For sale a 1990 Ericson 38 (Pacific Seacraft) - Bruce King design in excellent shape (moving to a bigger boat).
Tons of new parts, including instruments (i70S), EV100 Autopilot, Garmin chartplotter, Standard Horizon VFH with AIS and RAM3 extension, transducer and much more. Sails in very good condition (one main plus one 125% furling genoa) It has a 200W solar system, diesel Hurricane heater, Raymarine radar, Universal M40 diesel engine in great shape - just serviced. Three water tanks, composting toilet… Bootom paint done in 2019. Ready to cruise around the world. Very capable blue water sloop.
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)
The ERICSON 38-200 shared the same hull, keel, rudder, with earlier versions (ERICSON 38x) but had a new deck and interior with a recessed companionway.
Shoal draft: 4.92’ / 1.50m
Wing keel: 5.00’ / 1.52m
