The Perko Fig. 170 is a European style masthead navigation light in a black housing, certified for sail or power vessels under 20 m. It mounts on a vertical surface and comes with a 12 volt bulb. Visibility is given as 2 to 3 nautical miles.
Our take
The 65 ft (20 m) vessel limit is the first thing to check, because a larger boat needs a different masthead light. It also mounts on a vertical surface, so make sure the spot you have in mind has one before you drill.
From our buying guide
The lights a boat must show depend on its length and how it's being driven. A sailboat under power is a power-driven vessel and shows power-driven lights.
Check before you buy:
- The label gives its visibility in nautical miles, and that range meets the minimum for your boat's length.
- The maker rates it for boats of your length.
- A replacement LED is certified with the fixture it's going into, since the Coast Guard warns that replacement lighting may not meet the rules.
