R23 leans to port while underway.

[Whynot?]

Hello All
Anyone out there notice your R23 wants to lean off to port when underway. 10kt and above Very annoying. Always have to trim down the starboard side to get her balanced.
Hope someone out there has the same issue. And maybe a Fix.

Thanks
Chris

I can't imagine a fix. It's simply how she's made. Annoying? Yes. I find just the opposite, however... while cruising very slowly (10 knots and below), there is little that can be done, except have the first mate and any add'l crew stay starboard as much as possible.

Above 10kts, the trim tabs negate any need for crew to help stabilize. It's a matter of getting used to it. After just under a year of ownership, it's now second-nature.

We have the 9.9 kicker mounted, and that's on the port side, so that certainly doesn't help. But we've learned to stow as much on the starboard side as possible as to minimize the list.

While I wish she were perfectly balanced... our R23 is one of our favorite boats to date. I hope you get used to these eccentricities as we have and just have fun!

Taking a wild guess from my airplane experience, It may be the torque related to the prop turning. With that said, use of the trim tabs is exactly typical to offset variances from port and starboard. They are not always adjusted the same. Bennett actually makes an add on that will adjust automatically.

More a question than an answer, but I wonder what effect the weight of fuel and water aboard has on the boat's list at the dock and underway. Assuming the tanks are centered side-to-side and are in the bilge, would keeping them full reduce the famous port list by making the boat's center of gravity lower and more centered than it would be with empty tanks? Any naval architects out there?

I have the R27-OB, and the boat always listed (past-tense) to the port side.
2 house batteries, 1 thruster battery (about 70lbs each), the cabin refrigerator, we added the cockpit refrigerator (about 50 lbs) and the 9.9HP Yamaha kicker (about 100lbs). ALL on the port side. Of course it listed.

I upgraded the house batteries to Firefly Oasis G31's for an additional 20% capacity out of the same two 110Ah batteries.

Then I also relocated/moved the house bank from the port lazarette to the center cockpit lazarette. This gives me a port and stbd house battery, so they balance each other out. It moved 150lbs of batteries from port to centerline. The boat rides much more level now below 10kts. It still lists a bit when on plane but that's due primarily to the prop rotation and is easily balanced with trim tabs.

We were looking for more battery capacity, easier access to the batteries for maintenance, and we wanted the boat to sit more level when at the dock and when traveling at 10kts or less.

Hi Martin
Thanks for sharing your experience in handling your R27. Will try to shift a couple heavier items around to accomplish what you have done.

I have an R27 2018 with 180 miles on the Yamaha 300 when I get it on the plane I just tap my port tab down and balance that baby out however I around 30 MPH. Anyway that's my two cents unless someone wants to raise it to 19 cents lol

What did you need to do to accomplish moving these batteries? are the wiring harnesses easy to move over and are they long enough or did you need to modify them? Did you need to build a new battery box and if so could you describe what you built for each battery?

Love the videos on YouTube. Thanks for posting here as well; the details on tug nuts are always a bit deeper and better

Short answer, not really. I have the fuel tanks and water typically full. Our R-23 seems to list when there are people on-board. Typically, if it's just me and the wife, the R-23 does fine as long as we both are not on the same side. When we both sit at the dinette, then the boat does list to port. When underway, I am able to level the boat even when there are 3 people sitting at the dinette. The narrow beam, a/c, microwave, 3 batteries, dinette all on port doesn't help of course. But, we still love the boat and simply adjust to it as Brian mentioned above. When we travel overnight to another location and actually sleep onboard, I put as much of the weight on the starboard side - coolers, overnight bags, etc. Cheers! -Norm

Thanks for watching our video's!! The youtube channel is mostly all LaZina. She's the producer, editor-in-chief... We're releasing video's weekly, and surprisingly enough (being off-season), have content that covers the next 4 weeks.
- Power Management
- Battery Upgrade/Relocation
- How we winterized on the water so we can use our boat all year.
- Electronics - Some of what I've done with the Garmin and how we use it.

And our 200 hr maintenance is only 20 hours away. We're going to do complete video on that in December before it gets really really cold outside.

Kind of the final straw for us was when one of our marina neighbors came over and said "I was looking at your boat the other day and I was going to give you a call, but couldn't find your contact info (we didn't have it posted on the window), as I noticed the boat was listing to port". We noticed it, and so did everybody else.

The upcoming video about moving the batteries will illustrate this really well, but at high-level... I pulled the two house batteries out of the port lazarette, moved the thruster battery to the stern most position in the port lazarette. I installed a + and - bus bar, to connect the boat's electrical loads to in the spot where the middle battery would have been. I didn't want to have to remake any cables that came with the boat. Ranger did a great job of labeling all that, and I saw no need to alter them. Then I ran 4/0 cable from the + and - bus bars to the new batteries located in the center cockpit lazarette. Wired it up through my shunt for my battery monitor, added a 350amp fuse for the cable I added. The batteries are secured in battery boxes that are held down with ratchet tie down straps. They're not moving.

It was a full day of shopping for all the parts (had to hit several marine shops to get everything), and another full day of doing the work. The boat noticeably rides level with my wife and I onboard just cruising at less than 10kts.
