Bought this for not exactly knowing its length & installed in on my TFL Pursuit. She is now wayyy better doing turns around the buoys.
True not that sharp but right now I did not noticed any drag with my boat but I may sharpened it in the future.
Good buy.Got the fins today and they are both the same size. You will need to finish sharpening them as there is a little bit of a flat spot on the edge of the fins. Though it is stated for a gas boat they will work fine for a 40-60 size nitro boat as well.
