Ritchie's Helmsman Series is a premium compass line with a large 3 3/4" dial.
It is engineered to fit today's most popular size boats.

This Helmsman flush mount style compass provides a secure, low-profile installation, excellent dial visibility, and minimizes the effects of hull or engine vibration.
On powerboats, it is used on fishing towers, fly bridges, center consoles and bridge decks.
On sailboats, it is most often mounted on side decks, coach roofs, or steering pedestals.

The traditional flat card style dial in the HF-742 is best suited when mounting the compass in a location where you are looking down at the compass to see the course heading.
On their flat card dials, Ritchie adds a special lightweight PowerDamp baffle that eliminates spinning and dial jumping at high speeds and in rough conditions.

Note if you are replacing an older HF72 or HF73 Helmsman (which had a 5" mounting hole) with one of these newer models, you will need to purchase an H-A adapter plate to compensate for the smaller 4" hole size of the new HF742/743 compasses. See Related Products, below.
