These are direct replacements for lights used on all early Catalina 25's, Catalina 27's and Catalina 30's. The housing is stainless steel rather than the original die cast zinc (yes they were the same metal as your sacrificial zinc anodes!)
Sold as a pair (port and starboard)
They are a very convenient replacement but we suggest you consider moving the bow navigation light to your pulpit. When the boat is heeled going to weather, hull mounted lights make a pretty reflection off the bow wave, but they are invisible to another boat to leeward.
Distance: 1 NM
US Coast Guard Approved: Yes (only for replacement of existing lights, not for new construction).
