The batteries pictured are Rolls S6 250 flooded cells, nominally 281 a/hr. They came with the boat and are of unknown age but currently seem to work OK. They are not the cell I would pick as they are a lightweight battery. The clue is that the spec sheet gives a CCA number. True deep cycle cells don't have that. The taller L16-EX is rated at three times the cycle life, about 3,750 cycles to 50% DoD compared to these at 2,000. You really do need to look at the full spec to know what you are getting! In Canada these are currently around $320 com-pared to the L16 at $590. The black battery is the starter battery which is a simple H/D car battery that starts the engine and supplies the windlass.

Special Report: How to Prevent AIS and VHF Antenna Malfunction

Safety of Life at Sea (SOLAS) ships-including tankers, passenger vessels and cargo ships over 300 gross tonnage-must be equipped with Automatic Identification Systems (AIS). In the U.S., carriage requirements also includes vessels over 65-feet. AIS can allow you to see a distant ship, but is not a substitute for radar.

Owners report that in winds of from seven to 12 knots, the boat is practically unbeatable in club racing. The typical PHRF rating of 135 for the deep keel boat is faster than most other cruiser/racers of her size.
