Ritchie · B-51W · B-Series

Your course, without a margin for error.

51 mm direct-reading dial. DirectiveForce magnets that lock onto your heading instantly. A bracket that adjusts by hand. The B-51W is the compass you install in minutes and forget about — because it never fails.

Ritchie equipment installed on a passenger catamaran — real navigation in real conditions.

Precision

Read your course, don't interpret it.

51 mm dial with high-contrast numbers. Direct reading eliminates ambiguity: you see the exact degree without calculating, without guessing. DirectiveForce magnets lock onto the heading in fractions of a second — no oscillation, no doubt.

Night

3 a.m. The dial, lit up.

Internal green illumination doesn't depend on batteries or the console. It is passive, constant, and always ready. When everything else goes dark, the B-51W is still there.

Installation

Bracket, thumbscrews, done.

No drilling, no sealant, no waiting for anything to cure. The bracket mounts in minutes and adjusts by hand. The thumbscrews allow you to reorient the compass without tools. Built-in compensators to calibrate magnetic deviation on-site.
