double bend canoe paddle

My Dad has developed a fixcation on owning a double bend canoe paddle. I plan on making it a Father’s Day present. He uses a 52 inch bent shaft for normal touring. I know nothing about double bends but figured the sizes should be the same. But, since I have figured wrong a time or two in the past I wanted to ask.Should the regular bent shaft and double bend paddle be the same length or does it fit more like a straight shaft? thanks, Ben

double bends
i paddle a 52 inch gillespie and really enjoy it. has a great feel to it. my zav is 51 inches and i can tell it’s shorter. i don’t think there’s much difference length-wise between a single bend and a double bend. maybe you could find out if he wants to go a little shorter or longer than the current paddles he owns and go from there.
