2000 Catalina MKII
SV Illusion is a proven and tested cruiser that we have daysailed, gunk holed and taken multiple trips to the Florida Keys and Dry Tortugas. Alas, my crew has grown up, we’ve gotten older and it’s time to move on.
What makes SV Illusion stand out is the inmast furling mainsail. While certainly convenient to quickly deploy and put away the sail, you really appreciate it when have to reef in high winds - never leaving the cockpit.
A 4.5’ Winged Keel is also blessing in the shallow waters of Florida. Illusion can go where most boats this size cannot and in Florida this is the max depth you should consider.
The below deck Raymarine Autopilot has the power to steer this boat is seas that the wheel pilots do not. It will drive straight as an arrow and we rarely actually drive the boat while cruising. It’s tied to the Raymarine Wind instrument so you can set it to follow the wind - a dream while cruising.
Equipment: New water heater and engine hoses, Custom sails for cruising, Universal 35HP Diesel, Raymarine GPS, chartplotter, depth sounder, Below deck Autopilot, dinghy davit, 40amp ProNautic changer. VHF radio, TV, Radio w/Bluetooth, updated speakers. Seward 2 burner stove with oven. It also has a 10’ Achilles Dinghy 2.5hp and 5hp outboard.
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)
Same hull and rig as the earlier version introduced in 1982 but with a larger cockpit and updated deck and interior. (Replaced with the CATALINA 375 in 2008)
Also available with a shallower draft wing keel and tall rig.
Wing keel draft: 4.52’/1.38m.
Dimensions for tall rig:
I: 46.75’/14.25m
J: 14.33’/4.37m
P: 41.0’/12.5m
E: 13.0’/3.96m
