This tower is the best looking tower on the market, hands down. It's manufactured out of the best aviation-grade aluminium available AND is higher than other towers, giving you extra airtime and more space inside the boat. The 2 tubes connect to its horizontal bars, which run parallel to most window-lines, making the tower more rigid and stable. This tower fits on boats from 76 | 108 wide. The 1.3 model has improved mounting blocks (connection with the boat) for a stronger and more durable build.It fits boat decks from 76inch/ 193 cm to 108inch/ 274 cm in width and is made from an anodised aluminium, increasing corrosion resistance and surface hardness. The whole tower can be folded down for winter storage.
