The Nauticat 33 is a 33’1” monohull motorsailer designed by Wilho Aarnipalo. She was built by Nauticat Yachts (Finland) and made of monolithic fiberglass / polyester. This yacht was produced between 1967 and 1997 with about 1500 hulls completed.

The Nauticat 33 was the design which propelled Nauticat into mass production boat building. Proving to be immensely popular around the world the model had a production run spanning almost 20 years before making way for the new Nauticat 331. Offering a huge amount of living space for a vessel of just 10 meters in length the design found favour with cruisers and liveaboards alike.

Built in the early days of GRP mass production boat building. Nauticat 33’s were constructed when builders used substantially more material in the lay-up of the hull and deck mouldings than they do now. This heavy lay-up created very resilient finished mouldings which have withstood the rigours of use extremely well and have a long service life ahead of them. Combined with the hull the shape of the deck and wheelhouse moulding completed that un-mistakable Nauticat silhouette.
