Find the right boat for you

Wharram Study Plans are intended to help you decide if a particular boat design is for you. They provide more detail than is available in the Design Book. The most important part of the Study Plan is the Materials List, which will list the major boat building materials requirements so you can cost your project in your own area. We feel sure that after studying these plans you will appreciate the quality and detail of the Building Plans.

Study Plans are only available as digital downloads. Downloads are instant access and eliminate delivery costs, which is particularly beneficial for international customers. They can also be printed if you wish.

The Mana 24 design does not have a study plan, comprehensive design information is available on our site.

Many discerning sailors want the PAHI-style, 'flexi space' interior layout in a larger craft as well as the comfort of toilets, showers, a deck steering shelter and a galley sufficient for 6-8 people. So, for them we designed the PAHI 52. The Pahi 52 has also been specially adapted as a luxury skippered charter boat for Archipel Club.

The Pahi 52 is only available professionally built by Andy Smith Boatworks in the Philippines.
