Angled aluminum bracket for hanging canoe seat below gunwales.
Sold as each.  Need 2 to hang a seat.
Specify the depth of your seat.  Most seats are either 9.5", 10.25", or 11.5" from front to back.

Uncut option is flat along the top and needs to be cut to match the angle of your gunwale and the desired drop of your seat.
Other options are cut at the top of the bracket to match the angle of the gunwale for that canoe model with about 3-4" of drop.
