es, Bernd causes high costs in this period, making it in composite (oval shape) with carbon fiber and epoxy resins cost over 20,000 euros.
? As you know, I have an aluminum tube supplier and we opted for 6mt aluminum tubes, 2 tubes of 100mm diameter x 5mm thickness, 4 tubes of 80mm diameter x 5mm thickness and 1 tube of 60mm diameter x 5mm thickness.
The two 100mm start from the base, two 80mm with one meter joint always 80mm and the crosspieces the first 80mm and the two at the top 60mm, the mast head with pulleys and brackets as per drawing.
The aluminum mast has a cost of 4,500 euros, a good savings in composite, it would have been nicer with the boomerang-shaped crosspieces but.

I had a bad time with my hand after so many years that I hadn't had an accident, I could have lost three fingers on my left hand.
I was cutting a piece of mahogany for reinforcement under the base deck of the mast, the blade of the band saw broke, when it came out of the flywheels it caught my three fingers. early february 35 days to heal and it just grazed me........
Now I'm going like a train again :-))
