Sailing In Heavy Seas

Posted on: June 17, 2011

There are all aspects to Heavy Weather Sailing and we'll touch on a few. It is different for everybody, not only because of our personalities, but the capabilities of us and the boat. When we think of Heavy Seas, we conjure up Storm conditions, pouring rain, Breaking seas, and more. Some of that is a reality, some not. So let's get it in some sort of perspective.

First, you don't just leave without checking the weather. Some still do…Why? They have their two weeks off and nothing stops them, even common sense. They might think they can out run the weather…In a Sailboat? Are you kidding me? They might feel it will veer off or take longer to get to them. I know you only have a certain window of opportunity to get away, and that is when disaster strikes…It is in the papers & internet with the Coast Guard there. They seem to save us from ourselves, time after time. That's one Organization I must tip my hat to.

Being prudent is key. Check the Weather how it is now…Seas, wind, etc. Know when the last weather front came thru and when the next will come. Here's a general scenario…it's Monday and they call for rain tomorrow, Tuesday…that would mean (generally) that a Low pressure system is approaching bringing rain. They say it will stop raining Wednesday afternoon with clearing over night. That would mean the Low will pass with the rain and (generally) bring in a High pressure system. A high usually comes in with gusty winds and settles down giving those nice Blue skys…this will last till the next system approaches…During the Spring and Fall seasons the systems can come day after day.

If it is during the summer, I would wait for the low to pass, and leave Wednesday afternoon as long as the predictions say the High would hang around for awhile and the next system approaching would be Saturday or so…but this is me.. take the nice weather to your next Harbor. Some of my Harbors are hundreds of miles away. Not all weather systems work like this, but you ole' Salts know the rhythm of the systems..and an eye to caution.

Second, with that aside, how do you get in Heavy Weather? Sometimes you're on an extended Sail and a fast approaching weather system comes in or one that formed quickly out of nowhere veers your way. I can't tell you how many times that happened to me. But being Offshore not Coastal helps out a great deal. It can blow up to 40kts and (generally) the seas are large and high, but not breaking…Coastal would be a different story, and being in the Gulf Stream is another. In later episodes, we will talk about these variables.

Earlier we talked about getting things in perspective…. When Sailing Offshore, it does not turn instantly wild…Even if someone turned a switch to make 30 or 35 knt winds blow all of a sudden, the seas would slowly start rising. Of course you would shorten your sails….. if you knew a blow was coming, you would have shorten your sails already. But as mentioned, seas build slowly taking days, but sometimes just hours depending on the how fast the winds build. Wind is what lifts the sea up in waves. So this period of time as the wind builds, and seas build, gives you time to adjust your Sailing. You shorten your sails or you may opt to put up your storm sails, below you would close the hatches, windows, put loose equipment and accessories away so nothing flies around. Then on Deck….anything not needed gets stowed, anything that can get airborne is also stowed or tied down. Foul Weather clothes are donned and some soup/nourishment consumed to keep up strength.

Third, now that you are set-up for Heavy Weather, you realize there was time to get things done. As the seas build you will find they get high, and on top of that rise is a long flattish area, then you go down again. This is Offshore, closer in-shore they get steep and short causing other problems, which we will get to in another Article. But being Offshore (generally) the seas get High and long giving your sailing experience some exercise. If the Sails are shortened enough, your heeling is at a minimum, and your sea motion is OK….see…your working into the building conditions. In 30knt winds you can still be on a close reach, taking the seas head on…well almost…As the wind and seas build even more, you will find the tops of the seas that were once long & flat are getting shorter in length. I've stayed in a close reach in a steady 38knts with gusts 42-45. Again, if you don't have out too much sail, you won't be wildly heeling over and hanging on…the right sails out bring the right motion. If the wind builds higher, this is where things change, your destination becomes second to anything else….once you realize this and don't fight to get to your destination, you got it beat.

You have to remember this storm is not going to last forever.. it will blow itself out, and this front will move on. So when I said destination becomes second, then what is first? Your boats sailing characteristics. I have found thru the years that all Sailboats have their own best point of sail. Meaning the point of sail where the sailboat itself feels comfortable. Some sailboats can head into those seas better than others, falling off and running is fine also, because you have a wider angle to work with. You want to have enough sail out so when the seas come up behind you, it doesn't swallow your stern. Sometimes idling your engine in forward gear gives you enough momentum to slide in front of the seas, because the seas itself are blocking the wind and leaves you…well dangling in a sort of doldrums till some wind fills your sails…by that time, your stern may be under some water…I've been there, learnt that lesson quick, seeing the seas engulf my stern….So now you just find the sweet spot of the boats' characteristics to the seas at hand. The only way right now I can describe this, is the fluid movement of Jujitsu…how each time they make a move, it just flows…well the wind and Heavy Seas are generally constant hour after hour…waves coming in the same direction along with the wind, now put in the your Sailboat there moving along at the right speed, not heeling wildly even in gusts, using it's best point of sail, engine idling in forward gear, whether it is into the seas or away…it's like a heart beat, you'll find the pulse of the wind and seas and ride it thru. Better days are coming, maybe later on, or tomorrow… that we know for sure.
