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.

Beneteau First 345 Used Boat Review

The Beneteau First 345 was designed as a moderate displacement racer/cruiser, and much of its popularity has been because of its success in blending the two functions. In fact, it could be said that the First is a racing boat that contains a cruising interior. The architect is Jean Berret, a Frenchman noted for his cruising and racing designs (he designed the 1985 Admiral's Cup winner, Phoenix, a Beneteau one-tonner).
