I am so glad that my formula sailing is "quite technical, requires high ability and high strength".
I am reasonably skilled, but I am 66 years old, and weigh 78kg. While I don't push my big rigs (11.0 & 9.2) to the limits of most formula sailors, I nevertheless have great fun planing fast in winds where only the long boards are cruising around. I rarely drop the sails, but I do have "easy up-hauls" on my three largest sails so I don't waste my strength up-hauling if the need arises.
Formula isn't that tough, but it can be pretty darn exciting running down wind with a big sail in 15 to 20 knots.
