Wind & Sail Direction

Catamaran — Wind Direction & Sail Trim

Catamarans are wide and stable, allowing sail angles slightly wider than monohulls. Use the points of sail below to set your trim.

Wind 90° off bow · Sail 45° off centerline

Sail Angle

Eased ~45°

Close Hauled

Wind: 30°–45°

Sailing as close to the wind as possible. Sails trimmed in nearly centerline.

Sail Angle

Pulled in tight

Close Reach

Wind: 45°–60°

Slightly off the wind. Ease sails a bit from close-hauled position.

Sail Angle

Trimmed 25°–35°

Beam Reach

Wind: 90°

Wind directly from the side. Sails eased halfway out — fastest point of sail.

Sail Angle

Eased ~45°

Broad Reach

Wind: 135°–150°

Wind behind at an angle. Let the sails out further.

Sail Angle

Eased 60°–75°

Dead Run

Wind: 180°

Wind directly behind. Sails all the way out wing-on-wing or goosewinged.

Sail Angle

Fully out ~90°

When to Reef

If you think you must reef, then it may be too late already.

Reef early — before conditions force your hand. A well-timed reef keeps the boat balanced, fast, and safe.

Catamarans don't heel to depower — reef earlier and more aggressively than a monohull to keep the windward hull planted and avoid burying the lee bow.

Reef Stage	Apparent Wind	Sail Reduction
Full Sail	0–11 kn	0%
1st Reef	12–15 kn	~25%
2nd Reef	18–20 kn	~40%
3rd Reef / Furl	22+ kn	~60%

These are general guidelines based on apparent wind speed. Actual reefing thresholds vary with sail area, displacement, sea state, point of sail, and crew experience. Always consult your vessel's own reefing chart or manufacturer specifications.
