Sam's has a group 31 AGM marine battery that I have been using for years. They are roughly $170 or so.

Thanks Jason and Rick. Trying to determine if I should go with a combo battery like Jason’s or deep cycle vs. starting. I have starting batteries now for the Cummins but two are tired.

They are expensive - but I went with two of the ODYSSEY 31-PC2150S Heavy Duty batteries. In Florida the heat kills the batteries and I have had good luck with the Odysseys - typically getting twice the lifetime out of them, even the Sams AGM Marine Duracell (if you can find them)

I generally change out my Sams AGMs every 3 years and give the old batteries away. Many times the next guys is still using them a couple of years later.

Keep in mind I'm using them in a CC with twins OBs. Its hard to get batteries in the Family Islands in the Bahamas and you don't want to break down out there.

Rick my old batteries were from 2017 (same ones) and still good I just replaced because everything was new! With the port supply account they are pretty heavily discounted.

I have been trying to get stuff done but it is slow going today I finished up mounting exhaust. Most of the wiring I need to just get floating is done. Soda blasting was done this week now for the repairs and barrier coat and bottom paint It would be nice to splash this year just for shake down purposes. Not to mention my sanity it’s been a lot of work not to mention $$$$$ . Image Image [url=https://imgur.com/cVrSMLx]ImageImage[/url] Image Image Image Image Image

Tony, Not to bad I could have left a little more room for exhaust wrap it is a little tight but I got it in there. Slowly coming along now on to the bottom. See if I can get this thing floating soon.

Looking great, I hope to see you out there this year!

One warning, if you decide to splash earlier than "done" it may wind up staying "not quite done" as the work takes a backseat to just enjoying for the rest of the season.
I had full expectations of hauling after my initial sea trial...if I made it out of the well, if I made it past my slip, if I made it past my marina, the harbor entrance, to the Buglight marking the channel...but the boat did and found itself in my slip tied up and ready for another day; there she stayed till the weather got cold.
I kinda stayed that way till this year and we are just starting to toy with the interior...just now making minor upgrades to make her presentable and useable although we have been using all along. But used kinda like having the holidays in a home with a renovation project going on.

Jason-

Oh, you earned a break and should reap the fruits of your work in my opinion!

For me, a splash with a good ride would recharge my batteries, giving me new energy to continue.

And if the boat is left in the water....working on a boat in the water is not the work it is on land. On land the work IS WORK, in the water I find the work has an enjoyable aspect to it...almost therapeutic and I do need therapy.

That said...in the water production and progress can dwindle some.

John thanks! I got a used set of 21x24 Michigan going to start with them. I think they will be a little big but it gives me a starting point. I have talked to someone with the same set up and he is running 20x24 and they are a little small so we will see.

Bottom is done five coats of barrier three coats of bottom paint. Started on the rub rail almost done. This was not the easiest job for sure. I bought it from Danny at high tide and had the corners and bow pre bent. The bow fit ok but corners were unusable i had to cut and miter them thankfully i had enough material to do it. The rail didn’t fit to the boat it wasn’t deep enough i had to grind the whole flange down to make it work. It came out pretty good but once again it was not easy! Should be close to sea trial day soon. ImageImageImageImageImage

Hey Jason, it’s a Bertram 31! They were all built a little, umm, differently? Your rebuild looks top notch. I’m constantly impressed by the talent I see on this forum.

Thanks amberjack I agree they can vary a little from boat to boat. No complaints really it is nice when finished for sure. I Remember a post Capt pat made that said Danny’s rail was for a 46 and wasn’t exactly like stock he also stated the corners couldn’t be bent and had to be mitered. Just trying to help any other guys that are going to tackle this. Nothing that I have done has been plug and play so far but I like the challenges.

Well I launched Friday and got to do some trials over the weekend as well as some rafting up with friends. I am not done yet but for my sanity I had to go for a ride. The boat performed well I have more work to do but the initial shakedown was great. I have to check the tachometers for accuracy it they are right I might be slightly over propped. There were four guys on board and 200 gal of fuel I ordered a photo tac and will conduct some tests later this week. Right now I make 35 knots wot port engine is 2800 rpm’s and starboard is 2950 rpm’s
At 2400 rpm’s I am around 29.8 knots more pictures and test results to come! It felt amazing to finally take a ride after almost five years!! Image Image Image Image Image Image

Jason - Awesome news, so glad you were able to get out and run her! I'm sure it has to feel good knowing what you have attained.


I must have missed your sea trial by only a few minutes on Friday. Would have been great to see you fly by...and you would have. We were heading up to the Patton Point Club for the weekend, we got the sea brite bridge for the 7pm opening, so passed highland about 5:30- 6. Hard to tell against the current at no wake. Returned about the same time Sunday...almost headed into the highlands for a swim...but kinda done with boating by then.

The family sure looks happy to have a boat with a wet bottom!

Still working on the boat but I can’t wait to be back in the water. My marina is doing a new bulked so I have to wait till June 1st. I finished up all the wiring this winter and some other projects. Had to pull the shafts out and have Carl get some new couplings fit them for me. That’s all back together now. Big thanks to Carl they came out great! Just started the sound down in the engine spaces. Image Image Image Image Image Image Image Image Image Image Image ImageImageImage Image

Thanks guys! Yannis I separated the cabin bilge from the aft bilge to keep it dry and clean. It also keeps he smells out. I still have a bunch of work to do but I can definitely see the light at the end of the tunnel. As you all know it will never stop there is always something to do. Repairs to engine boxes and prep for paint is what’s happening now.

When I bought my boat it had a tuna tower installed and the corners of the engine boxes were cut off so I had to glass them back on. I wanted to do that so I can paint them before I install the sound down on them. The plan was to throw a quick paint job on the windshield and the gunnels and decks but I am running out of time. I was going to try and fix the non skid pattern on top of the boxes but I think it will be a pain so I am thinking just sand it smooth. I want to put cushions there at some point anyway.

Jason,

The non skid on the boxes looks fine, why touch it?
If you put cushions it’s gonna be perfect.
Just touch the corners with some paint now and after the summer you will see...

I agree with Yannis. Just make a nice even smooth triangle on the corner of each. As long as it is symmetrical it will probably look fine. Unless that will bug you to death . . .
