New Boat Leaning

[gibbs114]

I used my boat for the first time this past weekend and it has a lean to the right when the boat gets up to speed. The dealer checked it out and said they found a bubble in the hull causing the problem. Has anyone ever heard of this problem?

What do they mean by "bubble"? An excess of material causing a bulge? A lack of material causing an air pocket?

Either way, sounds like a warranty issue.

What speed was the boat leaning? Was it doing it all the time? What was your TAPS setting? Did changing the TAPS setting change the "pull" of the boat? The torque of the engine tries to twist the boat through the water and the amount of hull in the water counters the torque. You will feel a different pull of the boat at various speeds and TAPS settings, but if the dealer says its off, then I suspect it's off. Did they show you what the bubble was? Any pictures? You've got me vary curious.

Sounds like what is referred to as a "hook" in the hull. Most inboards have some hook built into the hull(not sure on the convex hull), but if one side has to much it will want to list over above planing speed. I had one years ago that was terrible. If you were in the boat by yourself above 30 mph it would list so bad it would start to do a slow arcing turn. Did the list(lean) get worse as the boat went faster?

How many people were in the boat? Where was everybody sitting at the time? Did you have any ballast filled or had you earlier?

This is gonna be good. I am interested to hear the details.

My 2013 RZ2 had a definite lean to the right last fall after I bought it. My dealer had it this winter and ended up having Tige tell them there was a "hook" in the hull that should have been sanded down after it came out of the mold. They have sanded it down, however, it will be a while until I get the boat out for the spring so I don't know if the problem has been fixed. My wife and kids along with all our heavier items were on the left with just me on the right. It was only noticeable when the boat was at cruising speed. There was also a slight bend in the TAPS plate which they thought could have been a contributing factor.

I have new 2014 RZ2 and when it is just me it has a distinct lean to the right when running. Is it normal to be that sensitive to uneven weight distribution or sound like the "hook" issue above?

[gibbs114]

Two people in the boat, taps on 2 but no change on any settings, notice the lean at about 18 to 20 mph no ballast in the boat, all they have said is that there is a bubble in the hull and will get it taken care of next week. I have a great dealer so I'm sure they will it just makes me mad being a brand new boat.

You'd think Tige has some nice scientific instruments to measure the hull after it comes out of the mold. There is no reason a ride on the lake should be what's finding this. I am also interested to hear how this unfolds. The good news is that they recognize the defect and are fixing it. Good on you for picking up on it.

Yes, the RZ2 and many boats this size are sensitive to uneven weight distribution. Another thing that could happen is passive filling of a ballast tank. Depending on how the boat is riding I used to get a little passive filling of my starboard hard tank. I just put one-way check valves on all my fill lines so that should add a little resistance to passive filling.

I don't feel like the boat was lake tested at the factory they would have noticed this very easy. I was told it can be fixed but if for some reason it can't be they will get me a new boat.

[boardman74]

Theoretically your boat should have been lake tested at least twice already. All the boats are water tested before they leave the factory. Then your dealer should have water tested the boat during the PDI. I'm sure it's something that will get fixed without issue. When I owned another brand boat that this happened to, it was far more severe then what you are describing, they fixed it no issue the first time. I am glad to hear that your dealer and Tige are on top of this and fixing it quickly. Thats how it should be!!

Gibbs, my RZ 2 has the same lean to the starboard side when up on plane. I have to counter it with weight in the port sacks and it drives me crazy. My 22 VE tracked extremely straight. There was a thread on here a year or two ago about this same issue and if I remember right they said it was thicker gel coat on one side vs the other. Could this be the same as the hook explanation? If all it takes is some sanding, I'll look into it. Please keep us up to date on what you find out. Have to agree this type of thing should not make it past the lake tests prior to delivery.

A hook is a "pocket" on the bottom of the hull at the stern edge. The water can't flow smoothly across it and gets caught in the hook, creating a lot of drag on that side. It causes that side to be pulled down. Opposite effect of a twin tab on a bottom rear corner of a hull. A combination of hook and rudder preloading is one of the things that give inboards very precise immediate steering. Most inboard hulls are designed with some hook on one side or the other. Not sure if the Tige hulls are or aren't.
