The MacGregor 65-1 was originally designed specifically for the Trans Pacific Race (Transpac). The boat is powered by a Pathfinder In Line 6 Cylinder, 85 HP diesel engine with dedicated fire protection in the engine compartment, and another fire extinguisher in the salon area.
The vessel is equipped with a GPS chart-plotter at the nav station with a repeater at the helm, VHF radio with AIS receiving and a remote mic at the helm, a RayMarine RL80C color radar station, and radar repeater.
The port and starboard mid-ship and forward berths, a large V-berth with an after-market hatch above, and a double aft berth allow 8 to sleep comfortably onboard. The single head has a toilet with push-button macerator, a sink, and a shower with a tub.
There is a main 12V panel, 2 auxiliary 12V panels, a battery switch, and battery charger.
The galley features a 3-burner gimbal stove with oven, a sink, and a small refrigerator/freezer (needs compressor).
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64)2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
This, the first, more racing/performance oriented version of the MACGREGOR 65 sold well considering it’s size. The later, pilot house version, was even more popular, with over 70 sold.
