Selling refit 1980 37 Hunter Cherubini. All new electronics, rigging, and sails since 2020. Located in South Amboy NJ. Boat is powered with the original inboard 30hp 3cylindar Yanmar & transmission, oil tested two years ago and was perfect. Engine and transmission oil changed twice a season. Never had any issues with the engine or any systems. Boat is ready to sail and brought us to Newport RI this year through some heavy weather without a hitch. All systems on the boat are in good condition and have been serviced and maintained regularly. New in the last four years: - All new standing and running rigging - New sails: o Doyle 135 Genoa o Precision Sails offshore fully battened main with 3 reefing points o Precision Sails staysail - New reefing system with new hardware and lines - Fully serviced winches - Raymarine linear drive autopilot - Garmin color GPS - Combination SeaTalk and NMEA 2k network - New Raymarine wind instruments - Additional Garmin GPS in cabin - Dometic fridge and dometic freezer (freezer is new as of 2022, fridge was purchased with the boat, still works great) - New VHF, antenna, and wiring done in 2022 - Mast rewired in 2022 - New masthead lights 2022 - New Garmin Radar 2022 - 3 New Lithium batteries purchased 2023 - 4 6amp AGM batteries purchased 2020 - New solar panels 2023 - New Victron charge controllers & - Composting head - Mostly-built hebridean wind vane (just needs to be set up and tested) along with wheel drive system. - New 2023 55lb Rocna Vulcan anchor - Included is a 4hp Mercury motor & 9 takacat dinghy (with wheels and other accessories). Dinghy has a dinghy anchor. - Rewired engine electronic harness 2022: all new marine-grade wires. - New Flexofold prop 2021 - New shaft, cutlass bearing, and dripless seal 2021 - New engine mounts 2021 Also included is plenty of spares for the engine and other systems around the boat. Boat has its price alone in electronics, sails, and rigging, and is a great value for someone looking to purchase a loved 37 sailboat.
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)
Shoal draft: 4’/1.2m
