Catamaran means カタマラン in Japanese.
This putter was created by Hiroyuki Matsumoto, a famous Japanese putter craftsman. Seen from top to bottom, the push rod is H-shaped.
This putter borrows the stability principle of the original Pacific Islander Polynesian catamaran. The club head is very stable when swinging, so the number of revolutions of the ball is also very stable!
This is a very good putter, but it takes constant practice to hit the best shot!
