I'm surprised he hasn't just added tempera ballast but to view the video he dose seem to be riding pretty high

Wait....
1) A lot of the big old cruiser wallow at slow speed - they did that with their original power plants (diesel or gas) too!!!! My '84 Sea Ray 270's wallowed badly below about 7-8mph. My buddy's '89 does the same. My old '95 Bayliner Ciera 24 did the same. These boats are designed to plane, not go slow. Adding weight might not help at all!!! A big skeg or fin might.
2) If you really think it's a *weight* issue, there are MUCH faster and cheaper ways to test that out than adding batteries!!! Put a 55 gallon drum in the back and fill it up with water, or just buy a couple of cases of beer and invite some friends over.
If you were to find that you really needed a lot more weight, then I guess golf cart batteries would be a good way to go. :)

You are absolutely right big old cruisers can be had cheap. I'm following a gent on utube who may actually be on here if he is I hope he responds. He did a very reasonably priced conversion but found that the boat handles very poorly because he lost so much weight. It tends to wollow badly. I believe his long term plans when he can afford it is to add a large battery bank to get back to design weight.

Right, and the original poster acknowledged that he probably wasn't ever going to get on plane.
But there are a lot of old cruisers out there with questionable motors / outdrives, etc... It would be nice to think that one could buy a cheap old cruiser (or especially a trawler!!), replace the engine with an electric, and have a much simpler power train to work with.
The first issue is you wouldn't have a lot of range. Though on my inland lake, I know of a LOT of cruisers that go from the dock to the cove across the way, anchor for the day, and come back. These boats have more hours on their gensets (for margaritas, ice, cold beer, and AC for the head) than they do on their engines. So if the boat is basically a floating hotel / party platform, and you only motor over to the pump out dock, or to a nearby cove, maybe... We have seen that it's very practical to power a 30+ foot sailboat off batteries, albeit at slow speed, for a couple of hours. A cruiser is a lot "fatter", but if you are ok going slow, you could still do it.
And then there's the generator. If you can find a HUGE power supply to convert the genset output to the right voltage for your electric drive, then you'd be in business. And then, instead of maintaining on or two engines, you're mostly worried about one generator.
Though in PRACTICAL terms.... you may still be better off repowering with gas / diesel.

I know how projects multiply! I may be wrong, but I do not think electric drive has progressed to the point of planing in a 26' boat. That requires much hp to get it on plane, which means a very big motor or two. They would deplete the batteries pretty fast. Keeping it at displacement speeds may be more practical.
