Very nice CAL 27. This sailboat is perfect for the Bay area, she is light, stable and can take a good breeze. If you are looking for a basic easy sailing boat, she is the one!!
With a nice ample wide beam of 9 feet, what first impresses is the space in the cockpit and the space down below. It feels open and airy due to the side windows and the updated portholes through out. Comfortable seating on both sides of the cabin, and nice storage from stem to stern. As you walk below, the aft cabin is a chart table work area, with a very large icebox. All electrical primarily 12V switches are on the aft bulkhead.
Moving forward in the cabin you reach the midship bulkhead and just ahead you have a porta-potty and cold water sink and a good size V-berth.
This CAL 27 points well and sails like a dream, the owner confirms.
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)
The second in a series of 3 different CAL 27’s, all designed by Lapworth. A Farymann diesel was offered on later models. A boat of the same design called the CROWN 28 was built in Canada.
