Review of Baltic 55 DP

Both the hull and the deck is made of hand laid fibreglass. Generally, a hull made of hand laid fibreglass requires only a minimum of maintenance during the sailing season.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.
The deck is a double deck which improves the indoor climate.

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with 0 cabins, 8-10 berths, a galley, 750.0 liter fresh water capacity and toilet facility.

The Baltic 55 DP is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

Fin keel

The Baltic 55 DP is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can only enter major marinas as the draft is about 2.42 - 2.52 meter (7.94 - 8.24 ft) dependent on the load. See immersion rate below.

The Baltic 55 DP has been equipped with different engine alternatives.

Alternative 1:

Baltic 55 DP may be equipped with an inboard Yanmar 4JH3-DTE diesel engine at 125 hp (93 kW). Calculated max speed is about 9.2 knots

Alternative 2:

The boat may be equipped with an inboard Volvo Penta TMD 30 diesel engine at 86 hp (64 kW). The speed is 9.5 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.

The fuel tank, which is made of stainless steel, has a capacity of 330.0 liters (87 US gallons, 72 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Baltic 55 DP is 1.91, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 9.2 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Baltic 55 DP is about 476 kg/cm, alternatively 2665 lbs/inch.
Meaning: if you load 476 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 2665 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Baltic 55 DP is 3.39.

What is a Ballast Ratio?

The ballast ratio for Baltic 55 DP is 42%.

What is Displacement Length Ratio?

The DL-ratio for Baltic 55 DP is 161 which categorizes this boat among 'light racers'.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 79m² (850 ft²).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
