Heavy Weather Tactics
“Wow, that was a scary! Must have been about a 40 knot gust!”
So what do you do when the winds and seas pick up to extreme conditions?
It happens, it happens to all of us. What we do is the key. The following are a couple of tactics that we employ. I am not saying they are the only ones and I am not saying they are necessarily right. You might disagree. What I am saying is this is what I do. Right or wrong,
whether you agree or not, these are some of the theories that I practice onboard our vessel.
After you have gained some experience, you too will be comfortable when the wind and seas pick up.
“So how do I get that experience?”
It’s really simple; take it all in small steps. Start slow, go on other peoples’ boats. Work your way up to the point that you feel comfortable in heavy conditions. Find out what the boat can handle (I think you will find that in most cases that boat can handle more than the crew can). If you’re a complete beginner, sail only in light air say 10 knots or so. When you are comfortable there, sail in 15, than 20, than 25, etc. Soon you will get the feel for the boat and how much she can handle.
First, try to avoid these situations as much as possible.
Just like we talked about in the “
Lightning” discussion, your tactics should include avoidance if at all possible.
I know there are times when we want to be out there for special events and such, but if it’s not necessary and the conditions are questionable, than sometimes the best decision is to simply stay put securely anchored or in a harbor. Really, you have to ask yourself, “Do we need to be out there?” Often times the answer is no, there is no “Need”. Desire and want, yes. But do we really have to go out? In most occasions, it’s probably not necessary.
You can usually tell when you are going to get hit with a big punch. There will be signs.
Dark sky, cloud cover,
lightning, thunder; you may even be able to detect the high winds as they make their approach on the water. Those with many years of experience will often be able to tell when a gust is coming. How? They can actually see it.
Your VHF radio can also be a big factor in predicting winds and gusts. I know we give these guys a lot of crap, and they deserve it. But sometimes they are right.
So what do we do?
For the sake of our discussion, let’s limit the talk to sloop-rigged boats with Jib and Main only. We will not talk about flying Spinnakers or racing which is a different ball game.
So, you are out sailing, it’s a nice day, the winds are not too strong and you are feeling good. You have all of the sail area up that you can possibly carry and you are sailing nicely along at about 6 knots, than the winds begin to build.
There are two things you should notice with a gradual building of the winds; one is what is referred to as “Weather Helm”, and two is that the boat will begin to heel more.
Weather Helm is the term used to describe the wind
's
effects on the sails and hull that actually pulls the bow of the boat towards the wind.
From Wikipedia…Weather helm is the tendency of sailing vessels to turn towards the source of wind, creating an unbalanced helm that requires pulling the tiller to windward (i.e. 'to weather') in order to counteract the effect.
So the winds have begun to gradually build. The boat is heeling over more and more (this will actually depend on the point of sail you are on. But in most cases will be true, except for possible sailing dead down wind.) and you are
experiencing more and more weather helm; that is to say, you have to turn the rudder away from the wind to keep the boat pointing in the
direction you desire to go.
So now what is happening on our vessel? As the winds build and you are
experiencing more and more weather helm and more heel, two things are going on that are actually Slowing you down.
1) As you are heeled over further and further, more drag is produced by the surface of the hull going through the water.
On some of todays high tech boats, this
effect is minimal or actually the speed increases with heel, but for most of us and on our production boats, what we are doing is actually slowing us down by exposing more wetted surface to the water which in turn causes more drag.
2) To compensate for
Weather Helm our rudder must be hard over to leeward. This is done to keep the boat pointed in the direction we want to go and to keep us from “Rounding Up”. “Rounding Up” is the term we use when talking about excessive weather helm. Excessive to the point that the boat will actually turn into the wind and into irons.....
