My Caledonia Yawl was finished enough to have her on display in the Maine Boatbuilders Show in Portland in March, but it'll be several more weeks before she sees the water. She is a small cruising sharpie with a single lugsail which is reefed by rolling the boom. Because of this her displacement is 900lbs. Leeway is counteracted by the use of 'chine runners'. She does not have a centreboard or leeboards, although at one time she sported the latter, which did not appreciably improve her windward performance.
Alternative propulsion is by oars which are permanently shipped through ports near the gunwales.
The photo was copied from the Web site of Dave Bolduc . We trailered her up to Door County, Wisconsin, about 250 miles north, last summer. The photo was taken on Lake Opeka, a small lake in our town. Chicago's O'Hare International airport is just out of the picture to the right. We cruise in 'Jabiru' regularly in the warmer months for periods of up to a week and have covered 985 nms since we got her in 1994.
