Hunter 28.5 In good condition, perfect for day sailing and short cruises, very comfortable for its size, nice shallow draft for sailing on the St Johns River. Its currently slipped at Julington Creek Pier. Very affordable dockage with power and water. The boat has a Yanmar 2GM20F, fresh water cooled. Starts everytime. The engine has been cleaned the heat exchanger cleaned, all fluids changed and are clean, the boat was bottom painted two year ago and is in good shape. The sails are average with a few good years left. It has radar, self steering, pressurized water, 12Volt TV with antenna, good reception in town. No leaks, motor mount on the transom for a outboard motor. All cabin lights have LED bulbs, great storage space, lots of extra parts for the engine including a 168.00 dollar exhaust elbow. Some specialty tools available for engine mounts, new air filter.
Equipment: Usual equipment for a boat of this size. anchor with anchor chain mounted TV 14 gallon water tank 11 gallon diesel tank 2 batteries start and deep cycle with two circuit battery switch (Sea Systems) battery charger (West Marine) new fixed ports, lexan all opening hatches and ports got new seals and were rebedded with 3M 4200 or 3000. bimini and dodger with connecting piece boat hook cushions are clean and in good condition alcohol stove AC system, 3 outlets Locking marine grade extension cord 200ibs lift system transom mounted that swings, great for loading heavy items from the dock to the boat
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/wing keel: 4’/1.21m
