I've seen a lot of people with this type of boat. I've been watching a lot of Youtube videos and I see a lot of these being used. Have you done a search to see what the specs may be?
Here's what I found on that type of boat
Specifications- Length: 15 feet, 7.5 inches
- Width: 29 inches
- Seat width: 17 inches
- Weight: 60 pounds
- Maximum weight capacity: 550 pounds
For me I would like a little more width, but I'm sure the tracking, and everything else would make up for the width.

Here's the link that I went to. For $700 it's not a bad looking boat.
