Have you thought about using pro video camera batteries that are 14.4 volts and only weigh about 1.5 pounds each. They’re considerably less expensive and they are LiOn. You’d have to modify the brackets and probably connect them in series or use a step up transformer? Just a thought.Motors are Ride on Scooter motors that require 24 volt batteries to run, here is one while I fit the mounts which will be glassed in. The prop shaft is continuous from the motor room bulkhead to the prop itself which makes the A bracket visual only, the shafts are totally to scale but enclosed over whole length so luckily it was possible on this ship, basically its the same setup as a smaller model, a shaft with bronze bearings at each end and a grease nipple in top.
the rest is all visual to make it look proper.
I was going to use 4 x12 volt batteries about 8 AH but am considering Lithium packs now, just scared of fire risk...not to mention 24v Lithium batteries are between $1000-2000 each.
Believe it or not the finding the batteries has been the hardest part of this build for me..so if anyone has suggestions please shoot.
Here are the motor specs.
I should add the motor specs were given to me by the guy who built the props, as I am not great at that sort of thing.

30 years ago I could have calculated that. Now, well …
Here’s the specs on this particular battery pack. I’ve not used this particular one, but the specs will be similar. There’s larger packs with more Watt hours and of course more money. I’ve used similar brands and at the time I bought them (new) they were at least twice as much.
I have bought lots of equipment from B&H and their other store, Adorama and if I was in the market for pro video/still photo equipment I’d do business with them again. I would imagine that there’s probably some really good video/photo places nearby…after all Peter Jackson created a masterpiece in your “neighborhood”!
Featuring a 99Wh capacity, the Mini Brick is suitable for short to mid-level shoots as far as runtime, depending on your camera. Used with a small mirrorless camera, it will certainly multiply the runtime you would normally get with the camera's standard battery. When the battery is in use, the remaining battery capacity is displayed on a backlit LCD that's located on the rear of the battery where it's easily visible during a shoot. When the battery is being charged, the LCD shows the remaining charge time.
The Mini Brick also features four accessory ports, three of them for powering accessories and one for charging the battery. A D-Tap output allows you to power an accessory, such as a monitor or light, simultaneously with your camera. (The D-Tap output supports up to a 10A draw.) USB-A and USB-C outputs let you power and charge mobile devices on set, such as smartphones. And a USB-C input can be used to recharge the battery over a USB cable as an alternative to using a V-mount charger. Two USB cables are included with the battery.
The battery supports up to a 13A continuous draw, so it can power up to some of the most power-hungry cameras and lights if you ever need to. Such a high draw isn't too common in batteries that have around a 100Wh capacity. Most generally go up to 10A (or even 8A).
To help maintain the lifespan of the battery, a built-in intelligent control circuit protects against damage from current or voltage overload, overheating, or short circuits.

Features
The Pawa Mini Brick 99Wh Lithium-Ion V-Mount Batteryhas a standard-size V-mount in a compact form factor that provides a lot of benefits. The smaller size makes it easier to pair the battery with smaller camera setups and with gimbals and drones. The smaller size is also beneficial to more common setups, simply because the battery is substantially lighter this way. Pawa also blends the compact size with a modern design for a sleek, contemporary look.Featuring a 99Wh capacity, the Mini Brick is suitable for short to mid-level shoots as far as runtime, depending on your camera.

Thanks, I will see if i can find out about this info.
Yeah its going to be a bit of a deal when it goes in the pond the first time, even my dentist has asked to be there. we built a water feature onto our house last year, it's a "pond" with a waterfall at one end, and good for dogs to cool down, the fact that it is 5.5 m long and 800mm wide is complete coincidence I promise..... yeah no it's also a test tank. I can avoid any embarrassing problems now before that day
What to do if the bath is no longer big enough!
As I said, having a wonderful wife is a big help.

I totally agree about having a wonderful wife. Your pond is impressive. Your copper work is also impressive. I only recently started working with PEB, it’s been fun learning how not to do something. I’m a firm believer in learning something new every day! I get lots of inspiration here on SOS, hopefully I remember what I learned and put that knowledge into practice.
removed, was in wrong build

Richard,
To say that your work is impressive is an understatement. You have my respect for tackling this project for such a long time. I can understand your passion. The only wooden boat that I’ve made was a US Coast Guard Life Boat from a Dumas kit. I had zero experience working with wood at the time. That project took me 10 years to finish and then I lost it in a move across country… about the same distance between NZ and Sydney. Since then I spent another 10 years concentrating on my career. About 3 years ago I was determined to start building models again, but plastic because we moved from our house to an apartment with no workshop. Plastic was and is still rewarding to me because I concentrate on the end result and enjoy the journey getting there.
You’ve mentioned that you build or built guitars? What type? My son and daughter in law are both very talented musicians, my son plays guitar…. Electric and acoustic, piano and keyboard… he’s adept at playing most styles: rock, jazz, pop, etc. His wife also plays piano and guitar and sings. Me…. At this stage I play audience and videographer and photographer. My wife…. Well she’s an inspiration to us all… she sings, plays piano and is one of the best tv journalists I’ve ever worked with. Long 43 year story!
Did many overnight sailings Wellington to Lyttleton and returns on her. Most enjoyable and some fairly rough Cook Strait crossings but all fun when one is a teenager

View attachment 418633They look like Gibson’s. Beautiful guitars. Scott’s got about 8 guitars at this point. Gibson is one, the rest are a variety of Fenders. I’ve been threatening to buy him a Dobro or a pedal steel for his birthday but since they have a brand new musician, only 7 months old, he probably won’t have time for a while to get proficient for a while.
This is really a GREAT project - and highly interesting - completely different and unusual - I love it already
After leaving the styrene for 18 months to see if it stays bonded to the hull in our extreme temeperatures I can report indeed it has, we have gone from 5 to 38 c over that time and it does not come off unless I chisel it off bit by bit. I can safely say I am safe to proceed again. Only with the proper commercial cyano "Starbond" though which is amazing stuff.
This is amazing work. How do you plan to mover her once ready ? Would you need to build a custom trailer ?
Yes I have a trailer designed ready to get built, the lake where this will run is not far from here luckily, 5km or 3 miles
