Hunt is that a Shrew or a JavaMan bow? VERY nice.
I think it all depends on how far you can lean over the rail, haha. I would think a good bit less than 64" would be ideal for most, prolly more like 60", 60" is a nice length for ease of movement but still smooth to pull.
I just got a 52" Toelke Kestrel for a thick brush bow, it's 48" strung! It's like a 53# version of a kids bow, but pulls smooth to 29". Doesn't seem good to shoot much past 20 yards stability wise, but a bow that short is meant for up close and personal.
I will say other than the Kestrel, all my go-to's are 66"+, I love a long long bow. 6' 2" here.
