Sailing the Johnson 18 is fairly easy, because of its wide, stable design. It will plane in under 10 knots of wind, however it will do so much more easily above that threshold.
The asymmetrical spinnaker makes reaching and broad reaching very fast, however heading straight downwind tends to be much slower. This is a normal result of flying an asymmetrical spinnaker without an articulating pole.
The spectacular new Johnson 18
elevates small boat sailing to a new level of perfection. It is
the unprecedented matching of performance, simplicity, and
stability, based on over 100 years of sailing experience on
the part of builder and desigener. This design uses space
age composite materials as they best distribute loads. It is
possibly the first fully computer-optimized small boat
design utilizing a full size prototype. While specifically
designed to be enjoyed by a couple (of any age), the simple
controls make it a boat to work with, rather than against. It
is lightweight, easy to rig, plus easy to trailer. The Johnson
18 is a strict one-design Class ensuring uniformity,
competitiveness, and excellent resale value whether at the
regional, national or international level.
