Bought a sit on top, want to attach a rod holder.

Hey guys. Picked up a sit on top to try out kayaking and some fishing as well, but its real bare bones and I'd like to add a rod holder. However, I'm not sure what holder to add.. and really where to put it (maybe on that center rectangle).

This is the yak I bought:http://www.samsclub.com/sams/hydros-kayak-blue-glacier-blue-kayak/prod18070079.ip?origin=item_page.rr3&campaign=rr&sn=CategorySiloedViewCP&campaign_data=prod16980074

Thanks for any feedback.

edit - I plan on baitcasting to start, but will also like to fly fish from the yak if that helps.
