Sharp Cal 30 with Dark Blue Hull and White Boot Stripe.! Has only been used in “FRESHWATER”.!
Stored inside, during the winter off-season, for the last 30 years..!
The seller favorites include her classic lines, and it’s very fast and very seaworthy.!
Powered by Yanmar 12 HP diesel inboard. The seller does not know the hours.
The hull deck has Awlgrip and bottom was painted in 2018. Sails are in great shape and the boat has spinnaker gear. The dodger is almost new..!
The Cal 30 is rigged for single-handed sailing..!
Purchase includes steel storage cradle.
Make sure to look through all the details, pictures and options that are listed below. If you have any questions, would like to schedule a personal viewing or make an offer, feel free to contact me anytime.!
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)
Alternate tall rig:
I: 37.0’
J: 12.0’
P: 32.0’
E: 14.3’
Replaced with another 30 footer, the CAL 2-30, in 1968.
