1st National Championships 2004
Seldén’s new Cumulus section, which was developed as
a lightweight (0.9kg/m) section specifically for non-trapeze
boats, is now available. This section combines light
weight with a ‘dynamic’ gust response for performance
through the range of conditions.
The rig was used to immediate success by David Wade
to win the 2004 National Champiosnhips, combining the
Cumulus/P&B rig package to best effect.
Seldén’s Olympus boom has the unique strength for weight
characteristics necessary to achieve absolute mainsheet
and kicker control.The redesigned 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.
