1978 MORGAN OUT ISLAND 41 - “INVINCIBLE” INVINCIBLE IS READY TO SAIL Grenada is a Great Place to start your sailing journey as it is beautifully situated to sail all the Caribbean Islands and is a safe place during Hurricane Season The OUT ISLAND 41, introduced in 1970, became legendary as a no-frills, center-cockpit standard, especially in the charter trade because of its outdoor and indoor living space. Invincible is the perfect example of an all-around coastal cruiser, Island cruiser or live aboard. The spacious deck provides plenty of room to move about while managing sails, and the well-appointed cockpit offers a comfortable vantage point to enjoy the journey. The interior offers ample room for relaxation and entertaining. Entering from the cockpit, you will enjoy a very large galley which is seamlessly connected to the main salon and cabins, creating an inviting atmosphere entertaining. To Port is a Settee with a large U-shaped Salon seating to Starboard. Forward is a large V-berth with connecting bathroom. The owners cabin is aft with built in cabinets for plenty of storage. The large windows flood the interior with natural light, enhancing the sense of space and connection to the sea. Current owner purchased her in 2012 out of Kamiah, Texas and set sail to explore the Caribbean with a young family of nine. Now, the kids have discovered their own path and its now time to discover new horizons. A custom fiberglass hardtop designed and installed in Panama. It holds two 360 watt solar panels. It has a water catchment system from down spouts. The front isinglass and canvas enclosures acts as a weather proof outdoor living area. The new Sunbrella cockpit cushions create a great space for napping, reading, dining and socializing.

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)
Dimensions for ketch rig.
