Great Sailboat! Very Spacious for a 30 foot! Overall the boat is in good shape. She’s a little faded and needs some paint. She has a couple leaky windows. Needs masthead bulb replaced (I have bulb.) Had to take engine out to replace pan gasket, so I went ahead and had the engine completely overhauled. Had all valves cleaned, valve springs replaced, replaced belts, new hardware, new engine mounts, new spark plugs, had the motor-head cleaned and machined to spec. The engine bay and engine been cleaned and have fresh paint. Brand new pump for the manual marine toilet in the head and brand new submersible bilge pump. All seating cushions have been reupholstered with marine fabric. The rest of the quarter birth cushions are also in excellent condition. V-birth cushion is in fair to good condition. Has Catalina designed sleeping support springs for the forward V berth and is comfortable. Has shower in head. Spinnaker and Jib have been kept in climate controlled storage and are in great shape. Main sheet has been stowed in canvas cover. Has a very well organized electric panel at the chart table. All interior light works, but still has those cool old school oil lamps with fresh wicks. Interior teak is in good condition. Has a working water heater, and has two water storage tanks. She has lots of space for storage. She also has a minifridge, but could fit a larger one if desired.
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 √LWLA 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)
