I am wanting to replace the rotten wood gunwales and decks on a 1988 Mad River Malecite. I know Ed's knockdown system is virtually the only reasonable priced option but I am famously frugal and always curious about pros and cons of cheaper options. I know hardwoods are preferred but is it just because of their impact resistance (won't dent) on impacts? If you are paddling mostly flatwater and don't expect rough useage,..why wouldn't fine-grained 16ft strips of pine work? The 5/4 thick 2x6x16ft decking sold at lumber outlets that already have the rounded edges would have the perfect dimensions if it were run down a tablesaw to make 3/4 inch strips on both edges. Two $8 boards could complete a set of gunwales. I know they are pressure treated so not sure about long term preservation but HECK its made to last outdoors, exposed to sun and rain continously for many years. Any thoughts? No need to tell me I am a cheapo,..I admit it!
