Strategies and techniques for solo heavy weather sailing

Sounds like you reacted appropriatly and then performed the requisite postmortum analysis.

To contribute to the question you asked... Here is a personal story. A strategy I learned the hard way and "on-the-fly" was to keep the sail plan balanced. This keeps the boat moving forward with sufficient power to punch through the waves.

I remember a time when I was sailing a 22' boat across the Albemarle sound. My son and I were on a week-long cruise. The wind was stiff so we left our anchorage under jib alone. It was a hanked on jib. As we left the anchorage we encountered very square, closely spaced waves that were sometimes breaking. It was a long fetch over rather shallow water and we were getting hammered by short & steep waves... making very poor time. This boat had a rolling boom so I could "reef" the main as I saw fit. I switched out my headsail for my "storm jib", rolled out about 1/3 of the headsail and we started moving forward and slicing THROUGH the waves instead of bashing over them. We played with the balance of the reef on the main until the boat was moving forward at hull speed. We were definitly getting wet as we sliced through the waves but we were no longer getting bashed. My son was about 9 at the time.... he loved the spray coming over the bow and insisted on holding the tiller most of the day.

Later in the day we overtook another boat sailiing under headsail only and I could see from a distance how most of that boats motion was up and down instead of forward. Seeing that after what we just experienced really cemented in my mind the importance of getting balance between your sails. Reefing is definitly part of the equation in heavy air but it is only PART of the equation.

I went out yesterday for a quick sail in what was supposed to be 2' swells. It turned out to be 3-6' with 15-25kts of wind. While the boat and myself handled it OK, my tack was anything but graceful. I was flying a reefed furling genoa. During my tack the force of the wind got the best of me. The line slid through my hand a bit before pulling my hand toward the winch. During this my finger was knicked by the edge of the winch. Lesson learned - gloves should have been worn and I should probably have gotten more wraps on the winch earlier.

What I'm really interested in, is hearing what techniques you guys use when the wind and waves pick up?

It sounds like you were using a pilot with autotack function? Good. If not, get one.

Timing is everything. Practice this in blocks. The jib needs to come across as the wind crosses the bow so that you can get it sheeted in JUST as it can fill (hold back just enough so the wind helps pop it through, but only just enough). Minimal grinding. After hauling hand over hand with a single turn on the winch (more turns is asking for overrides when hauling fast), the MOMENT the load increases throw on a second or third turn and have the handle at the ready (but not in before adding the turns because that would make adding turns awkward). You have to be able to throw the turns on quickly, easily, and safely (keep the fingers well away). The trick is adding the turns at the right time and keeping tension on the tail while doing this. Then it is smooth. There should be a good handle-stash spot within easy reach of winch.

Easing the main a little just as the bow passes the wind can help the boat accelerate and not go into irons. One less thing to worry about or mess up. If you can pull the traveler above the centerline at the start of the tack that is a good alternative, and also helps speed the turn with less rudder.

Also a good point about reefing. It's easy to roll up a little jib, but this can lead to imbalance. Unless the overpowering is very slight or only for a few miles, reefing the main and jib in concert will usually give better balance, and give the option of rolling the jib further. I would have reefed the main coming out of the marina, and then based on how it felt, let out some jib. You can always let out more jib.

I'm not sure I can really answer your question. I have found it's rather boat specific. Thinwater just just answered with some good guidelines. One thing I will add is, I think as everything is moving faster, wind, waves, the environment, we tend to feel we need to move faster. I feel the opposite is needed. Slow yourself down. Look at where the waves are coming from and how they will affect your tack. Make sure you have all lines ready and everything is set before you start the maneuver. Keep things under control. Think through each step you are going to need to do before you start the tack. Then execute.

When I am in sporty conditions, like you I often fly a reefed headsail only.

I have found that an extra wrap or 2 on the sheets helps a lot…on the working sheet, it allows me to get the line out of the self-tailing jaws without having the line pull my hand back towards the winch. The stronger the wind, the more wraps on the winch I like to use.
Similarly, before my tack, I put a few wraps of the lazy sheet on the winch…so when I start my tack, I can quickly pull the sheet tight and the. Let the wraps hold it so I can get the line in the self-tailing jaws without having g to use brute force to hold the line (and risk having the force pull the line through my hands. Again, the stronger the wind, the more wraps I use. Also, I like to try and get the sheet Pulled in pretty tight before the wind totally catches the sail. That reduces the amount of winching I have to do on the new tack (and prevents flogging).

Finally, I experimented with jibbing the other day in windy conditions, flying just my jib and I was staying close to the arena, so lots of tacking. The jibe was actually way smoother than a tack, and I think easier to control. Practice the jibe the ne t time you are out (without the main up) and see if works for you. In strong winds, I won’t jibe if I have the main up (unless absolutely necessary). But with just the Genoa up, particularly reefed in strong winds, a jibe may be the answer.

In heavier air I run 2 turns on the lazy sheet and 4 on the working sheet. With the 2 turns I’m able to pull the new sheet in quickly and have not had any overrides. With 3 turns I have had overrides in some conditions. After I get the slack out I add the extra two turns, and that’s enough to prevent any slipping with minimal tension on the tail. In most conditions 3 turns is enough to prevent slip, but above 20 knots 4 seems to work better. When releasing the old sheet I just pull upward on the tail. That lets all the wraps off without needing to bring my hands close to the danger zone around the winch.

I am not familiar with your specific autopilot but I'd be surprised if it doesn't have an auto tack function.

I have a Raymarine P70 control head and I believe an ACU-100. I'm not sure if it has an autotack function. I took a quick look on Raymarine's website and only saw installation manuals. If it doesn't, could such a feature be added by using a tablet as a controller? Seems like a pretty easy feature for a developer to code

If you have -1 and -10 degree buttons (port), and +1 and +10 degree buttons (STB), try pressing the 2 port or starboard buttons at the same time. On my Raymarine St6000, that starts the auto tack. So to tack to port, press -1 and -10 buttons at the same time and release.

If you get over wrap when pulling in a sheet on a winch, your lead to the winch is not correct. If you notice many winches are set on their base with a wedge. The fairlead from the sheet's block to the winch is just as important as the fairlead from the clew to that block on the rail or inboard on a track. Adding a second block after the first one could solve the override problem. Using a slightly heavier line, could make the line more comfortable to handle, as a side benefit.

Hello,

As mentioned by DLJ, when wind and conditions speed up, you need to slow down. Think more and move less.

Think each maneuver through before you start. Plan your next move carefully and completely. Execute the plan then think about any adjustments you need to make the next time you do the maneuver.

For example. you're beating your way upwind in 'sporty' conditions. You will need to tack in the next few minutes. Prepare by ensuring the lazy sheet is run properly, pull the slack out of the sheet and put 2-3 wraps on the winch. Center your traveler or even lower it a little. Check the tail of the loaded sheet. Will it run freely when you cast the line off? I like to run the tail to make sure there are no kinks. Look ahead before you tack. Are there any hazards around that you need to be aware of? When you're on the new tack will you be clear of other boats? What waves are approaching? Time your tack so you won't be crossing a large wave. TACK SLOWLY. As soon as the boat is head to wind release the working sheet and pull the lazy sheet. The goal is to get the sail pulled in as much as possible before the sail fills and gets loaded. Then put the sail in the self tailor. When on your new course trim the headsail and then make any fine adjustments on the traveler. Review the last maneuver. What worked well? What could be improved upon?

Steering upwind in big seas is challenging and takes a lot of skill. You need to actively steer around the waves instead of just holding your course and bashing into the waves. Sometimes you need to sail a little lower than normally so the boat is powered up has speed to get through the waves.

And good for you for going out is challenging conditions and practicing.

^^ This is the number one rule for singlehanders. Plan it through and get it right the first time.

Re. adding and removing turns.

Before starting the tack I remove the working sheet from the tailer (handle out). It should NOT be highly loaded or you did not put enough turns on it. The tailer should never be holding more than you can hand tail easily with one hand. Then I remove one turn without letting the line slip. This will require a firm grip, but often it makes the release smoother (with full turns you will have to fool with removing turns during the tack, which is awkward).
As the sheet is released, do NOT let it fly in strong winds. It will tangle. You can let go once you get some tension on the new working sheet.
Add the turns to the working winch before you put the handle in. Yes, you will probably have to add one more turn after grinding some. I generally hand tail for the first bit so that I can more easily add another turn. But if your timing is good, there should be very little grinding; the sheet should come in just as the sail can first fill.

Tip. If the winches are so far apart that you can't reach them both without running around, after step one, put the sheet back in the self tailer, but wrap the sheet around the wrong side of the winch so that when you pull from your position at the leeward winch it winds right out of the tailer. But still hold on to the tail.

Lots of practice, perfecting one step at a time, while thinking about how they all fit together. Perhaps the main thing to watch is the rate of turn, so that every step is timed to match the slow change in wind direction.
