Review of Standfast 33

Both the hull and the deck is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.
The deck is a double deck which improves the indoor climate.

The interior is like many other boats made of mahogany.
The boat is equipped with 2 cabins, 5 berths, a galley and toilet facility.
The headroom is above average

The Standfast 33 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 1.87 - 1.97 meter (6.14 - 6.44 ft) dependent on the load. See immersion rate below.

Standfast 33 is typically equipped with an inboard Bukh diesel engine at 27.0 hp (20 kW), which gives a max speed about 6.0 knots.

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

The fuel tank has a capacity of 49.0 liters (12 US gallons, 10 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Standfast 33 is 1.92, 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 6.7 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 Standfast 33 is about 164 kg/cm, alternatively 921 lbs/inch.
Meaning: if you load 164 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 921 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Standfast 33 is 25.5.

Comparing this ratio with similar sailboats show that it is more comfortable than 54% of all similar sailboat designs. This comfort value is just above average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Standfast 33 is 3.12.

Compared with other similar sailboats it is more spacy than 58% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Standfast 33 is 38%.

This ballast ratio shows a righting moment that is higher than 34% of all similar sailboat designs. A righting moment (ability to resist heeling) just below average.

What is Displacement Length Ratio?

The DL-ratio for Standfast 33 is 296 which categorizes this boat among 'medium weight cruisers'.

27% 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.

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

The SA/D for Standfast 33 with ISO 8666 reference sail is 16.9, with a 135% genua the SA/D is 20.4.

The SA/D ratio indicates that it is faster than 54% of all similar sailboat designs in light wind.

The Standfast 33 has more rig than 58% of all similar sailboats, which indicates that the boat is slightly overrigged.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 29m² (312 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.
