For interest see this Article from 1984 May - June Freesail issue on "Choosing the Right Mast". I had the Windsurfer flexible "fishing rod" blue mast 1982, then the Gaastra Blue glass mast 1983 (snapped it about a year and a half later) then went in about 1985 to the Kilwell 4.50 recreational surf mast made in New Zealand. Things have changed , technology, quality, reliability, materials, durability and design has improved and masts cost a lot more today. Also we no longer have one piece masts which was the only choice in 1984, now 2 piece is the standard. Aluminium masts no longer exist. No longer do we have local mast manufacturers in Australia except for specialised companies like Slake.
