1982 S2 Yachts 7.9 Grand Slam trailerable sailboat
Begin your sailing adventures today, everything to enjoy your time is included. Awaiting you at the Gulfport Marina this sailboat has had the diesel engine and fuel tank removed to allow for additional storage space underneath the cockpit and replaced with a new 2021 Mercury 5hp Sail Power Propane outboard with 25in shaft drive and sips on two 11 lbs tanks. There is a small air conditioner that keeps the interior very comfortable on those humid days on the coast and a rarely used porta potty. Due to the size and the Raymarine tiller autopilot, motoring and sailing this boat solo is a breeze. As an added benefit and peace of mind during hurricane season or when a mandatory evacuation is issued by the Gulfport Marina or looking to sail new waters, you can load the sailboat on its custom tandem axle aluminum trailer with new rims, new tires and new stainless-steel hardware and drive away.
Length 26 ft / Beam 9 ft / Draft 1 5 ft (retractable daggerboard)
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.
