the boat to be reefed and unreefed without leaving the helm. With increasing wind, we were able to lower the sails in order to lower the center of effort to reduce heeling.
|the sails (see top of masts) and reduce the heeling force allowing us to sail safely and powerfully in 20 -25 knots|
|The CS20 above, sailing in Australia, shows the mainsail furled and the mizzen is stepped in the third mast position, giving the boat perfect control during the squall. The sun is back out as the worst of the squall has passed and it can be seen by the wake that she is still making good speed.|
If you are not familiar with this rig, we suggest you go to Why a Cat Ketch?
