With the Activ 505 Open, you’ll want to be on the water all day. Whether it’s for fishing, relaxing, or a bit of both. The boat looks sportive on the outside and feels spacious from within. Just how spacious? Get aboard with up to 5 people and discover its interplay of practicality, ergonomics and comfort. The Activ 505 Open also comes in a Smart Edition that includes its most popular options.


A single Mercury outboard engine with up to 100 hp powers the Activ 505 Open. In other words, safe and smooth navigation is a given. The high freeboard and the ease of circulation aboard add to this secure feeling, both for adults and children alike. Easy access from the bow and an integrated double swim platform encourage activity, going on and off the boat and in and out of the water. A slightly tinted windshield improves the driver’s visibility at all times.


A reclining aft seat optimizes the available cockpit space while still making it possible to tilt the engine entirely. The stylish bicolour helm caters to the driver’s needs, whether you’re seated or standing up. It contains integrated cup holders, a storage tray and a mounting space for a 7” GPS/chartplotter. A footrest makes you feel even more comfortable while behind the wheel. And even with the sun lounge deployed, access to the console remains completely free.


Every section of the Activ 505 Open serves multiple purposes. The bow seating area transforms from a basic sun lounge into an extended one within seconds. And at dinner time, you install the exterior table just as quickly. Moving on to the cockpit, the flip-flop backrest is bidirectional and can be moved forward. That way, the cockpit becomes a socialising area with driver and passengers facing each other. Do you prefer a little less conversation and a little more action? Time to take out the ski mast!


On the bow, a console storage with premium finish inside protects the exterior table and the cushions from bad weather conditions. There is permanent access to this storage space, even with the extended sun deck deployed. Smaller items can be stored safely under the seating. The Activ 505 Open also contains dedicated storage for the ski pole, the navigation light and the sun lounge extensions.

Karsten Washausen
A starter boat that is also suitable for fishing

In search of a boat for day trips and fishing in the Rügen area, I found concluded my search with a Quicksilver. First, I was afraid that the maximum load of 1500 kg was an issue but it wasn’t. I have a trailer with a max load of 1.5 and with the weight of the trailer of approx. 375 kg and a working weight of the Quicksilver Activ 505 Open with an 80 HP Mercury of approx. 900 KG (including the Smart Edition, Radio and Simrad EVO 2) there is still a margin of approximately 250 kg. The Quicksilver Activ 505 Open is easy to steer with the 80 HP Mercury and reaches a top speed of just over 50 km/h with 2 people. The central control unit provides a good overview. Underneath this is a storage space for the seat cushions and the angling accessories. The Quicksilver is stable in the course of the correct trimming and follows the driving instructions well. Only at high speeds and very tight cornering the screw will turn above the water which makes the boat slow down. Critical situations are thus almost impossible and fun is guaranteed. The high freeboard makes the boat also interesting for families with children and offers enough security if you are surprised by bad weather. The low draft of the Quicksilver 505, with a high-trimmed motor, makes it possible come close to shore in in calm bays, or to fish on the water’s side. When changing the location during angling, 2 rods can be safely inserted into the rod holders integrated into the ship's side wall. The only drawback, however, which was already eliminated with the new model series 2017, is the then too small tank with 50 liters. In the new series, a 90-liter tank was fitted. All in all a boat, which I would buy again.
