From its purchase price, to berthing space and ongoing maintenance, a monohull costs much less than a catamaran. This is partly due to there being a much wider range of yachts available, than what is found with multihulls. For example, Dufour’s Grand Large range offers yachts a little more than 30 feet long, with two double cabins and one bathroom; whilst the smallest habitable catamarans usually measure around 40 feet and have a minimum of three double cabins. Because of this, monohulls are often better suited for small families, or groups of friends. For an equal size, between 40-60 feet, a monohull sailboat will also cost much less than a catamaran; with the price of a 40 foot catamaran often equal to a monohull of nearly 50 feet.
Berthing space is another thing to consider when choosing which type of yacht to buy. A berth for a monohull yacht generally costs 20-50% less than that of a similarly sized catamaran. This is often one of the biggest expenses for a boat owner and should not be neglected if you are looking to keep control of your budget. When you set sails, berths during your stops to fill up with water and food will also be much less expensive for you.
The monohull has one last advantage: it has a relatively small surface in the water and it’s light; making it easier to get it out of the water, and meaning its regular maintenance (refitting, anti-fouling etc) is less expensive.
