The Ultimate Solo Mast
During 1999 Jim Hunt asked Seldén for a section stiffer
than our ‘C’ section up to the hounds, but flexible
fore and aft and stiff sideways in the topmast.The objective
was to control sail shape through the wind range with
kicker tension, but ensure that the mast stays straight
sideways for downwind and medium wind speed.
The Seldén Cumulus Solo mast achieves these features
through the special double topmast taper, which gives
minimum fore/aft size without compromising sideways
stiffness.
The Cumulus mast is ideally suited to sailors 77kg and
above and has won every National and World Championships
since its design.
The C-sleeved mast, pioneered by Ken Falcon, is still
the definitive Solo mast for the sailors 77kg and less.
NEW Boom Section
The Seldén 2628 Boom has unique strength for weight
characteristics necessary to achieve absolute mainsheet
and kicker control. Boom slides allow direct attachment
of mainsheet blocks for efficient boom 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.
