Nui was built in 1984 when they still built really strong and durable yet fast boats .The designer German Frers is famous for being able to design fast boats that perform well yet are can be of medium displacement . This Beneteau First 456 is such a boat and is remarkably similar to the Swan 48 and Grand Soleil 46 in hull profile . Nui is a very capable vessel that can take you on offshore passages safely and comfortably at high average speeds. She comes fitted with Solar panels and a watermaker so no need to carry a lot of water . The 45 cabin layout allows for nice privacy aboard great for families or guests. The seller is a marine engineer on super yachts and has fitted a nice reliable Volkswagen marinised diesel, capable of pushing her along nicely under power, driven by a bronze Max prop folding 3 blade . She also has a workshop with workbench and lots of spare parts and tools. She comes with a good set of sails with lots of life still in them. She carries a powerful rig capable of driving her nicely and her super hull design allows for good pointing upwind and fast reaching and running.’ The autopilot can handle self steering her well. So if you are looking for a good sized very strong and fast sailing vessel that can carry you cruising across oceans or even race competitively , this is for you , The seller sailed her easily with just his wife and two small children for many miles so she does not need a big crew to handle her.

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)
