About Calista

Calista is a 2010 Leopard 46 catamaran, 3 cabin “owners version”. We bought her in November 2019 with the goal of spending several years sailing western Mexico and the South Pacific.

2020 was all about Covid and a major refit. In the refit, Calista got new nav electronics, new batteries, new standing rigging, a water maker, solar panels, a sat phone for emergencies and offshore weather forecasts, and a washing machine. We are setup for offshore cruising with a safe and solid ‘home on the water’ which includes space for comfort and toys.

When we redid the standing rigging we converted to an in-boom furling mainsail. The main advantage is that reefing is just a matter of rolling up some of the sail, eliminating all the reefing lines.

We use our mainsail and jib most of the time (see pic above). We can sail upwind to about 35 degrees, apparent. If the winds are light and not too far forward, we raise the Code0 from our bowsprit.

For downwind sailing we use our big asymetrical spinnaker (aka “The Giant Pumpkin”) which can be flown from the bowsprit or from the bow of the upwind hull. I love downwind sailing in the trade winds!

The house batteries can be charged from the solar panels, the generator, or from shore power. Calista has two 30 amp plugs for shore power. One goes directly to the inverters to charge the ‘house batteries’ and can also directly power the AC outlets on the boat. This means it can only be used with 120v 60 Hz AC which is predominant in the US, Mexico and a few other places. Most of the rest of the world uses 220v 50 Hz AC so I setup the second shore-power plug to go to a device that can take any voltage from 90v to 260v and any frequency from 40 Hz to 80 Hz and converts this to 12v DC to charge the house batteries. This can handle pretty much any shore power we might find anywhere in the world.

The engines both have stock 60 amp alternators (in reality we get about 20 amps) that charge the engine start batteries. For each battery, I also have a device that sends DC charging current to the house batteries once the engine batteries are full.
