Iroquois 30 MKII
Iroquois 30 MKII is a 29 ′ 11 ″ / 9.1 m catamaran sailboat designed by J.R. (Rod) Macalpine-Downie and built by Sailcraft Ltd. starting in 1968.
Rig and Sails
Auxilary power, accomodations, calculations.
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
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
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
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
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
Displacement / Length Ratio
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
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
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 Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
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)
The MKII is a development of the original IROQUOIS 30.

Launched 55 years ago, the Iroquois was certainly a revolutionary catamaran at the time. Reasonably fast and seaworthy, it inspired owners to take up racing or go blue water cruising. But is it still worth a look today?
The first version of the Iroquois, retrospectively christened the Mk 1, is certainly the most elegant and vintage. This polyester catamaran is undoubtedly the ancestor of our modern multihulls. The different elements - hulls, deck and underside of the nacelle - were all bolted together and then laminated. A simple construction method that doesn’t necessarily age all that well... The strong point of the Mk 1 is its compact rig, at the heart of which is a fully-battened mainsail. On the other hand, there is no trampoline. As early as 1968, the British boatbuilders Sail Craft Ltd. revised their product with the launch of the Mk 2: this catamaran was constructed by lamination; the freeboard and the bridgedeck clearance were increased, the coachroof was less prominent, and the hatches were improved. An aluminum beam was fitted between the bow of each hull, and this now held the forestay – a big very advance compared to the previous version - and offered a trampoline. The rig gained extra horsepower with an imposing genoa - up to 200% overlap - but the mainsail saw the loss of its roach. The daggerboards, simple sheet metal on the Mk 1 were thicker and profiled, now being made in plyw...
