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

CONCEPT

The WALLER 1100 is a full bridge deck catamaran intended to be easy and inexpensive to build, and yet still capable of living aboard and ocean voyaging.  Because she is intended for extensive live aboard 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 1100 is designed for safe heavy weather performance rather than all out speed, and as such is a medium / heavy displacement vessel.

The design  features mini keels for cruising simplicity , outboard motors in lifting carriages for low cost, and 2 alternate internal arrangement choices.

RIG

The Waller 1100 comes with a medium tech fully battened sailing rig and alloy mast and boom as standard. The standard catamaran 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 this type of vessel. 

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, frames and timber longitudinals, with fiberglass 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 navigation chart table on the bridge deck , plus a larger galley in the mid starboard hull.
