The boat is equipped with 0 cabins, 9 berths, a galley and toilet facility.
The Pacific 555 is built with a ketch rig. A ketch rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a ketch allows for better comfort and stability when sailing downwind or on a broad reach.
Unknown keel type
The boat can only enter major marinas as the draft is about 2.20 - 2.30 meter (7.22 - 7.52 ft) dependent on the load. See immersion rate below.
Pacific 555 may be equipped with an inboard Perkins engine at 90 hp (67 kW). The speed is 9.5 knots.
Sailing characteristics
This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Pacific 555 is 1.75, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Pacific 555 is about 462 kg/cm, alternatively 2588 lbs/inch.
Meaning: if you load 462 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2588 lbs cargo on the boat it will sink 1 inch.

SA/D (Sail Area Displacement ratio)
Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 20.35
