Does your boat lean to one side while sitting still in the water?
I have an 1986 20ft bayliner cuddy and I've noticed a slight lean to the right.
I had to deal with wet foam undeer the flooring that I mentioned in another thread. Prior to removing the foam, I had a bad lean to the right as that was the side with the most saturated foam. This was also causing major steering issues.

Now all the wet foam is out and the flooring is new, stringers, transom, etc is all good. I've been out several times since and I'm not taking in water anywhere. Still the boat leans ever so slightly to the right. However all the instability in steering is gone. Prior to removing the wet foam, I actually had to fight the wheel and it was down right unsafe.

I was surmising that the lean I feel is now because of the two large marine batteries located on that side of the boat in the rear. Also most of the controls; steering cables, dash, etc, are all located on the right side.

So I took the batteries and weighed them. 50lbs each for a total of 100lbs.
Doesn't seem like a lot of weight. I took and equal amount of weight (old weight machine weights) and put on the left side in a location equal to the batteries on the other side. That evened out the lean perfectly, except it's too much weight in the rear of the boat and the boat just doesn't feel right running above half throttle. It's also not sitting properly on the trailer because of all the weight in the rear. So this is not going to work.

What I think I'm going to have to do is install longer cables and move one of the batteries to the other side of the boat in order to resolve the issue.

My real question(s) is; Does your boat lean also? Is this "normal"? It's down to a real slight lean now, but it drives me nuts! There are several bayliners identical to mine in the marina that I launch from that I've noticed all have the same slight lean to the right. They're I/O models and mines the Force outboard though. Battery weight? I know the v-hull design lends itself to more sensitivity to roll or lean on the water. There is a large whale tail installed on the motor but I'm talking at a dead float.

I'm use to boats that sit perfectly flat in the water, so it's like I said, this drives me nuts. Is there something I'm missing here? There's no hull distortion that I can tell of. No spider webbing or cracking that would indicate a weak or over flexing hull. I just don't know. What's everybody else's experiences like? I see smaller boats coming in all the time with too many large people on board that don't seem to have this issue. Seriously, I saw a 16 footer come in with 6 people all over the 200 lb range the other night.

Have you looked at another Bayliner same year and model?

Try moving one battery, may just work.

Where is the fuel tank located?

If the weight isn't evenly distributed they all will lean, even the Queen Mary.

It?s a small weight boat and it doesn?t take much to upset the center of gravity. Move the one battery to the other side and that?s the best you can do.

What concerns me more is that you say the additional 100 lbs of weigh makes the boat handles uncomfortably above ? throttle. What do you do when you get people on board? Are you sure you don?t have other problems besides the foam?

And to answer your original question, my 22? boat sits pretty even at rest and my batteries are about 70lbs. each. But then again I?ve got a 8? beam.;)

You already answered your own question. Repeatedly. In your initial post.

where's the link?

You can get rid of that whaletail now that your saturated foam is gone.
With it gone, it should help your handling problem. Did you have to replace any rotten water logged stringers or do any transom work?
With controls, driver and batteries all on one side, you would have a little lean.
Before you move batteries you can balance your weight with a 100lb. friend. Just have her walk right to left while you watch the leveling from the back, in the water.

I was referring to having 30 people view the thread and no responses.

No rotten stringer or transom. I started this thread to try and figure out what else could be causing it to lean. I did put 100lbs of weight (equal to the batteries) on the opposite side. It did level out good, it just seemed to me like it was too much weight in the back end.

Yesterday I took the added weight back out and the lean was back. I had my father who weights 190 with me and if he stayed on the left side things were okay. But if he moved around, it would throw the balance off again.

I don't get it. It leans at a dead rest, so it's nothing to do with engine, etc.
Transom and stringers are excellent. The only difference that removing the wet foam made was that I don't have to fight the wheel anymore. That issue is gone. Funny that the foam on the left side was more wet than the right anyways, and all of the foam wasn't really that wet.

I'm going to be experimenting with battery placement and some weights this weekend. Weather permitting. I started this thread in case their was something someone knew about that I didn't know about concerning this make and model.

Thanks again.

Re: Does your boat have vertigo? (lean)

I too have a leaning boat. I bought a new 2007 Larson LXI 208 with 5.0 MPI and B3 drive, and it leans to the right while sitting empty in the water or while moving. If the water is absolutely like glass then I can trim up the motor too about 1/2 on the gauge and the boat will then run flat but this is very rare as usually it starts to porpoise while trimmed that high. Larson is telling me that I might have to ship the boat back to them (or a repair shop of their choice) and have the hull "shaved" down on the port side. I am not impressed with this solution as I purchased a "New" boat not one with a Factory defect to have hull modifications done in order to have it float level? I only have 1 battery in the boat and since it needs almost 200 lbs. on the passenger side to level the boat out (with no-one in the drivers side) then I can't see how this could be a weight distribution problem.........unless it is engine misalignment or fuel tank?? If I was a Larson warranty rep. I would just replace the boat with a new one then repair the defected boat and sell it as a used reconditioned boat. Please let me know if you find out why your boat leans and I will keep you informed about mine. Good Luck!

Don,t forget you on weight! Are you talking about when in motion? I think almost all boats lean a little. Adjustable trim tads will take care of any weight shifts when your in movement.Once you have them your spoiled. I am in the process of replacing my floor now, have a question about your old foam. Was if wet all the way through, or just the top 2 or 3 inches? I ask because mine is also wet.

Re: Does your boat have vertigo? (lean)

Put me on the leaning boat list also. I have a 88 20' stingray svc 207 ss cuddy 5.7 l . I purchaced this in the spring and noticed a slight lean to port side with 2 adults and 3 kids on board I then made sure the passengers were evend out to their body weight, then the lean got better. I then for the first time filled my fuel tank then the port side lean was verry evident when I trimed out even if I moved all my passenger to the oposite side.. I have now learned to operate on a 1/2 tank of fuel and if I start to lean( my 60 gal fuel tank is factory off center) I adjust with my trim taps this helps me.

Re: Does your boat have vertigo? (lean)

Got a leaner too. 2004 Scout Dorado, and like you, Swamp, it drives me nuts. Probably a half inch down on the starboard side when sitting or trolling speed. The answer was ridiculously simple. I have a single battery located as far off centre as you could get in one locker and its twin on the other side is...an empty livewell.

Problem is, I don't fish (although the I love quality and ergonomic design of the boat that's due to the influence of those that do) so there's never any water in it. One morning I was idling along enjoying a coffee and the sunrise, while obsessing over my half inch list. For the heck of it I flipped the aerator pump on and waited for the livewell to fill. Sure enough, the boat gradually attained even keel.

So, now any time I'm feeling especially anal I have a decision to make. Take fifty pounds of water on board and pay to cart it around on an even keel or get better gas mileage and put up with the list. So far I'm running about 80 percent on the Ta-hell-with-it-let's-jes-motor-as-she-be side of the ledger.

It is interesting, though, how we obsess with our own boats. I've probably seen a hundred Bayliner cuddies at various launches and I've never once noticed any of them listing. Not that they don't but it's just that I couldn't care in the slightest. My own boat, however, I can spot the slightest list from the end of the pier and I HATE it. But I'll bet no one else has noticed though cuz it ain't their baby. Boaters are nuts...
