The dual hulls each have nearly plumb stems, vertical transoms, transom-hung rudders controlled by a tiller and retractable centerboards.

[3] Upon introduction the boat immediately became a commercial success and racing fleets were quickly started in North America, Europe and Australia.

The added leverage of the wings for trapezing makes the 17 go upwind like no other catamaran, and the main is easily depowered with a 6:1 downhaul, the mast rotator, 2:1 outhaul and a 7:1 mainsheet.

Downwind, the boat is pitchpole resistant (not “proof”) and a bit underpowered, which makes working the waves a high priority.

In very light air downwind, racers will often stand out on the bow, holding on to the bridle wire to keep the sterns out of the water.
