20229Alluminium mast wall thickness
- Mar 4, 2014I have a couple of options for sourcing an aluminium mast, but i don't know what kind of wall thickness i need.
I'm copying Johanna's rig (as much as i can).
I found a supplier who can sell me aluminium tubing that's:
- 4.2 metres long
- 20.3 cm diameter
- 3 mm wall thickness
Another fellow has a 12 metre aluminium flagpole he's willing to sell me that's:
- 12 metres long
- 25 cm diameter at base, 9 cm at top
- 6 mm wall thickness
I note that Annie Hill recently made her mast with a 6 metre section of aluminium tubing (don't know the diameter or wall thickness) and put a wooden topmast in, for both length and taper.
I might go that route too. Maybe.
But for now, can someone please tell me what the recommended wall thickness should be for an aluminium mast for an 8.5 metre (28 feet) boat?
