Performance summary

Generated by AI based on the boat's ORC performance data, compared against all boats on regatta.coach. Since most boats here are regatta-oriented, the comparison can be strict — a "slow" boat here may still be perfectly fast for cruising.

This comfort cruiser offers a balanced sailing experience, with a modest sail area for its size. It reaches 5.1 knots upwind in 10 knots of wind and can achieve 6.2 knots on a reach under the same conditions. The symmetric spinnaker is modest compared to peers, which can limit its performance downwind. The sail plan is well-balanced, with a compact jib relative to the mainsail.

Sailing performance as a polar diagram

A polar diagram shows boat speed at different wind angles and wind speeds. The distance from center represents boat speed in knots, and the angle represents the boats angle to the wind. The wind speed is shown as true wind speed (TWS), not apparent wind speed. Likewise, the wind angle is shown as true wind angle (TWA), not apparent wind angle.

Beat: Sailing upwind (toward the wind)

Beam Reach: Sailing across the wind

Run: Sailing downwind (away from the wind)

VMG Performance

Wind Speed (columns): True wind speed (TWS) in knots - the actual wind speed, not the apparent wind you feel on deck.

VMG (Velocity Made Good) is your effective speed toward your destination, not your actual boat speed.

Beat VMG (top bars): Speed made good when sailing upwind. Higher is better - it means you're reaching the windward mark faster.

Run VMG (bottom bars): Speed made good when sailing downwind. Higher is better - it means you're reaching the leeward mark faster.
