Re: [electricboats] Newbie - 20+ foot boat for wide/long river in Guyana, South America

I'm an advocate for electric propulsion. Before being able to offer any suggestions, one needs a bit more info.

1. How big a boat are you considering?
2. What speed do you want to go and for how long?
3. Budget?
4. Excess solar power for charging?

Most likely the battery will be the most expensive component. You can build your own using cells from Winston or other manufacturer - no more difficult than doing model trains as a youth.

The major outboard manufacturers are just beginning to offer electric outboards. Torqeedo has a variety of products - both outboard and inboard.

It's easier to go slow - but speed can be done with modest distances/operating time.

As an example, my 12m cruising cat has a 1,000AH/48v LFP battery using Winston cells and weighs close to 1,500#. My two 10kW motors can cruise for 5 hours at 5 knots.

Best wishes,
