Atlantic Towers believes that aluminum is the “hands down” choice for boat towers of every type. For a given weight, correctly designed aluminum towers can be made much stiffer and stronger. Stainless steel weighs nearly 3 times as much as aluminum. Stainless steel makes great springs, not a desirable characteristic in boat towers. High end Boat Builders such as Viking, Bertram, Cabo, Hatteras and others equip their boats exclusively with aluminum railings, ladders, hardtop structures and towers because it is the best material choice.
