systems approach taken at Caliber than the
sea chest in the engine room. The concept is to reduce the number of
seacocks below the waterline from 10 to one. All water intake for the
entire boat comes through one reinforced box that has its top above the
boat's loaded waterline. The box has a Plexiglas inspection port fitted
with massive wing nuts so the inside can be cleaned of weeds or debris
while underway. Cooling water for the engine and generator, saltwater
for the heads and saltwater taps in the galley all flow from the single
sea chest. The whole system can be shut off quickly with a single
mechanical closure. Reducing the number of holes in the boat reduces the
risk of a failed seacock and trouble by a factor of 10. That is good
The engine room that houses the sea chest lies under the cockpit. Access is via two large doors on the port side and via smaller doors in the aft shower stall. The engine is mounted quite low in the boat and is fitted with an Aqua Drive unit that reduces vibration, wear and noise. The battery bank has been installed on a platform above the engine. Fuel and water filters and all battery switches can be accessed directly via the galley side doors. Caliber takes the trouble to label everything in the engine room and even posts useful reminders of how gear and equipment should be used and maintained.
The boats' electrical systems are designed for maximum self-sufficiency and to carry the load of modern electronics and electrical devices. These days it is common for a cruising couple to expend more than 100 amp/hours a day, and those who navigate with laptops and keep radar on at night will expend 250 to 300 amp/hours every 24 hours. To meet this high demand, the new Calibers come with what they call the Smart Electrical System. The system starts
with a battery bank featuring two
200-amp/hour AGM (absorbed glass mat) batteries. Extra heavy power
users may want to bump that up to a total of 600 or even 800
amp/hours of capacity.
The primary generating source will be the high output alternator, which has a cold rating of 110 amps and will have a hot rating of something like 60 to 80 amps. For those who want to use engine power
