Rafiki 37 Cutter, 1977 “On Verra”(We’ll See) is a 1977 Rafiki 37 cutter. She is hull #16 of this famous blue water world cruiser designed by Stan Huntingford. Like many Rafikis, On Verra has been around the world. She’s done it twice, including a stop in Antarctica. That was with the previous owner couple, a salty pair that left maps and records of their 17 years voyaging aboard her. They continually maintained and refitted her, as have my wife and I for the 3 short years we’ve had the pleasure of owning her. We’ve only put a bit over 2000 miles on her, the longest crossing being the 800 miles from Dry Tortugas to Galveston. Kathy and I think this is the most secure-feeling boat we’ve ever sailed. And to say that after two six day Gulf crossings says a lot. She’s a really comfortable, sweet ride. Our life will keep us ashore a while, so On Verra needs another couple to take her around the world again.

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)
