1980 Green canoe made by the White CO

I have a 1980 green canoe made by the White Company, that i register last year after i was able to confirm the make and model thanks to some of you here, so thank you for that.

Now recently we had a very strong wind in the area that i live in and the wind picked up the canoe from where i had it mounted and lift it over a fan and end up smashing into the back of my neighbors pick up truck. After paying for the damage now im left off with the gunwale destroyed.
Im looking for the best and most economic possible way to replace the gunwale because it shatter in multiple location making it useless. Any suggestion? i have watch many youtube videos and trying to find a place that i can buy the gunwales or make one if it requires minimal knowledge.
Thanks in advance for the help
