Headsail

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.

Observation About Headsail Tack Location and Motion Through Seas

We have crossed the Atlantic on a 1968 Morgan 45 with a full keel and cutter rig. This is a CCA style boat with a LOD of 46 feet and a 32 foot waterline. Yes, 14 feet of the boat hover above the water while at rest.

Our bow has a far amount of overhang, with the staysail's tack just behind the beginning of the waterline and the headstay's tack located several feet ahead of the waterline.

One consistent observation we have noted when sailing, particularly when beating, is the way the yacht moves through the seas depending on which headsail is flying. If we have the job lowered and are only flying the staysail, we will ride up and over the waves. This gives us a much drier ride but a significantly bumpier one. Each wave is a wall that must be scaled and climbed down. This greatly adds to the distance we sail as we are now climbing the face and back of each wave, but we do so in a very calm and collected manner. Our speed suffers significantly as each wall almost stops us in our tracks! The end result is a very slow, albeit dry, passage to windward.

The alternative has also been noted. When we fly the jib on our headstay, we no longer ride up and over waves. Instead, we plow right through them. Water pours over the bow as we turn into a submarine and a river of seawater runs down the deck and off the stern. The river can be quite deep, reaching a few inches deep when beating in heavy conditions. This makes deck work less enjoyable and much less safe. Everything is slippery and a few inches of water rushing past can take away your footing, causing you to slip and fall!

On the other hand, our speed drastically improves as we no longer ride over waves, or slow down for them either.

Having a cutter allows us more versatility in Headsail arrangement and sail balance over a sloop, but now I wonder about sloops with their tack location. Most sloops, but not all, have their tack at the tip of the bow; some have them a few feet back. We have the choice of a fast wet ride or a slow dry ride through the seas, a sloop has the setup given to them by the naval architect.

Please let me know in the comments section below about your experiences with tack positions relative to the waterline and how the yacht handles beating into the seas. Also, I would love to hear from those with a bowsprit, does it provide even more drive through the seas?

Easy Headsail Change with Staysail

I would say that the staysail on a cutter is the most useful sail aboard. Not only does it help balance the sailplan, but it also facilitates headsail changes.

If the wind picks up and you need to lower your jib, genoa, or drifter onto the deck, having a staysail set will make your life easier.

Without a staysail, the wind will pull the sail off the deck and into the water. Now you have to wrestle with a wet sail in building winds!

With a staysail present, all you need to do is pull the headsails lazy sheet under the foot of the staysail as you lower the halyard.

The headsail will be pulled up against the staysail and get sucked to the leeward side of it, completely de-powering the sail as it is lowered. As you pull the sail down and under the foot, the sail will come to rest on the deck. Once you have enough of the sail under the staysail's foot, you can drop the rest of the sail with ease and it will fall squarely on the deck and be ready to be tied and bagged.

Headsail Trimming in the Dark

On night watch, you will inevitably have to trim a headsail in total darkness. The moon has either not risen or is new, offering no illumination on the matter at hand. Stars, while bright and beautiful, will not grant you vision of your headsails either.

You could shine a flashlight at the sail, but this will only destroy your night vision making the remainder of the process even harder.

So how do you trim a headsail in the dark? By feel.

If the headsail is too eased, it will flutter and that fluttering can be felt in the sheet as it approaches the winch. Simply ease the sail until you feel it start to flutter, then winch it in until this damaging vibration ceases. At this point, the sail is trimmed in as little as possible so you don't risk being over-trimmed either.

Next time you can't see your sail, simply touch the sheet and let your fingers see for you.
