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 Gulfstar 60 has been built with different keel alternatives.

Unknown keel type

The boat can only enter major marinas as the draft is about 2.04 - 2.14 meter (6.69 - 6.99 ft) dependent on the load. See immersion rate below.

CentreBoard

One option is a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can only enter major marinas as the draft is about 3.81 - 3.91 meter (12.50 - 12.80 ft) dependent on the load. See immersion rate below.

Fin keel

Another option is a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

Gulfstar 60 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.

Fin keel

Another option is a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The boat can only enter major marinas as the draft is about 2.74 - 2.84 meter (8.99 - 9.29 ft) dependent on the load. See immersion rate below.


Engine

The boat may be equipped with an inboard Perkins 6.354 T diesel engine at 165 hp (122 kW). Calculated max speed is about 8.4 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.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Gulfstar 60 is 1.61, 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 9.3 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 Gulfstar 60 is about 481 kg/cm, alternatively 2695 lbs/inch.
Meaning: if you load 481 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 2695 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.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Gulfstar 60 is 3.78.

Wide Slim 69% 0 50 100
Compared with other similar sailboats it is slimmer than 69% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Gulfstar 60 is 249 which categorizes this boat among 'light crusers & offshore racers'.

Heavy Light 21% 0 50 100
21% 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)

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Gulfstar 60 with ISO 8666 reference sail is 15.8, with a 135% genua the SA/D is 18.8.


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 76m2 (818 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.
