Hulls are hand laminated, and vacuum bagged, using either GRP, bullet proof Kevlar or carbon fibers for greater strength and weight reduction. Bottoms are solid glass of generally more than 2" thickness.
Hull sides, deck and bulkheads are of composite structures; fiberglass/ epoxy and foam core for greater strength and weight saving.
Aircraft type nomex composites are used for light weight interior structures.
Arneson surface drives improve top speed whilst reducing drag and improving fuel economy.
****Most important systems have a back-up system to prevent potential problems. Here the back-up steering system.
Pumps for equipment in the living quarters, as for the heads, icemakers, refrigerators etc. are often engine room mounted to keep the living areas quiet.
****Special insulation of the engine room, bulkheads and cabins provides extreme sound dampening for a more comfortable ride.
The deep-vee hull design with 24 degrees deadrise guaranties a comfortable ride even in adverse sea conditions.
Custom designed stainless steel Rolla propellers provide improved performance with less vibration
Magnum hulls are thick, safe and heavy. Mass is a key factor in Magnum’s comfortable ride. " The boat’s construction isn’t super exotic, just super strong."
