For durability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

The Prism is a stripped down racing compass. The Prism provides unprecedented accuracy, coupled with a massive display, in a compact package. At a mere 137 g (4.8 oz) it is the world's lightest racing compass. The Prism uses only magnetic input as its heading reference, has no memory, no user inputs, and performs no arithmetic functions. It's legal in all classes that allow electronic compasses.
