This is what I use. Hangs off the side of the boat, then folds up flat for storage. Works great.

very Slik indeed !! i have the same concept , but had a plexiglass outfit make me one outta 1/4 in material ,
bent the same v as yours it looks like , then a cutting board poly type material cut up to close off the ends ,
held together with small 1 in inch stainless steel screws , pre drilled so it wouldnt crack ,
left a one inch gap in the deepest part of the pocket so guts and blood could flow freely ,
as fins boat , looks like hes filled his lower rod storage ports , i still utilize mine , i store my harpoons in there..
i use adjustable locking straps looped around my top harpoon to prevent my v cleaning station from falling over board ,
or mainly getting the perfect hanging height , when done ,rinse off with the washdown , unstrap , stow away below , ezpz ,
prefer the over the side concept , keep most of the blood bath outside the boat ,but best , holds the fish well , doesnt need ta be flat calm ta use,,
see if i can post a pic , use it all the time when were on the hook for a night or 3
its at my trailer right now , goin next week fora fish...
cheers
