GP 14 Tuning Information

NEW Mast Section

Working closely with the Class Association and Speed Sails, Seldén have upgraded the registered GP14 section to our new Cumulus section. The rig has proven to be the best available winning the 2006 World Championship and taking the top two spots at the 2007 National Championship. The Cumulus section has been supplied as standard on all new Speed Sails boats since 2004.

A more modern section than the ’D’, the stiffness to weight ratio is more efficient, and with an improved taper, the Cumulus creates a faster, more user friendly mast for the boat.

"The Cumulus mast is very responsive to changes in controls and rig settings, making it easy to get the maximum performance out of the rig across the full range of conditions. The fittings are well engineered for functionality and reliability." Ian Dobson, World Champion 2006 & 2008.

With a similar fore and aft stiffness to the ’D’ section, existing mainsails will set well on the mast with the improvements coming from the more DYNAMIC nature of the tube.

Boom

The Seldén 2628 boom has the unique strength-for-weight characteristics necessary to achieve absolute mainsheet and kicker control, and our boom slides allow direct attachment of kicker and mainsheet blocks for efficient centrelining.

Why Seldén?

Choose a Seldén mast and you will find many performance enhancing features unique to our products, for example:

• The Seldén tapering system ensures that our tapers are minimum size and weight. This gives low windage, centre of gravity and topmast weight. This maximises your speed by enabling the topmast to react quickly to gusts and waves giving better acceleration, a smoother ride upwind and, ultimately, more races won!
• Automated welding keeps excess heat out of the taper for guaranteed consistency and performance. The weld produced is so perfect that there is no need to mechanically grind the weld (which can induce inconsistencies). This means that once we have finalised a winning design, you can be sure that your spar will perform identically to the champions.
• All masts are heat treated in our purpose-designed oven. This artificial hardening ensures that you get maximum performance from the high performance aluminium alloy.
• Our spars pass through a purpose-developed bead-peening machine. This gives the mast a perfect satin finish that dramatically improves fatigue properties, giving you a mast that will perform reliably for many years.
• Top quality fittings such as our fully adjustable spreader bracket and highly durable cast gooseneck ensure speed and reliability on the racecourse.
