SLIDING RIGGER in 1982 (experimental works)
Usually, racing boat has a sliding seat and fixed stretcher and riggers. But the sliding rigger boat has fixed seat and sliding stretcher and riggers unit. This mechanism reduces the mass movement of rowers. So, the boat can run faster with less pitching and surging motion. The sliding rigger mechanism is not so new as idea, but the heaviness of the materials to get the strength of sliding unit (and also hull) has prevented the realization. But the progress of materials; for example of carbon fiber, enable to release this mechanism. In 1981, sliding seat 1X won at the World Championships. In 1982, when I got a picture of sliding rigger scull, I was shocked. "This is a revolution! In a few years, most boats will change to sliding riggers." So I tried to build a sliding rigger scull for the experiment to feel this new mechanism. Unfortunately, sliding rigger is not so popular. And the race rules forbad this mechanism. Because, the regatta is the competition for the human performance, not for the boat design or economical power. It is one of the reasonable opinion. But I also hope, this excellent mechanism will revive as one category of race, someday.
