NEW Section for 2004Seldén (formerly Proctor) spars have been used to win more Osprey Championships than any other manufacturer’s products.
In 2004, we now offer two mast section options, the well proven Seldén Epsilon section, specifically designed for trapeze boats with a long unsupported topmast, for a ’standard Opsrey. This mast section has won more Osprey Championships than any other mast.
For the HPS spec rig with the narrower chain plate position, we recommend our Gamma section. Developed with Andy Barker, this will give more ’tube’ support, with a extremely DYNAMIC tip to create a user friendly, fast tip.
Boom Section
Our 2633 section offers the most efficient stiffness to weight ratio boom, supplied with a light weight cut-away at the outboard end.
Results
Epsilon section has won more Osprey Championships than any other section.
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.
