The WALLER 880 Cat is a full length bridge deck catamaran designed for family coastal cruising, with the occasional foray further afield. Full length bridge decks have several advantages in smaller cats, in that they provide a stronger hull structure, more deck space, are easier to construct and eliminate the need for expensive bow beam structures. They also eliminate bow netting which needs to be maintained and replaced on a regular basis. Pounding in heavy weather is minimized by keeping the bridge deck clearance as high as practical in a vessel this size. It should be noted that vessels of this configuration have safely completed the longest ocean voyages, including circumnavigations.
The Waller 880 is designed for safe, comfortable family cruising, with bunks for 4 in seperate cabins, and room for 2 more on the dinette in an emergency. It also features a large, functional toilet / shower area, a full size chart table, a large galley, and a huge cockpit for socializing. There is excellent headroom throughout, with over 2 metres in the working hull areas and 1.5 metres over the bridge deck sitting / sleeping area.
For
simplicity and ease of construction the hulls are strip planked in cedar
and glass composite. The bulkheads, deck and cabin utilize plywood for
cost efficiency, but can be constructed from composite panels if desired.
The entire vessel uses timber / epoxy construction, with virtually no additional
internal framing.

The
rig is a simple but efficient 3/4 sloop, with a large sail area for light
weather cruising, easily reefed in heavier weather. Auxiliary power is
from an outboard engine in a seperate pod beneath the bridge deck. This
works remarkably well, and the 880 is very manouvreable under power.
The
vessel features small stubb keels for cruising simplicity, and efficient
spade rudders for positive helm control. Steering as designed is by tiller,
although wheel steering could be fitted as an alternative.
Plans
for the 880 are extremely comprehensive, with 18 sheets of drawings (A1
size), complete written specifications, a builders manual and disks containing
CAD files for the laser or router cutting of the mould frames for those
who wish to save building time.

PERFORMANCE
The Waller 880 has proven to be a remarkable performer in all weather. Since first launching she has on several occassions made daily runs in excess of 100km over the ground (not distance actually sailed) in 10 hour periods, and has clocked a maximum speed of 21 knots (downwind, of course). Recently a timed run up the eastern Australian coastline in strong winds saw her record a run of 20 nautical miles in 90 minutes, an average speed in excess of 20 kilometers per hour. Her performance and handling is exceptional for a 28 ft family cruising yacht.
(Note# - the above performance figures are as advised by the owner of the vessel in question)
