The Flow 19 is a racer cruiser modeled after Beneteau First 18 and 24 sailboats. It has a much roomier and comfortable cabin than the 18 with ample storage and is considerably lighter, easier to rig and tow than a First 24. Custom built in France by a shipyard specializing in performance boats and composite structures, she is a fast and lightweight 19-footer, perfect for coastal cruising and day sailing. The 154lbs fully retractable swing keel paired with 2 x 132 lbs water ballasts provide a comfortable weight/ballast ratio. The hull and deck are built using wood/epoxy construction and rigid foam in the hull provides positive flotation. Critical parts such as rudders, swing keel and coach roof are molded infused composites. Exterior surfaces are covered with a durable layer of glass cloth and the hull gets an extra layer of protection. The absence of exposed wood minimizes maintenance and guarantees long lasting performance. The roomy cabin has 51 inches of headroom for comfortable seating and can accommodate up to four. At less than 1,000 lbs, the boat can be easily towed by a small car and thanks to her fully retractable keel , she can be launched from shallow ramps and beached anywhere. With the keel up and her flat bottom, she easily slips on a boat lift at your dock. The 3HP ePropulsion electric outboard, allows the boat to be also used as a silent and eco-friendly cabin cruiser to explore rivers and small lakes.

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)
in 2018 Beneteau purchased a controlling stake in the Slovenian builder Seascape, bringing all Seascape models into the fold of its First range.
