Sonata Tuning Information

Update

The Seldén Sonata mast is indisputably both sailors’ and sailmakers’ first choice. The latest Seldén Sonata specification has been further refined utilising the input of top Sonata sailor and sailmaker Steve Goacher.

A combination of the expected Seldén quality and consistency, plus attention to detail on specialist fittings, combines top performance with ease of use.

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.
