Aluminium masts replacing wooden

[Cooper Dan]

Hi All.

Advice needed.

Have just rebuilt my back wooden mast, bottom 2.4 meters was rotten, it's a long story and i will post the rebuild images online and description soon. The results are great !

Have just got to the stage were I am about to put the finishing coats on when I find that there are many 20 meter lengths of 200mmOD, 10mm wall aluminum extruded pipe lying a few hundred meters away that the marina management would like to get rid of.

Questions I have are:

My masts are a heavy meranti, and reasonably stiff.
Would I need to stiffen up the aluminum masts?

Does anyone have the Wharram mast size chart and can tell me whether 200mm ond 10 mm walls are suitable for a 15m mast.

Any past negative experience with aluminium masts?

 

Regards

Hi Copper Dan,

Here is what you are looking for ,from the man JW himself. http://wharram.com/plansupdate.htm. Hope the link works, its taken from the plan update section of the Wharram website. It says for Tiki 46, if using aluminium, diameter 194mm (same as timber), wall thickness 5-6mm in alloy (timber is 32mm). Am sure this will help.
Cheers Trevor McKenzie
