This 2006 J Boats J109 is quick and responsive yet stable and is what sailing is all about. With its sailing-friendly deck layout and cockpit, the J/109 is as easy to manage offshore as she is entertaining dinner guests on the mooring.
The J/109 saloon features an L-shaped galley, with a stainless sink, large icebox, and gimbaled propane stove/oven. Two full-length settee berths and a drop-leaf varnished table providing seating for up to six people.
The large, forward-facing navigation station has convenient table-top and cabinet storage and easy-access hinge-down panels for a suite of electronics. Two double cabin (1 port, 1 forward) and one toilet with shower and marine head.
Throughout its history, the J/109 has logged race wins in some of the world’s most prestigious events - including the Rolex Fastnet Race, Newport-Bermuda Race, Chicago-Mac Race, and the Rolex Caribbean 600 she can be easily sailed by a cruising couple or a family crew.
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 version: 5.75’/1.75m.
Volvo D1-30 diesel offered later.
