Our definition of a ”keelboat” is a boat sized in between a dinghy and a yacht, with a length of approximately 18-28’. These boats often have a 50% ballast ratio. Consequently, the weight of the keel represents half of the total displacement.

From the very beginning in the 1960’s, Seldén produced a comprehensive range of aluminium yacht masts. Since then, the range has developed and expanded. The seven new keelboat sections feature a wealth of sophisticated and functional solutions, originating from the dinghy range and the yacht range.

The sections are extruded and anodized and they are all available with a tapered top. When tapering the mast section, a wedge shaped piece of the section is cut out and the section is squeezed together and welded. This process does not affect the strength of the mast section as it takes place prior to the hardening process of the section. The taper is parabolic which means it has a fair curve over its entire length. A tapered top results in lower weight aloft, with less windage and improved response to gusts.

There is a wealth of useful information in the Selden Keelboat Data Sheet which you might find useful. Let us design your keelboat rig or ask us about our One-design solutions.
