A T-Top is an aluminum structure with 4 legs and an aluminum frame that attaches to the floor of the vessel and often attaches to the center console. T-Tops are placed on center console vessels and can have a canvas top, a flat fiberglass top, or a molded fiberglass top. T-Tops can include rod holders, cup holders, speakers, lighting, antennas, electronics boxes, or shade. In addition, you can add a Crows Nest, a second level tower, or simply add a ladder if you want to stand up on the top for better sight fishing.
