VERSATILE ABS HULL
Velcro straps are fussy
Wild graphics might not
suit conservative tastes
;e M41’s ABS hull is a monster at 40 inches long,
and the catamaran design isn’t picky about running
conditions. If the wind kicks up some chop, the tall twin
hulls (sponsons) keep plenty of plastic in the water to
maintain stability. In smoother conditions that allows higher speeds, air trapped
beneath the broad flat area that bridges the sponsons helps lift the hull out
of the water. Battery position helps tune how the hull rides, and there’s ample
space inside the hull to move the Velcro-secured packs fore and aft. ;e hull’s
interior is supported by an intricate molded-plastic sti;ening structure that
incorporates a beefy transom bulkhead. Stainless-steel hardware secures the
waterproof electronics and receiver box, which are fitted to a removable tray.
Disengage the servo linkage, unplug the speed control’s water-cooling hoses
and wires, loosen two screws, and the entire electronics tray is in your hand—
;ere’s plenty of blue-anodized action at the business end
of the M41. ;e rudder, rudder support, and strut begin life
as 6000-series aluminum extrusions before final machining, and stainless
fasteners secure the parts. ;e rudder incorporates the pickup for cooling
water, and pivots on bronze bushings for slop-free action. Rudder angle, prop
height, and strut angle are adjustable, with a pair of stainless trim tabs allowing
further tuning of the hull’s attitude on the water. To help with precise drive-strut
adjustment, an alignment tool is included, which makes it easy to set the strut
height ( 6 or 7mm) and angle (0, 1, or 2 degrees).

takes a minute to remove the electronics tray. Stainless-steel hard ware is used throughout.
Right: All the hard ware
is aluminum, and you
can set strut height and
trim tabs are factory
installed. Below: A flex

keep the shaft lubed.
