Review of Trintella IV

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The boat is equipped with 500.0 liter fresh water capacity.

The Trintella IV is equipped with a ketch rig. A ketch rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a ketch allows for better comfort and stability when sailing downwind or on a broad reach.

Full keel

The Trintella IV is equipped with a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

The boat can enter most marinas as the draft is just about 1.55 - 1.65 meter (5.09 - 5.39 ft) dependent on the load. See immersion rate below.

Trintella IV may be equipped with an inboard Perkins diesel engine

The fuel tank has a capacity of 151.0 liters (39 US gallons, 33 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Trintella IV is 1.62, 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 8.5 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 Trintella IV is about 294 kg/cm, alternatively 1648 lbs/inch.
Meaning: if you load 294 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1648 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Trintella IV is 3.59.

What is a Ballast Ratio?

The ballast ratio for Trintella IV is 39%.

What is Displacement Length Ratio?

The DL-ratio for Trintella IV is 164 which categorizes this boat among 'light racers'.

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): 12.70

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 47m² (505 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.
