Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.
The Olla 9 is equipped with a long keel. A long 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.
Olla 9 can enter even shallow marinas as the draft is just about 1.20 - 1.30 meter (3.94 - 4.24 ft) dependent on the load. See immersion rate below.
The boat is typically equipped with an inboard Vetus diesel engine at 65.0 hp (48 kW).
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 150.0 liters (39 US gallons, 32 imperial gallons).
