I did wonder if it was for a dinghy bracket that just drops in but cannot find one.
i don't doubt you have and almost all have two per chock.Definitely not dinghy chocks as they have 2 sockets for each chock have seen loads of them.
What- to stop people falling into an 8 inch deep tray moulding?I wonder if there's another/additional purpose ? Insert a removable stanchion into the socket each side of the hatch, with a line or light chain leading to the eye on the for'd end of the platform; could prevent people walking down the open hatch ?
What, and it wouldn't be possible to offset the tongue with a 25mm x 25mm or whatever offsetter piece?No I don't think they are for chocks as the tongues as you propose would not be in alignment with the hatch aperture, I suppose they could take temp handrail as Sarabande suggests
H frame jet ski / tender holder .
The two holes connect width ways with like a H to support what ever .
You would not fish ,ie place a rod there ,it’s too dangerous ,wave backing up , or large sea creatures flying up and potentially knocking you off .
