Cruising Features of the Wavelength 780

Cruising on the Wavelength 780

A proving cruise was undertaken on the prototype in September of 2008 off the Queensland coast from Rosslyn Bay to the Percy and Duke Island groups and return. ‘Wavelength’ carried full provisions, and kit for three crew for a fortnight, including 180 litres of ice/water combined, 40 litres of fuel, extra battery, spare anchor chain,  a rail mounted BBQ and at times, carrying the ply dinghy plus dinghy outboard on the nets. This amply illustrated the safe cruising displacement of the vessel.

Other cruising features:

One of the advantages of the shallow draught tri is the ability to pull into a sandy beach to spend time ashore. Should the boat be left stranded inadvertently by a receding tide, it is reassuring to know that the bottom of the hull is strong enough to handle the vagaries of an unexpectedly pebbly bottom, or wind driven wave action, as the boat bounces around on a returning tide. A combination of a solid timber core to the laminated hull, glass reinforced bottom, lightweight internal keelson, and a shallow external keel or “shoe”, to take main hull grounding loads and trailer loads, provides relative peace of mind in these conditions. This is not always the case with a more vulnerable foam sandwich hull.
Another desirable cruising feature of the vessel is its capacity to lie to its anchor without “skating,” in all but extreme ‘wind against tide’ conditions. The designed relatively deep forward sections of the main hull allows the boat to lie steadily to its anchor in the same manner as most monohulls, depending on tide direction, without the annoying habit, characteristic of many small tris, of skating around on their anchors in a wide arc at the whim of local wind conditions.

The internal layout is designed for comfort to suit the cruiser. This includes a wide comfortable, easily accessible “Skipper’s” wing-berth to starboard with large storage lockers beneath, including storage for a dinette table and bulky items of kit such as medium sized gear bags, sleeping bags etc.  There is a wing-berth to port and a settee, both with storage under, while the settee may also be extended, if needed, to make a child’s berth. There are window views through the cabin windows from the wing-berths.

A snug double (or luxurious single) berth with comfortable sitting height, is situated forward with handy shelves and locker space. Additional sleeping for one can be had under the cockpit for week ending if required, however, this area is best reserved for storage of sails, boom tent and other bulky items to keep the cabin clear. There is a fitted galley with two burner stove to starboard and sink to port, supplied by a flexible 50 litre water tank located under the forward berth.

Ample locker space is provided for the usual kitchen items and cruising paraphernalia.
A built in 40-60 Litre icebox is located under the starboard forward cockpit seat. There is the room to fit a small compressor alongside under the aft beam box frame, to convert the icebox to a full fridge system if desired. Extra power in the form of a small portable generator or solar panels will be required for this however.

A Porta Potti is fitted under the rear end of the forward berth and can be screened off as required.
There is standing headroom in the galley area under the pop top, even when it is closed.

An optional removable ‘swim’ ladder can be mounted on the float side and stowed in the float hatch when not in use, as are other bulky items such as fenders, buckets, spare sails and fishing gear. In these days of environmental concern, any rubbish can be bagged and stored in the floats, for disposal on return to harbour.

Once the basic hull is built, the cruiser can add a range of additional features and little luxuries to suit such as CD sound systems, 12v portable flatscreen TV, cockpit awnings at anchor, to name a few.
