Doug fir pole mast
While still very keen on using aluminum for my gaff rigger's mast, I'm exploring the possibilities of using wood in case I can't find a suitable piece of tubing (strange as it seems, just the right piece of aluminum is proving difficult to find). If I have to go with just a doug fir pole, how important is it to have a clear piece? Are some knots acceptable? If so, how many and how big?
Thanks in advance,
Ben
