Go to Sailing Texas classifieds for current sailboats for sale S2 7.9, 1985 sailboat for sale Kansas $7000
In1985 S2 paused production to modernize the resin that they used in their hull layup. This stopped the blistering problems that had plagued the boating industry for years.
The S2 7.9 line was paused at Hull #400. My boat is Hull #415 It has not blistered and has a professionally applied VC-17 bottom. Kevlar backstay and flicker batter (OEM parts included) New lowers. Loos gage included. New running rigging.sheets, Fully rigged for spinnaker with pole and three sails (one new).
Complete boat, trailer, ten sails +/-, life lines, ground tackle, etc.
All running rigging is about two years old. Near new 2018 Suzuki 4 Cycle / 6 Hp Outboard.
Boat is at Walnut Valley Sailing Club on Eldorado Lake North East of Wichita near Exit 76 of the Kansas Turnpike at Highway 77.
I can provide many more photos and would be glad to discuss any aspect of the boat with you.
I am selling it because I no longer need two boats.
SOLD
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)
A few (17) were delivered with a fixed keel and masthead rig. (See S2 7.9FK for specs.)
Inboard power available as an option… BMW 7.5 hp diesel.
