in particular) are way down on current prices, glass and epoxy has not changed
much in the last few years. It should be noted that the price for the
Visionarry mast below is also out of date due to recent increases in carbon
costs. The carbon shortage is expected to continue until at least the end
of the year, which is what they were saying last year. Expect prices to
plummet if/when Chinese carbon plants start operating.
A Harry mast is about half the weight so as a ball
park number you could assume half the cost. Painting will be about the
