True Story

You're probably right.

Possibly, but they're Stainless Steel. Seems like an expense to cover a hole. Thanks guys, I'll keep snooping.

You just jogged my memory....the downriggers were called Fishlander. Possibly they had a planer board apparatus as well. The Fishlander bases were round as well.

The boat is a Wellcraft Coastal 252. They're is one on each side and is not original to the boat. They aren't vents and it isn't for a T-top structure. The original owner was a fisherman apparently, as there were old set of downriggers on the boat when I bought it. I can't remember the name of the riggers....it was some Michigan made off-brand that used Big Jon motors. The bases are situated midship, where either a planer board contraption, or maybe a rod tree would be situated. They certainly aren't original to Wellcraft. I've searched and searched and can't figure it out.

Help Me identify this base I bought my boat used a few years ago. I have no clue what this base is for. Can anyone help identify this?
