Need help identifying track system

[Jackp]

Last year I bought used 2022 18ft aluminum boat in WA state. I’d like to add new accessory mounts for its track system but I cannot figure what kind of track system it is. Has anyone seen this product before ? It resembles T-track system but the slot is wider Any thoughts appreciated.

Hmm, I looked through a number of marine catalogues and couldn't find anything comparable. I wonder if it is integral to the boat?
