Laser, Control systems, Vang block with “V” cleat – “Classic”
This was the lower vang (or “kicking strap”) block originally supplied with all Lasers & latter only with the Laser “Classics”.
It you are using a Laser for “cruising” the “Classic” set-up is fine. it is cheap & does an adiquate job resulting in a fairly forgiving boat to sail & plenty of room under the boom.
If you are using a Laser for racing then you will need the XD version. The XD version is much more powerful which if employed correctly results in more speed but a less forgiving boat & less room under the boom.
