A kayak stability question

Thanks, you guys. Sounds like exactly what I needed to know. Looking forward to getting this thing tuned in!

I should mention that following other discussions here I should not recommend or in any way endorse rec. style kayaks due to their flotation issues when swamped. Just wanted to mention that.

Perhaps not, but they’re about as stable as any boat can be. Used near shore in warm water for short distances they can still be a lot of fun. The problem with rec (wreck) boats is that people try to use them way beyond their “designed” purpose.

We have two rec kayaks so the kids can have fun with us. Very stable and it’s easy to swim from them. Fishing us simple too. They are fat and slow, tracking like a basketball but we knew that before getting them. Nothing could be farther from my elite surfski.

For a complete newbie figuring out what is this “designed” purpose can be a problem.

A good observation. This is completely the fault of the mass-production recreational kayak industry. Well, some of it is the naivety of people… but let’s just gloss that one over, shall we? :wink:

@SpaceSputnik I just did a quick google on “recreational versus touring kayaks”. I didn’t find the site I most wanted, looks like it no longer exists. But I did find a few that talked about suitable use for each type, like this -

I completely agree it could be better, like talk about the reason for features such as perimeter lines. But trust me, you will figure that out in the first half hour of that rescue class. Also the reasons some prefer skegs over rudders. :slight_smile:

thanks Celia

Okay, so I took the boat out and ran through nickcrowhurst’s well-written instructions. And apparently I’m a moron. I had a nice little headwind at times, so I felt pretty good about the test conditions. I’d started with the seat in the middle of the fore/aft travel, and the boat seemed to have a hard time tracking straight, so I kept moving the seat forward. And forward. And forward. It’s almost as far forward as it can go now. Each time I also adjusted the foot braces to get my legs back where they need to be. With the first adjustment, the directional stability seemed to get better, somewhat. That’s why I kept going. But honestly, once I got to where it is now and just paddled around for awhile, I couldn’t keep that boat going in a straight line to save my life.

I checked myself constantly to see if I was leaning the boat to one side or the other, and although this boat definitely wants to tilt (as mentioned by some people earlier in this thread), the moments when the front would suddenly track off course don’t seem to be connected to this. I’m at a loss as to what’s causing this…I have no problems going straight in my 12-ft recreational boat, which I’ve been paddling for 4 years. People who would know have complimented me on my stroke, so I don’t know that I’m doing something wrong with that. I’ll just be paddling along and…whoops. The nose veers off course. I was constantly having to edge and correct to get back on course last night. The only thing the skeg seems to do is make it that much harder to steer back ON course, from what I can see.

Any advice would be appreciated.

Move the seat back to, “With the first adjustment, the directional stability seemed to get better, somewhat.”

When the boat veered off course what was the wind and wave direction in relation to the boat.?

The skeg’s job is to force the kayak more downwind. It is not there to make the kayak keep its direction better in all wind directions.

If you felt the skeg working against you when you were trying to force the kayak upwind, the skeg behaved just as it should.

Also, it is not clear to me whether your kayak went more downwind or more upwind than you wanted. I understand from your comment that you were not paddling straight into the wind (“headwind at times”) but rather into’ish the wind. This is in line with nickrowhurst’s suggestions earlier in this thread. However, when you do that experiment, you can’t just focus on whether you are keeping your course or not. You have to consider if your kayak seeks into the wind or away from the wind when it deviates from your intended course. It is quite possible that you started with a seat position where the kayak would seek too much away from the wind, then found a seat position where it was generally neutral and then continued the adjustment in the same direction until the kayak would seek too much into the wind.

Am curious how far the skeg was deployed. Fully? Half? Quarter?

You know too that, like sailing, sometimes your heading is different than your course. Sometimes sneaking up on a point is easier than a direct straight course. You can fight waves and wind or you can “tack” and sneak up on the intended destination.

For example my Cheasapeake 17 loves to go into the wind and wave from dead on to a 45 degree. It too will go down wind real good with some surfing, depending upon load. So I can fight a beam on wind and wave or do a 45 degree off the wind until I get high on the destination then turn the boat to a down wind.

Wind and waves are not constant in velocity or size or direction. It is possible that at times your boat was hit with a combination of forces that turned the boat when other times it was stable on course. Every boat has a personality.

My first priority would be to position the seat where it would allow easy ingress and egress to the boat in the fashion I am used to. Then I would adjust the seat for trim as long as it didn’t interfere with ease of getting in and out of the boat. As for the boat not tracking, get used to using the skeg to some degree–even when going to windward if needed. There will be times when you will also need to edge and paddle shift and maybe even use less than a symmetric stroke. All of that will be automatic in time.

What direction was the wind coming from? That will push the stern around, which of course also reorients the bow. More skeg means it will react less to the wind, though every model is individual on the details of how much.

This may sound stupid but I’ll say it anyway just in case. Thermoform kayaks can warp if stored outside in direct sunlight. Have you checked to make sure your hull is straight? This could be an issue.

Okay, let’s go through these sequentially. BTW, thanks for the replies.

DrowningDave: The kayak is about a week old and has never been stored outside at all. So I’m thinking warpage isn’t an issue.

Celia: The wind, when there was some, was coming more or less toward me from the front while I was doing the steps Nickcrowhurst listed. I noticed the inability to keep the kayak on course both in that situation, during/after my adjustments, and also when I was paddling back upriver, when the wind would’ve been at my back. It was a very slight breeze, FWIW. And the river has basically no discernible current where I paddle.

magooch: I’ve been paddling for about four years now, quite a lot. So I’m familiar with the requirement to asymmetrically paddle at times. I was using the skeg off and on during this afternoon’s paddle, mostly fully deployed when down, but toward the end I started experimenting with just partially. I can’t say I noticed a lot of difference in how the boat stayed tracking straight. As I mentioned, it DID create a lot of resistance when I tried to edge the boat back on course, however.

Overstreet: I’m not familiar with anything about sailing, but your statements make sense. My only question would be, why would I not experience these things when I paddled my 12-ft Pungo? It seems to me (and I could be totally wrong here) that a wider, more piggish boat would be pushed around MORE by the conditions you mentioned, no? I thought half the point of a sea kayak’s hull design was its ability to track straight?

Allan Olesen: Your statements confuse me the most, mostly because I don’t understand the terms “downwind” and “upwind” in this context. I don’t know what you mean when you say “the kayak pushed upwind”. I tend to categorize wind as “in my face” or some direction similar to that, or “coming across my boat” from one side of the other, or “a tailwind”. I suppose I’d better do some googling if these terms are important when discussing paddling.

Several of you asked questions pertaining to the exact wind direction and even wave directions, and I honestly don’t know how I’d even determine that without a windsock I could stare at. I’m paddling on/around Lake Erie and the wind and waves (waves, especially) are all OVER the place. And even when the wind is constant, knowing if it’s perfectly aligned with my direction is something I’m unable to determine accurately at this stage, I’m afraid.

“Piggish boat” vs Performance boat…? If the new boat is lighter, faster and more nimble maybe you have to act sooner to change than react on a piggish boat .

“Seakayak” does not mean the same thing in every boat. Generally they have floatation chambers fore and aft. But Greenland skin on frame don’t. Touring boats generally have less rocker and go straighter, but not necessarily. A Valley Etain is a touring boat but has more rocker than my C-17. It behaves differently. Banana boats (lots of rocker) are made for waves and turns. they’re all seakayaks.

To help some with the wind questions - most sea kayaks are designed to respond to wind by the stern being pushed and the bow going into the wind. A skeg or a rudder can counter balance this tendency to varying degrees depending on the boat, but that is the default for pretty all the kayak designs out there. That is because bow into the wind, if the paddler is having trouble controlling the boat, is considered to be a safer way for the boat to go off a straight course than the other way around.
So if you are going off course to the right as you paddle and the boat is otherwise being paddled straight, the wind is coming from your left to some degree and shoving your stern left. It doesn’t have to be straight left, it can be at an angle, say quartering.
This help?
