The WALLER TC 750 was designed as an easy to build and sail, low cost multi-hull yacht, which could also be trailed under wide load towing regulations. Designed for a family of 4, the TC 750 is ideal for a couple, or a family with young children. The cabin features a full size double berth, a good sized and easy to use galley, and a small dinette area around which 3-4 can sit in comfort. There is also a seperate toilet compartment with room for a small shower and fold down basin, as well as two large quarter berths aft . At anchor, a boom tent will turn the cockpit into a huge covered living area.

The multi chine hull (flat bottom with 2 chines) is constructed from sheet ply over plywood bulkheads, with minimal timber framing. Construction employs the timber / epoxy building technique, is very strong to stand up to the rigors of trailing, and is simple and straight forward with the entire shell built as a single unit. When turned over, very little is required to complete the vessel.

This yacht features twin dagger boards and rudders.

The rig is a simple 7/8 design, with non rotating spars and utilizing off the shelf fittings. It can be home built if desired. The rig features an assymetrical spinnaker set from a bow pole, but a normal symetrical spinnaker could be used if desired.

Particular care has been taken to ensure that this boat is both a safe and reliable performer, with an emphasis on good cruising performance and accomodation rather than all out racing, in keeping with its intended use as a family boat. Note that its intended area of use is sheltered and semi sheltered waters, and not open water.

Note that this vessel is wider than the standard road trailing width for most areas. With it's wider beam it is designed to be towed only under wide load rules. These vary from place to place, but in general require a permit (usually annual) and have some restrictions, such as towing only in daylight, not towing in built up areas during peak periods etc. etc. The up side is that the wider beam provides greater stability and better accomodations, thus making the vessel more suitable for extended cruising in the areas for which it is designed.

Normally this yacht would live on its trailer at the local yacht club (much cheaper than a berth or mooring) and would be towed occassionally to travel to more remote cruising grounds. Once you have the permit and understand the rules it is very straight forward, but nevertheless, you should check the wide load towing regulations in your local area before purchasing this plan.
