Looking for a new boat? Find a Friendship 33 or similar boat for sale
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 7 berths.
Fin keel
The Friendship 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 full keel.
The boat can only enter major marinas as the draft is about 1.85 - 1.95 meter (6.07 - 6.37 ft) dependent on the load. See immersion rate below.
The Friendship 33 has been equipped with different engine alternatives.
Alternative 1:
Friendship 33 may be equipped with an inboard Volvo Penta diesel engine
Alternative 2:
The boat may be equipped with an inboard diesel engine at 18 hp (13 kW).
The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.
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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Friendship 33 is 2.06, indicating that this boat would not be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Friendship 33 is about 213 kg/cm, alternatively 1193 lbs/inch.
Meaning: if you load 213 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1193 lbs cargo on the boat it will sink 1 inch.

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): 19.37
