Review of Colina 36

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

The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 6 berths, 700.0 liter fresh water capacity and 45.0 liter waste water capacity.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

Rig of Colina 36 anno 1991. Masthead rig

The Colina 36 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.

Unknown keel type

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.

Colina 36 can enter most marinas as the draft is just about 1.70 - 1.80 meter (5.58 - 5.88 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Volvo Penta diesel engine at 87 hp (64 kW). The speed is 9.0 knots.

The fuel tank has a capacity of 600.0 liters (158 US gallons, 131 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Colina 36 is 1.44, 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 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.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Colina 36 is about 243 kg/cm, alternatively 1364 lbs/inch.
Meaning: if you load 243 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1364 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Colina 36 is 51.8.

What is L/B (Length Beam Ratio)?

The l/b ratio for Colina 36 is 3.26.

What is a Ballast Ratio?

The ballast ratio for Colina 36 is 33%.

What is Displacement Length Ratio?

The DL-ratio for Colina 36 is 307 which categorizes this boat among 'medium weight cruisers'.

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): 9.86

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 41m² (441 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.
