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 3 cabins, 6 berths, a galley, 115.0 liter fresh water capacity, toilet facility and 35.0 liter waste water capacity.
The Buhl 111 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 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.
Buhl 111 may be equipped with an inboard Volvo Penta engine at 18 hp (13 kW). Calculated max speed is about 4.7 knots
The fuel tank has a capacity of 65.0 liters (17 US gallons, 14 imperial gallons).

Meaning: if you load 192 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1080 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 34m2 (365 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.
