With the T9, Finnmaster aims to combine sportiness with living comfort. The top of the Finnish T-series demonstrates strong handling characteristics, even when cornering at over 50 knots.

The Finnmaster shipyard has been known for 30 years for building robust boats for Scandinavian waters. The T9 is designed to combine fun and comfort with the safety features that make it suitable for sailing in rough weather.

Stable in the curve

Anyone who sits behind the wheel of the T9 and presses the throttle will soon have a smile on their face. With a length of 9.04 metres and a maximum engine output of 800 hp, the T9 can reach speeds of over 50 knots. It is also stable in bends and can be manoeuvred precisely. Even at a speed of 42 knots, she can be steered hard without the stern becoming unsettled.

Thanks to the ergonomically shaped seats at the helm, you don't lose your footing and remain stable even with high lateral forces. In general, the skipper is well protected by the windscreen so that high speeds are not even noticed. However, it quickly becomes windy in the rear seats.

Finnmaster T9: Layout

The living area on deck offers plenty of space. There is a large lowerable table and an L-shaped bench seat at the stern. Here you can either have dinner or create a spacious sunbathing area with the table folded down. There are also two small platforms aft for easy access to the boat. A small galley is located opposite the bench seat: a hob, a small sink, a storage shelf and a refrigerator. Nothing special, but enough to prepare a small meal.

A narrow access hatch through the windscreen leads to the minimalist foredeck with a padded sunbathing area. The T9 can also be fitted with an optional T-top, which offers even more protection from rain and sun, especially for the seating area.

Comfortable living for four people

The Finnmaster T9 offers space below deck for a total of four people. The spacious bed in the bow is large enough for two guests. Elongated windows on the sides and the emergency hatch on the ceiling bring plenty of natural light into the cabin. A bench seat has also been installed on the port side, right next to the narrow staircase that provides access to the interior.

A small wet room is easily accessible and offers everything you need, including a small window for fresh air supply. The second berth on the day cruiser is cleverly positioned. There is a flat cabin next to the stairs and below deck. However, access is somewhat difficult as there is only a mattress on the floor. Once in the reclining position, there is a cosy sleeping area with sufficient ceiling height. However, two adults will need to be prepared to compromise, as access to and from the lower cabin is quite narrow. There is no separation between the two beds, such as a door.

The interior is well equipped for a day cruiser. A family with two children in particular should find plenty of space here, even for several days. But one thing should be noted: The Finnmaster T9 lacks storage space, especially for longer trips without going ashore. Especially below deck, this is rather tight.

Motors and specifications

The 9.04 metre long and 3.25 metre wide boat displaces 3,450 kilograms with a draught of 56 centimetres. The T9 has a GRP V-hull and is certified for coastal waters in accordance with CE category C. There is space for up to ten people on board, and four berths are also available. The boat is equipped with tanks for 420 litres of fuel, 90 litres of fresh water and 60 litres of sewage to ensure an appropriate range.

The power spectrum ranges from 300 to 800 hp. In test runs with two Mercury Verado V10 400 outboards, the T9 reached a top speed of 54.0 knots. At a cruising speed of 34 knots, the consumption of the Mercury engines is 2.3 litres per nautical mile according to the manufacturer's specifications, which is definitely a standard market value for this performance class.


Weit entfernt von den Küsten im Rhein-Main-Gebiet aufgewachsen, fand David Ingelfinger erst im Alter von elf Jahren auf den niederländischen Gewässern zum Segelsport. Was als Familienurlaub ohne großartige Vorkenntnisse begann, mündete in einer steilen Lernkurve, aus der die dauerhafte Leidenschaft fürs Segeln entsprang. Seine praktischen Erfahrungen festigte er über die Jahre mit dem Erwerb des SKS und zahlreichen Meilen als Skipper auf Charteryachten im Ijsselmeer, der Nordsee sowie im Mittelmeer. Nach seinem Studium der Publizistik schlägt er nun die Brücke zwischen dem journalistischen Handwerk und der Praxis auf dem Wasser und bringt seine Begeisterung für den Sport als Volontär in die Redaktion der YACHT ein.
