Sailing Upwind in Gusts — The Technique That Keeps You Safe

Описание: Join me as I put the Core Sound 17 to the test, sailing upwind in challenging conditions—gusts reaching 20 knots and the tide running strong against me! Watch as I navigate, manage sail trim, and use short tacking to make steady progress. I’ll share tips on balancing the boat, when to reef, and how to stay safe and comfortable in brisk winds.
After the hard work upwind, enjoy the reward: a relaxing, fast downwind run home with the wind and tide at my back. Whether you’re a Core Sound 17 owner, a small boat sailor, or just love adventure on the water, this video is packed with real-world sailing action and practical advice.
Gear Used:
• Core Sound 17 Cat-Ketch
• GoPro Hero (onboard footage)
• Safety Gear (PFD, VHF radio)

How Gusts to 20 Knots Affect Upwind Sailing Strategy
1. Sail Trim and Depowering
In 20-knot gusts, the force on your sails increases exponentially—not just linearly—so the boat can quickly become overpowered if you don’t adjust your sails. Open the leech and easing the mainsheet to spill wind.
Reef early: If sail trim alone doesn’t keep the boat upright and controllable, put in a reef in the main and
mizzen.
2. Active Gust Management
Gusts can be 30–40% stronger than the base wind, and may shift direction suddenly. Anticipate gusts by
watching the water for darker patches and be ready to ease sheets quickly to prevent excessive heel or loss
of control.
Keep the boat as flat as possible—excessive heel reduces upwind performance and increases weather helm.
Use the “ease, hike, trim” method: ease the sheets in gusts, hike out to balance the boat, and trim back in as
the gust passes.
3. Steering and Tactics
In a gust, avoid luffing up too much, as this can stall the sails and slow the boat. Instead, maintain your
course as upright as possible and use the mainsheet to depower through gusts, rather than steering sharply.
Sail on the lifted tack when possible within a gust, as this can provide a speed and pointing advantage.
4. Safety and Comfort
Monitor for increased rig stress, chafe, and shock loading in these conditions. Make sure all crew are
prepared, wearing PFDs, and know how to react to sudden gusts.
If conditions become consistently overwhelming, consider reducing sail further or seeking shelter.
Summary Table: Upwind Strategy in 20-Knot Gusts
Challenge. Strategy
Exponetial wind force Flatten sails, reef early
Sudden gusts Watch for gusts, ease sheets quickly
Excessive heel Keep boat flat, hike out, trim sails actively
Directional shifts Sail on lifted tack in gusts
Rig stress Monitor gear, reduce sail if needed

In short: Upwind sailing in gusts to 20 knots demands early depowering, active sail and weight management, and quick reactions to maintain control and maximize performance
