Design 146, at 18'6" the third largest of our Pocket Cruisers, is a roomy, robust and sea-kindly sail boat, with an excellent cruising accommodation. She was designed in 1999 for a builder in Ireland who wanted a little more accommodation than Design 119, and specifically a separate toilet compartment. This first boat completed building in 2001.

She is very straightforward to build on six laminated ring frames and a laminated backbone. And though ring frames take a little longer to produce at the start, they lead to a much faster and more accurate completion overall. They have a great advantage when it comes to completing the deck and superstructure – often in fact a more difficult task than building the hull. But instead of being confronted by an empty hull upon turn-over, the basic structures are already there, just waiting to be skinned over with the coamings, deck ply and coachroof ply, making it a very much simpler job altogether and a great time-saver in the project as a whole.

The hull skin can be epoxy ply lapstrake as shown here or cold-moulded wood-epoxy. Both skin types give a strong, rigid and relatively lightweight, long-lasting low-maintenance structure. Construction throughout is using WEST™ system boat-building epoxies.

Accommodation is for three, with full length comfortable berths. The galley features a sink unit with stowage beneath and a cook stove unit, again with stowage beneath. The WC, in a separate compartment to port, also has lockers outboard and can have a hanging locker under the cockpit seat if wished. Oilskins can hang under the bridgedeck (on the outboard version - on the inboard engine version, this space is mostly taken up with the engine). Forward of the WC compartment there is a sideboard unit, with stowage beneath. The furniture units are stylish and practical.

The cockpit is roomy, well-protected and comfortable; and long enough for two additional full-length berths with a tent over the boom if wished, giving a camping accommodation for five in total.

With the outboard engine version, the outboard is semi-permanently mounted in a well in the cockpit. This gives convenient reliable performance under power and is not easily flooded even in heavy following seas – and the vessel’s balance and steering is not compromised in any way.

An inboard diesel engine can be fitted instead of the outboard if wished - but there are minor differences in the structural items so this needs to be decided from the start.

The boat is easy to trail, launch and recover and the rig is quickly set up. She has an external lead ballast keel to give excellent stability and a centreboard to give good up-wind ability. She turns in a sparkling performance under a wide variety of conditions and rig combinations.

The detailed and accurate plans together with true step-by-step building instructions carry builders, professional and non-professional alike, through the building process simply and easily. And for larger boats particularly, they allow a managed build to be carried out very successfully. Plans are fully dimensioned; no scaling or lofting is required. The plans and instructions are practical, clear and detailed, containing everything required to build and complete the vessel. Where CNC cutting files are included, or available, they can be sent directly to a CNC facility as required. Professional technical support throughout the build, is available by email, via the forum or by regular mail. More plan info
