The WALLER 1100 is a full bridge
deck cat built entirely of marine plywood, to produce a sound and
comfortable ocean cruising vessel at a lower cost than is typical of cats
built in most other materials. In this period of ever increasing
costs associated with boat building, the use of plywood and the Wood/ Epoxy
building technique is a sound and economic exercise for the amateur builder.

CONCEPT
The WALLER 1100 is a full bridge deck cat intended to be easy and inexpensive to build, and yet still capable of living aboard and ocean voyages. Because she is intended for extensive cruising, she has been designed with wider hulls for load carrying ability and internal roominess. (We have shown with previous designs that good performance is possible with wider hulls, as hull beam to length ratio is only one aspect of boat performance.)
The design features a medium tech rig for good windward performance, mini keels , o/b motors in raisable carriages for low cost, and 2 alternate internal arrangement choices, as well as variations in the cockpit roof styling.
RIG
The Waller 1100 comes with a medium tech fully battened sail rig as
standard. The standard cat rig today is the typical heavy roached, fully
battened main and 7/8th rig which time has shown to be the most efficient
rig for catamarans.
CONSTRUCTION
The Waller 1100 is all plywood with some timber framing. The multi chine shape of the hulls and the careful design of the deck and turret cabin mean that there are no compound curves on the vessel, thus making the use of sheet plywood very simple. The basic construction is ply skin over an armature of plywood bulkheads and frames and timber longitudinals, with glass sheathing overall on the outer surfaces. Full use has been made of timber / epoxy construction, with timber framing used only where it is necessary, or the more logical option.
ACCOMMODATION
The Waller 1100 comes with two standard alternate accomodation plans (galley up and galley down.) Both arrangement plans feature twin berth cabins forward and a double berth in the aft Starboard hull, with W.C./ Shower compartment to port aft. The galley up arrangement features galley and dinette on the bridge deck, whilst the galley down features a larger lounge area and chart table on the bridge deck and a larger galley in the mid starboard hull.
