This Sovereign 18 is a beautiful boat and never fails to get compliments on her good looks. Link to her specifications sailboatdata.com/sailboat/sovereign-18.
She is easy to launch and retrieve and would make an excellent boat for beginners as well as experienced sailors.
Added mast raising system and trailer brakes. This upgrade included new wheels to replace the undersized wheels. New tires and new wiring.
Boat is extremely well maintained and in excellent condition. Has been bottom painted and interior liner shows no water leaks. New screens in the port hatches.
Equipment: Includes: Trailer ◦ Trailer brakes (new) ◦ Upgraded trailer wheels (new) ◦ New wiring ◦ Trailer extension (adds 3’) ◦ Tie down strap Honda 5 HP outboard with external gas tank Wind Vane Battery (new condition) Interior/exterior lights Compass Fire Extinguisher Built in sink (needs water container) Sails ◦ Main with cover ◦ Roller Furling Jib with sewn on cover ◦ New Screens for portal hatches Shade Canopy Dock lines, anchor Depth/fish finder Cushions (cabin and cockpit) 2 emergency floatation cushions Mast crutch for raising the mast Mast raising system (block & tackle, adjustable temporary side stays)
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 same or similar to the SOVEREIGN 17.
