41 derecktor sloop originally built in 1968 has one double V-berth in bow and 6 single berths. Built as a racer back in the day, not as fast as modern boats but still fast. New main, Genoa, stay sail, and canvas 2023 Spinnaker and storm sails included too New raymarine chart plotter and depth gauge 2024 Bottom painted 2024 J120 mast with rod rigging from early 2000s (2005 I think) 12 V fridge Lavac head Alcohol stove 200 watt solar system installed 2024 Many extras not listed
2011 Yanmar 3YM30 with about 500 hours serviced January with new impeller, belts, main shaft seal, exhaust elbow, fuel lines, coolant lines, fuel filters, coolant fill neck, stop solenoid, all new sensors, coolant temp gauge, and new overheat/low pressure alarm horn. Anything you see painted blue was pulled, sandblasted, and repainted too. Many many spare parts. Currently needs new injectors. Working to fix them, will update when fixed.
I also have a good 10 RIB dinghy with 8HP outboard for an extra $750

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)
