Well loved Catalina 30 for sale. Not a project boat - the long term upgrades have been completed. Hull has epoxy barrier coat. The atomic 4 engine is rebuilt and runs like a champ.
Were moving up to a bigger boat, so this is priced to sell.
Equipment: Wood trim is freshly varnished. 2020 new exhaust water muffler. New exhaust to stern with new thru hull. 2021 new sanitation hose. No stinky cabin! New water pump. 2022 new running rigging. 2022 new winter cover. 2023 new Raymarine autopilot. 2023 Newly machined prop shaft, new cutlass bearing. Rudder bushings replaced. 2024 new 150% Genoa, Raymarine i70 multifunction display, Airmar triducer, B&G anemometer. Well stocked: dishes, tools, Magna grill. Fresh flares, and fire extinguishers. VHF with remote RAM mic. LED lighting. Whisker pole, Spinnaker with ATN tacker and sock.
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)
BMW diesel (9hp) offered as an option.
