Basic specs.
The Polaris 43 is a large sailboat designed in the late seventies. Only a few boats have been produced.
Here we would have liked to show you nice photos of the Polaris 43.

Hull
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
Keel
The Polaris 43 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 long keel.
The boat can only enter major marinas as the draft is about 1.88 - 1.98 meter (6.17 - 6.47 ft) dependent on the load. See immersion rate below.
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.
Stability and Safety
What is Capsize Screening Formula (CSF)?
The capsize screening value for Polaris 43 is 1.72, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
Theoretical Maximum Hull Speed
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.9 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.
Immersion rate
The immersion rate is defined as the weight required to sink the boat a certain level.The immersion rate for Polaris 43 is about 272 kg/cm, alternatively 1528 lbs/inch.
Meaning: if you load 272 kg cargo on the boat then it will sink 1 cm.Alternatively, if you load 1528 lbs cargo on the boat it will sink 1 inch.
Sailing statistics
This section is statistical comparison with similar boats of the same category.The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.
Motion Comfort Ratio
What is Motion Comfort Ratio (MCR)?
The Motion Comfort Ratio for Polaris 43 is 35.0.
Comparing this ratio with similar sailboats show that it is more comfortable than 73% of all similar sailboat designs.This comfort value is just above average.
L/B (Length Beam Ratio)
What is L/B (Length Beam Ratio)?
The l/b ratio for Polaris 43 is 3.41.
Compared with other similar sailboats it is slimmer than 62% of all other designs.It seems that the designer has chosen a slightly more speedy hull design.
Ballast Ratio
What is a Ballast Ratio?
The ballast ratio for Polaris 43 is 34%.
This ballast ratio shows a righting moment that is higher than 21% of all similar sailboat designs.A righting moment (ability to resist heeling) significantly below average.
D/L (Displacement Length Ratio)
What is Displacement Length Ratio?
The DL-ratio for Polaris 43 is 254 which categorizes this boat among 'light crusers & offshore racers'.
42% of all similar sailboat designs are categorized as heavier.A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.
SA/D (Sail Area Displacement ratio)
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): 16.27
Maintenance
Bottom Paint
When buying anti-fouling bottom paint, it's nice to know how much to buy.The surface of the wet bottom is about 46m2 (495 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.
Rig
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.
