A canoe with external thrusters

[douban]

Hello everyone, this year I suddenly wanted to build a flat tailed canoe. It's not just pointed on both sides, but with a 90 centimeter V-shaped bottom on one side, rounded in the middle, and flat at the tail to facilitate the installation of thrusters. However, I haven't found any similar canoe construction messages on the forum. I don't know if you have any similar links or pictures for me to refer to. You know that few people in China play canoes, and sometimes they have some ideas but dare not boldly implement them. Thank you very much

By searching, I found out that it should be called a cargo ship canoe or a square tailed canoe. What I want to know is whether it will overturn or capsize at high speeds, and whether its narrowest point should be several centimeters, because I don't have any drawings. However, I have a template for a previous canoe that can be from 4.5 meters to 5 meters in length, but the widest point of the template is only 90 centimeters. If I want to build a cargo ship canoe that is 4 meters long and 1 meter wide, is this idea practical because I am afraid it will overturn at high speeds

They're termed "square stern" around here and @memaquay has built at least one that he powers with an outboard motor.

As for flipping it: Higher speeds increase the risk of overturning on any type of boat but I have no idea how to minimize the risk except to keep speed within your risk tolerance. Just because you have a 5 horsepower engine (for example) doesn't mean you have to twist the throttle all the way to the stop.

20 foot freighter canoe

Been thinking about building a freighter canoe for a long time. When I lived on a reserve up north, the 20 to 24 foot freighter was the standard boat of choice. They were all wood/canvas canoes, functional and beautiful. So I first found some plans that looked like they had been lofted from a...
