With the new 725 Pro T-Top model, Sting Boats presents a further development of its successful 725 series. The new model combines the proven hull construction with a weatherproof T-top superstructure and is aimed at water sports enthusiasts who are looking for a versatile boat for a variety of uses.

Proven hull construction

The striking new feature is the eponymous T-top, a fixed roof over the helm position. This offers protection from the sun, wind and rain without restricting freedom of movement on board. In contrast to a full cabin, the boat's character remains open, which is particularly advantageous when fishing or travelling for work.

The hull construction is characterised by a reinforced keel, which provides additional protection in the event of grounding and in shallow water. The high freeboard increases safety even in rough conditions.

New engine option with Mercury V6

With the introduction of the 725 Pro T-Top, Sting is expanding its engine options to include the Mercury V6 150 hp (110 kW) outboard. This six-cylinder engine is characterised by a high torque in the medium speed range, which has a positive effect on acceleration.

The V6 engine offers faster gliding compared to the previously available engine versions. It also runs more smoothly and quietly, which increases comfort, especially on longer journeys. Sting states that the engine offers sufficient power reserves even with higher loads and in demanding conditions.

Sting comes with practical equipment

The cockpit layout has been designed with functionality in mind. The helm station offers space for modern navigation electronics and is ergonomically designed. The open deck design offers plenty of freedom of movement and can be used flexibly, whether as a fishing platform, for transporting equipment or for leisure activities. The T-top not only offers weather protection, but can also be used to attach fishing rods, aerials or lighting.

Like all models in the Pro series, the 725 Pro T-Top is designed for year-round use. The robust construction and well thought-out details make the boat a reliable companion for different weather conditions. The combination of open deck and protective T-top offers a good compromise between weather protection and flexibility.
