This is a prototype seat shell that I've fabricated using the offcuts of Australian Red Cedar and Huon Pine.
It's based on a rowing scull seat and, as such, it looks to be completely impractical for long-distance kayaking where lots of cushioning surface area is usually considered to be the best solution ... but, having cut a finger off in the process, I'm going to press on and give it a go anyway. It's yet to have an impact-resisting layer of Mini-cel foam laid onto it which should improve its performance.
It's certainly comfortable to sit on as it was tailor made to fit.
Not pictured is the back support and hip braces that I've also made using the same timber species. All of the timber surfaces will be resin-coated.
If this seat does not prove to be a good solution then I'll be carving a new one from a block of Mini-cel foam somewhere further into the future.
