54’ Grand Soleil 54 2009 | Panta Rhei

This is the brand new (2007-2018) Luca Brenta designed Grand Soleil 54′, launched at the Genoa Boat Show this October and immediately voted “Yacht of the Year”. The Grand Soleil 54′ incorporates all the luxuries that are common to a custom yacht, but engineered and developed as a production, and therefore affordable yacht. In harmony with the current Grand Soleil range, the integral galvanized steel frame provides the structural heart of the yacht. With below deck “Reckman” furling, all lines lead aft and below deck, a standard “german” mainsheet system, also below deck, integral transom garage, this yacht is brimming with the most up-to-date features. All deck hatches are flush, hull windows provide increased natural light to all cabins.

Grand Soleil 54’s performances

Upwind sail area to displacement  iThe ratio sail area to displacement is obtained by dividing the sail area by the boat’s displaced volume to the power two-thirds.

The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.

Upwind: under 18 the ratio indicates a cruise oriented sailboat with limited performances especially in light wind, while over 25 it indicates a fast sailboat. 263 ft²/T24.41 m²/T Displacement-length ratio (DLR)  iThe Displacement Length Ratio (DLR) is a figure that points out the boat’s weight compared to its waterline length. The DLR is obtained by dividing the boat’s displacement in tons by the cube of one one-hundredth of the waterline length (in feet).
The DLR can be used to compare the relative mass of different sailboats no matter what their length:

a DLR less than 180 is indicative of a really light sailboat (race boat made for planning), while a DLR greater than 300 is indicative of a heavy cruising sailboat. 138 Ballast ratio  iThe Ballast ratio is an indicator of stability; it is obtained by dividing the boat’s displacement by the mass of the ballast. Since the stability depends also of the hull shapes and the position of the center of gravity, only the boats with similar ballast arrangements and hull shapes should be compared.

The higher the ballast ratio is, the greater is the stability. 41 % Critical hull speed  iAs a ship moves in the water, it creates standing waves that oppose its movement. This effect increases dramatically the resistance when the boat reaches a speed-length ratio (speed-length ratio is the ratio between the speed in knots and the square root of the waterline length in feet) of about 1.2 (corresponding to a Froude Number of 0.35) . This very sharp rise in resistance, between speed-length ratio of 1.2 to 1.5, is insurmountable for heavy sailboats and so becomes an apparent barrier. This leads to the concept of “hull speed”.
The hull speed is obtained by multiplying the square root of the waterline length (in feet) by 1.34. 9.35 knots

Construction:

• At Cantiere del Pardo, maximum priority is given to the question of safety and structural strength.
• The galvanized steel grid, which is attached to the hull with a metal/acrylic chemical bond and further reinforced with a multiaxial cloth, provides stiffness and strength unheard of in laminated hull structures.
• The one piece grid structure is designed to uniformly distribute keel, mast and chain plate loads.
• This has the added advantage of lowering the C of G of the boat and also improving the stiffness of the hull thus providing the owner with superior sailing characteristics.
