Just curious if you can cut them Fiberglass 5/16 fish arrows down at all?

Only reason I ask is because I gap shoot and ALL my arrows are 28 1/2"...changing the length a 1/2" throws everything off and my aim would have to be re learned pretty much.  Not sure how stiff that would make em coming out of a 47#/53
# bows but I figure it would work somehow.

Unless you're shooting really good distances, I dont think itd make much of a difference.  And, since you have to train yourself to hold under the fish you are shooting at, all method of aiming you are used to using kinda goes out the window.

I bowfish with 45lb and 55lb recurves, as well as a 54lb longbow, and I see no difference in arrow flight with the uncut fish arrow.  But, I never need to take shots more than 10 yards while bowfishing, either.

Just my thoughts, though...someone else could have different experiences.

Ill still be aiming just aiming lower then normal to make sure i shoot under em

Cut em. I cut a bunch over the years.  But my bowfishing partners say it is obvious that I'm not aiming and the results are all the same

There's no need to cut them for reasons stated. But if it makes you feel better, they're your's do what you want with them. You can cut them with a fine tooth hacksaw.

Wrap them with tape to keep the end from splintering and splitting fibers off when you get almost through.  Wide scotch tape will do.  Bill

I only cut them when I need to when bareshaft tuning like other arrows.Longer is better if they shoot well.Longer gives you a closer point on and less gap.Longer is easier to get to when you whack a stump or hang up in roots on the bottom ect.

Tom, I cut ours with a hacksaw, you can use Gorilla glue to glue the nock and point on, just keep a look at it for the first half hour to make sure that every thing is in place with the expansion of the glue. Don't forget to use a safety slide on them
