Magnum Marine boat / yacht – yesterday and tomorrow

A famous ad for Magnum Marine once they moved up to building yachts

Don Aronow started Magnum Marine around 1966 after he sold Donzi Marine on 188th Street in Miami, FL (Thunderboat Row), which he had brought to market after he sold Formula Marine in 1964. Later, Don Aronow also started Cary Marine, Cigarette Racing Team, SquadronXII, and USA Racing Team. He also designed the first Apache powerboat. Finally he ran some experimental outboard powered racing boats, a Cat or two, an unconventional Unlimited  Racer, etc.   

Get a copy of Michael Aronow’s book (ISBN 0-945903-22-7) to really follow Don Aronow’s life and boat racing / boat building career. Its now a rare book, but a copy surfaces once in a while.

Chris Brown / seabuddy got as far as taking a sea trial in a 27’ Magnum twin small block Mercruiser with Alpha Mercruiser sterndrives before he came to the conclusion that it just was not a fast enough boat for him (she did top speeds in the mid 50 mph range). 

Now Magnum Marine is working on their biggest yacht yet. In 2012 Magnum Marine expects to have their trend setting 100’ yacht ready. That yacht is expected to run three engines totaling 7,800 in Hp through three Arneson Surface Drives reach light load speeds in the low 60 mph range. Magnum Marine and Arneson Surface Drives have made many boat and yacht marriages together. I have sea trialed that combo and its works exceptionally well. Currently, Magnum Marine gives out specs of LOA 95’, beam 20’ and a weight of 147,000 lbs for the 2012 Magnum Marine 100’.

Today and the past of Magnum Marine

Filippo Theodoli,  some time ago, gave seabuddy a incredibility smooth, high speed test run / sea trial in a Magnum 45′ (the1980 Hull design) while he (and I) were attending a SNAME (The Society of Naval Architects and Marine Engineers) meeting near the Miami Seaquarium In  Key Biscayne, FL to demonstrate the extra speed and excellent handling of an Arneson Surface drive in a heavy, luxurious deep vee offshore pleasure boat. (Being in boating for about 55 years and messing around within the various aspects of the marine trades for about 30 of those years makes for an interesting boating life and lots of stories)

His skill behind the wheel and in knowing the high speed, shallow water capability of that type of drive was impressive.

His boat was also amazing (as well as that drive) that day.

Arneson still makes that drive and seabuddy believes that one can see a clear path from an old standard inboard shaft drive, to the Arneson Surface Drives, to the Volvo IPS (with a lot of WW II torpedo prop knowledge thrown in).
