Magnum Marine

What Magnum Marine does

Magnum Marine is a privately held, family-controlled luxury offshore powerboat manufacturer founded in 1966 by Don Aronow on Miami's Thunderboat Row and currently headquartered in Aventura, Florida (2900 Northeast 188 Street). The company, now led by CEO Katrin Theodoli (second-generation family stewardship), operates at a small scale of 11-50 employees and produces high-performance deep-vee hull vessels (24-degree deadrise) for two distinct end markets: high-net-worth individuals seeking luxury offshore pleasure craft, and government/defense agencies requiring patrol and rescue vessels.

The company's product portfolio spans the Magnum 70 and flagship Magnum 80, the recently introduced Magnum Bestia 50 and Custom 70' Express, a Classics series (Magnum 25', 27', 28', 35', 38'/40, 45, 50, 53, and the Pininfarina-designed 63), and dedicated Patrol Craft. Construction uses hand-laid, infused, and vacuum-bagged composites of carbon fiber, Kevlar, and high-strength epoxy/vinyl-ester resins, with lamination schedules approved by both RINA and Lloyds testing laboratories. Magnum was an early adopter of surface propeller technology (claimed 20% fuel-efficiency advantage) and uses battery power for docking and maneuvering.

Revenue is generated primarily through direct new-boat sales via the Aventura showroom-and-shipyard, a global brokerage operation for pre-owned Magnum vessels, and a small e-commerce boutique for branded merchandise and commemorative publications. Pricing for vessels is not publicly disclosed and is quote-based; visible brokerage listings for recent builds cluster in the high six-figure range. Distribution historically extends through a long-standing European dealership partnership (the Theodoli family), with operating geographies spanning the United States, Greece, Italy, and historically Kuwait, complemented by an annual owner reunion program in Miami, Antiparos, and Porto Rotondo.
