Why Aluminum?

Aluminum effects the value of your boat and safety of your crew and mission.

An aluminum vessel has greater inherent value that is real.
Upfront costs for a fiberglass boat will almost always be cheaper than for a comparable aluminum craft.  But when the costs of routine maintenance--leaks, cracks, and problems stemming from structural fatigue in fiberglass--are factored in, aluminum becomes the clear choice.

Other Disadvantages of Fiberglass
Absorbs water.
Poor quality repairs are often masked by a shiny high-gloss finish.
Hard to adapt the boat, at any time in the future, to receive equipment that may not have existed at the time you ordered and configured your boat ...  hard to make configuration changes at all.
Hard to find a place to bolt equipment.

The USCG, the world's navies, workboat professionals, and motor yachts are some of those who choose aluminum for their vessels. 

Aluminum is a high strength-low weight material
Strength is important at sea, and aluminum delivers this strength.  It has roughly twice the tensile strength of fiberglass.  Under ideal conditions, flat dry laminated reinforced plastics provide wet tensile strengths of the order of 20,000 to 40,000 psi, average 30,000.  5086 marine aluminum, non-absorbent, has tensile strength of 47,000 psi.   Aluminum has the strength of steel with only one third its weight.  Aluminum's low weight requires less power to propel the vessel, resulting in lower fuel consumption.  Aluminum's light weight also allows for faster speeds, greater maneuverability, more horsepower, extra payload, and less draft.

Safety and dent resistance
Aluminum has a high resilience upon impact and will not likely splinter, puncture, or crack upon impact with an object but instead will dent.   And if the aluminum hull should need repair throughout the life of the vessel, traditional cut-and-welding methods are used that take advantage of the strength of the hull.  This also means less wait for you since repair time is dramatically decreased.

Aluminum's minimum temperature to melt is 1200 degrees.  It does not burn, blister, or rot.  These are obvious benefits over fiberglass and other plastic boats.

Resistant to corrosion
Marine aluminum will not rust.

Customer customization & uniformity of product
It is not expedient to mold a fiberglass hull into a customer's specific wants or job requirements, but with aluminum, customization is more viable.
