Centre console boats are particularly popular with beginners, as the large amount of space in the cockpit offers sun-seekers, swimming enthusiasts, divers or anglers plenty of room to move around and storage space for equipment to spend a relaxing day on the water with the family or other crew. The bow seating area can be converted into a sunlounger with the optional sunbed extension. There is a large storage space under the stern bench seat where this sunbed extension can be stored when not in use. The lid is held open by a spiral spring, which in our opinion is a rather unsafe mechanism - a gas pressure damper would be better. Two compartments next to the engine sump provide additional storage space for lines or a stern anchor.
However, you need small fingers to open these because the cut-outs are too small. The same applies to the cover of the self-draining anchor locker in the bow. The YO! OPEN 590 is moored to the four well-dimensioned cleats or the towing eye at the bow. The crew can attach fenders to the railing and there is a choice of six engine power variants from 60 to 150 hp. Both Honda and Yamaha outboards are available; our test boat was equipped with a Yamaha F 115. This costs 13,829 euros, making it the largest single item on the bill. If you deduct the engine and accessories from the total sum (28,689 euros) for "our boat", the Yo! Open 590 has a starting price of 11,950 euros.
The Lithuanian-built boat cuts a fine figure when sailing. It reacts to weight shifts on board by heeling slightly, but remains exceptionally stable and keeps its direction. A driving characteristic that has a positive effect on long trips. To minimise unnecessary swell and waves, the engine speed is not allowed to rise above 1500 rpm. The speed of around 10 km/h achieved in this way is well suited as a harbour speed. The boat reacts directly to both sides when reversing with the gear engaged backwards. The turning circles to port and starboard were - with the gear also only engaged - one boat length. When engaged forwards, the diameter of the circle is one and a half boat lengths on each side.
The transition from displacement to gliding speed takes place between 2500 rpm and 3300 rpm. Good gliding speed is achieved at 3500 rpm or 18 knots. At this speed, 0.74 l/sm flows from the 107 litre fuel tank through the separate fuel filter to the engine. We measured a top speed of 38.6 knots. Underway like this, you have to refuel after 94 nm (plus 15-% reserve). The Yo! Open 590 glides economically at 4000 rpm (23 knots); consumption in this case is 0.66 l/sm, and the noise level is within a comfortable range at 78 dB/A. For major course changes, the skipper has to take a firm grip on the helm despite the boat's good trim.
The manoeuvres we performed are similar. If the hull brakes slowly as the manoeuvres become tighter and tighter, the steering forces remain high. The reason for this is the mono-cable steering. BOOTE recommends using hydraulic steering for outboards over 70 hp. According to the importer, they want to add a suitable steering system to the list of accessories, and the Elbe and Hamburg harbour were available to us as a test area. For the rough water test, we travelled through the latter with its "special cruising and commercial waves". The hull channelled the spray away from the boat at a shallow angle. Even at high speeds, there was no splash water.
Praise and criticism: The seat bench for the driver and front passenger is a suitable height, but the upholstery is too thin and does not cover the front edge. This can make longer journeys uncomfortable. The bench does not offer lateral support, but there is an adjustable backrest cushion. The positioning of the steering wheel and the single-lever control is well chosen. This means that both can be operated without restriction even when riding in a standing position. The skipper always has the two digital engine instruments in view. The displays simultaneously show revs, speed, trim, fuel consumption, engine temperature and fuel tank level. A compass, electrical system with battery, control panel for horn, lights and bilge pump, main switch, hand bilge pump, powder extinguisher, bathing ladder and 12 V socket at the helm station are standard on the Open 590.
