Dinghies are any boat with a movable fin underneath which provides lateral resistance and limited stability. They tend to be more maneuverable because they are lighter and allow sailors to get going quickly. CBI owns twelve Lasers — one of the most popular boats in the world — for sailing single-handed. We also own 18 420s built by Zim sailing for double-handed fun. We use both for Race Team practices and both are among our most popular boats for advanced sailors. Our Mercuries are also dinghies, although they are not lightweight like our 420s or Lasers. They still provide the responsiveness and feedback that make dinghies such great teaching tools.
