IN THE MARINA
The 646 is a sturdy looking RIB with nice clean lines and comfortable seating for four with storage in the rear locker and within the helm and navigators seat. The deck level is above the water line making a very practical dry deck with self draining and worry free berthing during the rainy months if you are away from port. The transom allows complete trimming of outboard engine clear of the water at rest. With the tubes providing good stability to the boat at rest.
The 646 was very easy to manoeuvre within the confines of the marina, at 3-5mph she produced almost no wake and the engine idling at this speed is almost silent.
From zero to the transition onto the plane the 646 maintains good manoeuvrability with little change in the level attitude. Visibility all round is excellent and the screen provides good clear protection requiring no sunglasses at speed to maintain a forward watch.
TRANSITION TO PLANE
Cornering in the mid speed range was good. Although the hull is stepped there was ample grip and no sliding occurred with both negative and level trim. Cornering to port was favoured due to the propeller rotation and provided a better lean in angle to the turn than to starboard which had a lesser angle although remaining comfortable. At the higher end of the speed range cornering was the same well mannered response.
The 646 represents a very clean, robust and well mannered boat and at no time did it feel like there were negative surprises waiting to surface. It has quiet effortless planning, safe handling and very responsive acceleration. The instrument package with keyless starting was clear and easy to read at speed providing all the information required for an enjoyable coastal passage.
