Sparcraft FM Mast Sections


Sparcraft FM Mast Sections are a series of modern, dimensionally-efficient Mast Sections, similar in design and concept. Suitable for both Racing and Cruising vessels, Sparcraft FM Sections comprise a range of Masts suitable for boats from 16' to 80' (5M to 25M). FM Sections are sometimes designated as S Sections, there is no difference.

Though Sparcraft uses a number of common components in their Spar Assemblies, many Mast Parts are specific to a particular Mast Section. For these parts you must determine which Mast Section you have by measuring its' maximum Outside Dimensions.

Click on individual Mast Sections, below, to see all hardware used with those Sections.

For common replacement Mast Parts, See Sparcraft Mast Components, below.
For complete Mast Assemblies, contact us with details.
