De Avanti is designed based on the idea of the current owner. The construction drawings of three tugboats from the period 1920–1950 were used as the basis for the underwater hull. The section above the waterline is inspired by the harbor tugs built by shipyard Barkmeier in Stroobos around 1985 for Smit Tak in Rotterdam. Gaastmeer Design then developed the design into construction drawings and a complete cutting package. The hull of the Avanti was built in 2006 by shipyard Heijsman in Stavoren, construction number 36. A MAK MV 36 was chosen for the engine, a 4-cylinder slow-running diesel engine with 160 hp at 500 rpm. This engine came from a German inland vessel and was completely overhauled by the owner in the workshop of Bolier in Dordrecht. Reintjes supplied the corresponding reversing gearbox. Thanks to the efficient shape of the underwater hull, the Avanti is particularly economical. The propulsion consists of a 4-blade Lips propeller with a diameter of 1,050 mm, placed in an HR nozzle. The propeller shaft installation was supplied by IHC Lagersmit and equipped with a Suprime seal. As part of the CVO certification, the MAK was replaced in 2018 by a MAN 2866 LXE40, a 6-cylinder diesel engine with a power of 360 hp at 1,800 rpm. The engine meets Tier 2. In combination with the engine, a ZF W320 reversing gearbox was installed with a reduction of 4.5:1 and trolling. The electrical installation was supplied by Piet Brouwer from Urk. The navigation equipment was supplied and commissioned by Radio Holland Delfzijl. The interior was largely executed by Jurjen Mulder from Grou. After the construction of the Avanti, Heijsman built the Poolster, now known as Robbedoes. This ship is longer, wider, and deeper and has a slightly different underwater shape, partly because the engine is placed further back. Over the years, the Avanti has made many journeys, both on the IJsselmeer and at sea. It has also proven itself under heavier conditions, up to wind force 9. The Avanti lies like a seagull on the water, sails comfortably, and takes on very little water due to its excellent hull shape. A characterful and carefully built tugboat with an impressive sailing history. The Avanti is currently available for viewing by appointment at a location in Friesland. For questions and/or to make an appointment, you are welcome at Elburg Yachting 7 days a week.
