Booms
Aluminium tube supplied in 400mm lengths suitable as booms for the IOM (International One Metre) class.
The recent trend in the IOM class is to use a lighter boom for the top rig and normal 11mm mast material for No2 and No3 rigs.
While we continue to see the 10.1mm Arrowshaft used as a lightweight boom we are now seeing many people switching to the thicker walled 10mm section in the IOM class as the tube is stiffer and less subject to corrosion.
Cat Components supply the 11mm and 10mm material.
