Taming the Roll: 

Using a Mizzen Sail as a Riding Sail on a Ketch

Anchoring your yacht in a rolly anchorage can be an ordeal for any sailor, however as Ketch owners we can tame the beast just a little. The constant rocking can disrupt sleep, make cooking a challenge, and even test the limits of your sea legs. But, there's a simple and effective solution: using your mizzen sail as a riding sail.

Before we dig into the how-to, let's understand the "why." When anchored, your ketch lacks the forward momentum that normally keeps it tracking straight into the wind. The wind pushes and pulls at the boat, causing it to yaw back and forth, and with each swing, the hull swings side onto the swell and starts the vessel rolling. A riding sail deployed strategically helps counteract this yawing motion, keeps the bow and the vessel pointing into the wind and helps in reducing roll,  creating a more peaceful anchoring experience.

Preparing Your Mizzen Sail as a Riding Sail:

• Reduce Sail Area: Reef your mizzen sail or use a smaller riding sail. Too much sail area can create additional problems.

• Sheeting: Sheet the sail and secure it firmly. Don't sheet it flat; aim for a slight angle to prevent excessive flogging.

• Fine-tuning: Adjust the sheet tension and sail angle based on wind strength and rolling behavior. Experiment until you find the sweet spot that minimizes roll without creating excessive heeling.

Additional Tips:

• Practice makes perfect: Get comfortable deploying and adjusting your riding sail in calm conditions before venturing into anchorages with more challenging winds.

• Monitor conditions: Be mindful of changing wind strength and direction, and adjust your riding sail accordingly.

• Safety first: lower the riding sail when leaving your vessel unless wind strength remains constant.

• Respect other boats: Position your vessel so your riding sail doesn't cause your vessel to interfere with other anchored vessels. You will pointing into the wind as they swing around the anchor.

• Remember: Using a mizzen sail as a riding sail is a temporary solution as swell comes into your anchorage, not a substitute for a better anchorage or anchoring techniques. Always consider finding a better anchorage. 

I once spent several days in Wineglass bay, on the East Coast of Tasmania, I was hiding from a storm, the best anchoring positions were taken by local fishermen also hiding from the storm, the swell coming into the bay was constant and the rolling motion on TinTin was nothing short of punishing, that was until I put up my mizzen. My crew almost hugged me, then asked why I had not done this sooner, I just forgot about the technique.

I tried the same technique when I anchored TinTin in the Yasawa's, Fiji, the swell coming into the bay was so bad, that nothing worked to stop the rolling or to improve the situation onboard. At times I was thrown from one side of the cabin to the other, after two days of this punishment I said goodbye to the chance of swimming with Manta's.  I up anchor and left.  It was such a relief.

Benefits of Using a Riding Sail:

• Reduced roll: Enjoy a more comfortable and restful anchoring experience.

• Improved safety: Less rolling means less stress on your boat and equipment.

• Simplified boat handling: A stable boat is easier to handle when raising or lowering the dinghy and climbing on board.

• Cost-effective: Utilizing existing sails eliminates the need for additional equipment.

Limitations to Consider:

• Complexity: Setting up and adjusting a riding sail requires some practice and know-how, but not a lot.

• Weather limitations: Not suitable for strong winds or rough seas. In stronger winds you need to reduce sail further.

• Potential wear and tear: Frequent use can increase wear on your mizzen sail.

• By harnessing the power of your mizzen sail, you can transform a rolly anchorage into a bearable and safe location.
