When outfitting your sailboat with a new suit of sails, the question of sail cloth will come up. This video will help you navigate the three most common types of sailcloth so that you can have your sails made from the material that is best for your intended purposes.
Back on the water!
We are sailing and leaving the Mediterranean Sea! We left our slip in Almerimar, Spain, and are heading to Gibraltar where we will stop and wait for weather to safely sail out of the Strait of Gibraltar.
Securing Continuous Furler Pin
The clevis pin on this continuous furler used for a Code 0 sail kept having problems. To reduce snagging, a cotter ring was used to retain the clevis pin. The cotter ring fouled on the furled Genoa and pulled itself straight! Thankfully the pin fell out after the sail was furled and lowered onto the deck. While being put into its locker, the clevis pin fell out and everything landed inside the locker disconnected, but nothing fell overboard!
To prevent this from recurring, we needed to use a different form or retaining pin. Cotter ring failed and a cotter pin would snag on too many things, so our only option left was to stitch together a retaining pin.
Using the available holes, I stitched stainless steel seizing wire through the clevis pin and back through the swivel.
On the other side, I simply sent the wire back to the primary side, until it was all ready to tie off. Once plenty of wraps had occurred, I twisted the wires together and fed them back into the swivel where they remain protected from any snags and safely tucked away.
Most importantly, the wires never tough the top of the torsion rope as the eye splice passes over the clevis pin in the swivel. The clevis pin is fully retained and no chafe occurs internationally. This retaining setup will hold everything in place while preventing any snags on sails or gear up at the masthead.
Furling Vs. Hanks
Sails that are hanked onto the stay are a traditional system that has worked for centuries. The problem with it is the sail never really “goes away”. It’s up or down, nothing in between and when it’s down, it’s all piled up on the deck or boom.
Roller furling is the modern alternative where the sail wraps up around a tube that is positioned either over the stay or inside the spar. The sail can be furled or unfurled part way giving you unlimited variability in the sail size. When you want to put the sail away, it just wraps up and disappears. When you want the sail out, you just release it and never need to hoist the sail up against the force of gravity.
This all sounds very convenient, but what about when something goes wrong? With hank on sails, the sail goes up and down the spar or stay. If the halyard breaks, the sail will fall because of gravity. If the hanks get stuck, they will not slide and the sail will not want to move. Hanks on a stay are almost impossible to get stuck and if they do is because they have lost their shape and need to be replaced. They can be yanked hard to get them to break free and come down, but bronze on steel make for a slippery combination that almost never gets stuck. Hanks on a spar can get stuck, as the sail slides can resist movement on the mast track or get fouled up in the fasteners attaching the mast track to the spar. Different systems exist with differing prices and differing levels of headaches. The cheapest is an external metal mast track where metal slides hook on and secure the sail to the spar. This setup is inexpensive and very secure, but requires maintenance to keep it all moving smoothly. The sail will always go up but might struggle to come down if there is enough wind pressure on the sail. We use this setup on our boat for the storm trysail and it has proven itself reliable.
A more expensive option is a plastic track by Tides Marine where the sail slides are bronze or stainless steel. The setup is very slippery and the sail will always move up and down with ease. In storm force winds (over 45 knots in our experience) we were able to lower the mainsail just by pulling on the downhaul even though the boat was heeled over pretty far and the wind was technically “blowing the sail up” as the wind was blasting it from foot to head!
Some spars come with internal mast tracks where plastic slides fit into the key way on the aft edge of the spar. These work, and are the cheapest of all setups (because it comes with the mast) but it is also notorious for getting stuck on the way up and down. Many people who have this setup will switch to an external track to make life easier and sailing more enjoyable.
Furling systems offer the ease of working everything from the comfort of the cockpit as all the control lines are led aft. This means you can easily steer and work the sails without getting up!
While it might sound convenient, you must also think about “what if” scenarios. More parts means more failure points. It’s not just a halyard and some hanks keeping your sail up and set, you have an entire machine to worry about!
While on a passage with a friend, the mizzen sail got stuck upon deployment. The sail started to come out but then stopped! The skipper had to go on deck and yank the sail out of the slot in the spar where the sail was pinched. The sail was new, so it wasn’t a shape issue, instead it was as simple as the sail not being fueled up tight enough the last time it was put away so the furled sail was pinching on the walls of the spar until it got stuck. The sail would not come out but worse yet, would not go back in! In a storm when you need to reduce sail, having a sail stuck part way is a horrible fate!
On that same sail, the Code 0 sail on its continuous furler gave some serious troubles. The sail simply did not want to fuel in as the winds started to build. Wrestling a Code 0 in winds over 20 knots is an impossible task for 3 able crew as we struggled for some time to get it to yield to our commands!
What happened was the sail had so much pressure that it pressed against the furled Genoa. When we finally got it to start to furl, the Code 0 sucked the Genoa sheets in with it, so we needed to unfurl it and free the sheets; but the wind was stronger and everything was stuck! We eased the halyard to get the luff to pull away from the Genoa, which worked but then the furling line kept falling off of the continuous furler. With the luff tight, it pressed too hard on the Genoa, luff loose it could not furl either. The winds continued to build so we deployed the mainsail and set upon a broad reach to try and blanket the Code 0 to reduce the pressure on it, but this had us sailing straight for a lee shore at 8-9 knots! The Code 0 was so big and effective that the dirty wind from the mainsail was still too much pressure for the furler to operate, so we decided to take it down open like an old time sail. This was a huge mistake!
As we eased the halyard and sheet to bring it onto the deck, the sail became even more powerful as the luff billowed and the sail filled. The power in the sail was tremendous as we rocketed towards shore even faster. We couldn’t turn into the wind because the sail could foul on the rig and make matters even worse so we continued to try with no avail.
The sail began to flog and yank on the yacht as it pulled us towards our destiny with terrible fright! We decided to try again the original way and got the Genoa sheets clear, tightened the halyard, and installed the furling line. This time, the sail furled in with reluctance and we were able to veer off from our course towards land.
It was a frightful experience that thankfully caused no loss to the sail, yacht, or crew. The skipper claimed that if he were alone, he would have needed to release the sail into the sea because it would have been impossible to recover alone on the boat. The Code 0 is of similar shape to our Drifter, but our Drifter is hanked onto a stay, so releasing the halyard brings the sail down without allowing the luff to billow out. The further it comes down, the less power it has. On the Code 0, this proved the opposite, as it came down, it increased in power! Free flying sails are a lot to handle (ask anyone with a spinnaker which sail is easier to bring down: spinnaker or jib) and adding a furler means that when anything fails, the sail becomes a powerful free flying sail!
Sadly, this was not an isolated experience, for the next day in very light wind, we set the Code 0 again, and took it down long before the winds built up like last time. As it furled, the torsion rope got stuck and stopped furling as the electric winch continued to pull on the furling line. When we eased the furling line to fix the furler, the torsion rope spun straight and wrapped both furling lines tightly around it and completely obscuring the furler. Now we had no access to work on the furler! We managed to reach the winch with the continuous loop and put the whole thing on the winch to force the furling line off the torsion rope, then under tension, fix the furler, then continue furling it back in. What if the winds built faster than we could work? What if a squall came up? What if the skipper was alone and didn’t have us or anyone else to help?
While furlers are very convenient, the problems they can bring far outweigh the inconvenience of raising a sail in my opinion.
Sail Balance when Running
The goal with sail balance is to have your sails steer the boat, and the rudder simply help hold the course.
In balanced sails will pull the yacht hard upwind or down, meaning that if the sails are not set to the course, your rudder will have to fight them the whole way there.
When running, it feels pretty tempting to ease the mainsail all the way out. This will present the most sail area to the wind, pushing you downwind, but it also does something unwanted.
The mainsail will become a large area of sail to one side of the boat, and will try to act as a lever arm, pushing the boat to turn in the opposite direction. If the main is on the port side, the boat will try to turn to starboard. If the main is to starboard, the boat will twist to port.
This problem is called weather helm, and usually corrected by easing the main, or reducing its area. Since the main has been eased as much as possible at this point, the only option left is to reduce its area.
As the main comes down, the desire for the yacht to veer upwind will minimize and the downwind pull of the headsail will keep the yacht right on course.
Yes, this yacht could go faster if it were also flying the mainsail, but it would have to work on keeping the helm straight as it traveled. Sometimes, slowing down and reducing sail area will make the entire journey easier and more pleasant.
Next time you are setting your sails, consider which direction you want to go and set the sails that would be most advantageous in reaching that goal, strike any sail that will make your life harder and enjoy your voyage!
