The Coast Craft 560 has been designed from the outset to blend the benefits of a positive buoyancy hull form with waterjet propulsion. The Coast Craft 560 was developed using experience gained in previous projects to supplement the successful Rapid Runner range of river-going jet boats.
Construction and Design
Construction of the Coast Craft 560 is in marine grade alloy. The hull bottom is formed in 5083 alloy, 5mm thickness as standard although a heavy duty option is also available. The pontoons are formed in 3mm 5052 alloy in four sealed sections per side. The transom and the four full length longitudinal bearers are 4mm. The top deck/ superstructure is formed in 3mm while the cockpit sole is treadplate alloy. A tough ultra-high molecular plastic rubbing strip is attached to the gunwales.
The hull design incorporates a delta keel section to facilitate the waterjet intake. The bow sections have a reasonably fine entry while the main chine is heavily turned down tapering to 100mm in width at the transom. A second chine 50mm up and 50mm wide is formed into the pontoons. Deadrise is variable along the length of the hull and is 20 degrees at the transom. The hull length is 5.6 metres but the extended boarding platform aft and anchor fairlead on the bow bring the overall length to 6 metres. Overall beam is 2.25 metres while the chine beam is 1.85 metres.
The cuddy cabin provides two vee berths with plenty of headroom while sitting. The cockpit dimensions of 2.9 metres from the transom to the mid bulkhead and width of 1.65 metres allows plenty of space for fishing and other recreational activities.
Performance & Handling
The hull shape is designed to give a good ride in choppy conditions, with easy and predictable handling characteristics. The finely tapered front pontoons and high bow reduce the tendency for excessive bow lift in big seas, which is an inherent problem with many pontoon boats. The chine design gives good lateral adhesion in hard turns.
The bow and foredeck area of the Coast Craft 560 may be accessed either via the large Maxwell hatch in the for’ cabin or around the 150mm side decks. Strong alloy grab rails are well positioned on the cabin top. The cabin is open to the cockpit to maximise the available space due to the absence of solid bulkheads. The starboard helm is located on a hanging binnacle making access to the cabin area of the boat easy. Full length side trays built in above the pontoons measure 2.3 metres in length and their 250mm depth means plenty of space for storage of rods, boat hooks etc. The flat coamings are wide enough to sit on while fishing.
A particularly useful feature is the 250mm high toe space between the cockpit sole and the pontoons, which makes standing at the side far more comfortable than other pontoon boats. The boarding platform is generous in size being 470mm deep and 2.05 metres across the beam of the boat. It allows easy access in and out of the cockpit.
Various options are available. These include the Mercury Sportjet EFI and Optimax models, various engine and waterjet combinations, or else outboard power of 90 to 130 HP.
