Specifications
Valiant Vanguard 520 (2011) with Mercury 75 hp and road trailer – sporty RIB for lakes and inland waters
The 2011 Valiant Vanguard 520 is a versatile RIB (Rigid Inflatable Boat) aimed at buyers looking for a sporty, practical and easy-to-handle inflatable with a rigid hull. With a length of 5.20 metres and a beam of 2.00 metres, this model offers a pleasant balance between onboard space and manoeuvrability. Thanks to the polyester V-hull, the boat sits stable in the water and feels direct and controllable underway, making it suitable for both relaxed cruising and more active use on inland waters and lakes.
This Valiant has previously been used as a holiday boat and for day trips, with the emphasis on fun and sporty boating. That character fits the concept of a 5.20-metre RIB well: quick to launch, quick to get up to speed, and easy to load back onto the trailer. The air draft of approx. 1.50 metres also makes it interesting for areas with bridges and lower clearances, while the draft of about 1.00 metre helps you operate in shallower areas as well.
Valiant Vanguard 520 now in the online auction. Anyone can bid up to and including 18 May 2026.
Hull, handling and possible uses
The polyester V-shaped hull is designed to cut through waves and track well, which can be a noticeable advantage especially on open lakes and in stronger winds. A RIB like this is known for its combination of cushioning and stability: the rigid hull provides solid handling, while the tubes add buoyancy and a reassuring feel when boarding and manoeuvring. Steering is via a wheel at a console, giving an active, clear helm position and making docking and turning in tight spaces easier.
For anyone looking for a boat for watersports, fast transfers, or simply a dynamic day on the water, the Vanguard 520 is a logical size. It is large enough to cruise comfortably with several people, yet compact enough to trailer and store without much hassle. This type of RIB is therefore also attractive as a tender, as a leisure boat for a holiday location, or as a sporty family boat for weekend use.
Mercury Optimax 75 hp: performance and experience
On the transom is a Mercury Optimax 75 hp outboard engine with electric start. The engine is operational and, according to the information provided, has 152 running hours, which gives insight into its use. With a 50-litre petrol tank, a practical range for day trips is possible, depending on speed and conditions. Onboard instruments include a tachometer and temperature gauge, helping you monitor engine load and operating temperature while underway.
The stated cruising speed and top speed are around 55 km/h, making this a quick RIB in its class. That translates into a lively boating experience: quick planing, immediate response to steering input, and sufficient power for sporty driving. This is the kind of set-up that suits those who like to make pace on lakes or larger inland waters, while still allowing relaxed cruising when preferred.
Deck equipment and practical details
In terms of equipment, the boat is fitted with a cover, fenders and lines, and a set of life jackets is also included. An anchor is present and is secured with a line. This kind of basic equipment matches the intended use well: day trips, mooring up at a small beach, or lying at anchor during a break.
The boat was last taken out of the water for maintenance in 2025. No osmosis has been reported. However, it is stated that the engine and tubes require maintenance. For a buyer, this offers the opportunity to refresh the boat to their own standards and preferences, for example by focusing on preventive engine servicing and checking the tubes, so the RIB is once again ideally suited to intensive recreational use.
Including Freewheel tilting trailer with registration
An important plus is that this Valiant Vanguard 520 is offered including a road trailer with registration. It concerns a Freewheel tilting trailer (year of manufacture 2005), braked, single axle, with ten rollers and a trailer winch. The payload is stated as 1,700 kg. A tilting trailer makes launching and retrieving easier, especially on slipways where you want to work quickly and in a controlled manner. For buyers seeking flexibility—boating at different locations, winter storage at home, or spontaneously visiting another lake—a complete boat-and-trailer combination makes all the difference.
All in all, this Valiant Vanguard 520 is an attractive option for anyone looking for a sporty RIB with a Mercury 75 hp engine, suitable for inland waters and lakes, with practical equipment and the convenience of an included trailer. This combination offers plenty of opportunities for recreation, watersports and holiday trips, with room to further optimise the boat in certain areas to suit personal preferences.
