My tower is an Origin OWT-I. It was the cheapest tower I could find that looked decent. I ended up with a black tower. Whatever tower you end up with, make sure it will work with the beam on your boat. Most are pretty universal but if your boat is particularly wide or narrow it may not. Also make sure to follow the manufacturer's directions on backing plates. I did not need backing plates for my boat but you may depending on how thick your fiberglass is where you mount the tower. Some towers include them and some charge extra. You could also fabricate them yourself if you need them. Also, when you get to mounting the tower, taping off where you need to drill, drilling backwards through the gelcoat layer and countersinking your holes will help protect your gelcoat from spider cracking.
