2009 Landing School LS 30 Landing School boats are renowned for their craftsmanship, durability, and performance. The meticulous building process, combining traditional techniques with modern innovations, ensures that each vessel is a testament to the skill and dedication of the builders. A 2009 Landing School 30ft sailboat, crafted through this rigorous process, is a prized possession for any sailing enthusiast.
This high performance custom build launched in 2009 has successfully bridged the gap between efficient day sailor, and competitive club racer.
A Selden carbon fiber rig supports up to 506 sq/ft of sail including a fully battened square top mainsail, and an asymmetrical spinnaker.
Sale includes custom dual axle trailer.
Boat is equipped with inboard diesel engine Nanny 10HP
Fast, fun boat in great condition! 90 FS PHRF rating makes her quite competitive, usually finishing just behind the Beneteau 36.7s and many times beating them in adjusted time. Easy to sail shorthanded and crewed.
Recent upgrades include:
Jib 2023 Mainsail 2024 Spinnaker 2024
The bottom paint 2024.
Interior cabin and cockpit paint 2024
Raspberry Pi open charter plotter 2023
Solar panel
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)
