Run a few select racks up that blowboater's mast on his lines.

It's marina rules as far as I know. My marina doesn't allow fish cleaning remnants in the water either....gotta put in double bagged trash bags and throw in dumpster. Sometimes lobsterman/periwinklers put S closed top poly drum near the fillet station for carcass donations for their bait. Man does that barrel get ripe!

My marina just doesn't want the seagulls to fly racks and skins up onto other marina boaters' boats.....plus there is a town swimming beach just 100yds or so away from our fillet station.
