Review of Tartan 28 Piper

The hull 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 boat is equipped with 114.0 liter fresh water capacity.

The Tartan 28 Piper 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 Tartan 28 Piper 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 enter even shallow marinas as the draft is just about 1.19 - 1.29 meter (3.90 - 4.20 ft) dependent on the load. See immersion rate below.

Tartan 28 Piper may be equipped with an inboard Volvo Penta diesel engine at 18 hp (13 kW). Calculated max speed is about 6.1 knots

The fuel tank has a capacity of 61.0 liters (16 US gallons, 13 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Tartan 28 Piper is 2.35, indicating that this boat would not 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 6.5 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 Tartan 28 Piper is about 159 kg/cm, alternatively 895 lbs/inch.
Meaning: if you load 159 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 895 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Tartan 28 Piper is 2.60.

What is a Ballast Ratio?

The ballast ratio for Tartan 28 Piper is 36%.

What is Displacement Length Ratio?

The DL-ratio for Tartan 28 Piper is 212 which categorizes this boat among 'light crusers & offshore racers'.

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

The SA/D for Tartan 28 Piper with ISO 8666 reference sail is 18.1, with a 135% genua the SA/D is 21.5.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 24m² (258 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.
