‘Nautorious’ is the finest example of the Irwin 52 series afloat in the world today. She has been meticulously maintained and upgraded since she was acquired by her third and current owner in 1990.
In addition to her spacious, airy, and comfortable accommodations, she has first class mechanical and sailing systems in excellent condition which have been upgraded and designed for easy and safe shorthanded sailing.
In two major refits, in addition to continual improvements, the owner has invested over $450,000 in documented upgrades above and beyond the normal annual maintenance needed to keep ‘Nautorious’ in excellent condition.
Every system on ‘Nautorious’ has been replaced, upgraded, and or refinished to yield a yacht which is superior in all respects to the yacht when new.
‘Nautorious’ has a turn of speed which is surprisingly fast for a cruiser or a racer reflecting her Ted Irwin design pedigree. In short, ‘Nautorious’ is a joy to sail and cruise and is the ideal yacht for a couple or family interested in day sailing, racing, or long distance cruising and will not fail to please.
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)
A Mark II version was introduced in 1982.
The 52 was replaced by the 54 in 1988.
