Looking for a new boat? Find a Wibo 930 or similar boat for sale
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.
The Wibo 930 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 Wibo 930 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 enter even shallow marinas as the draft is just about 1.38 - 1.48 meter (4.53 - 4.83 ft) dependent on the load. See immersion rate below.
Wibo 930 may be equipped with an inboard Volvo Penta engine at 25 hp (18 kW).
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 Wibo 930 is 1.75, indicating that this boat could - if evaluated by this formula alone - 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 Wibo 930 is about 180 kg/cm, alternatively 1011 lbs/inch.
Meaning: if you load 180 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1011 lbs cargo on the boat it will sink 1 inch.

The ballast ratio for Wibo 930 is 33%.
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): 16.16
