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.

Description

Hitia 17 is the perfect beach catamaran, but also capable for use as a micro Coastal Trekker. Her wingsail sprit rig with low centre of effort gives good drive and great stability. The sail can be reefed and hence the boat can always be sailed safely without the risk of capsize, which most other beach cats are prone to. She has skegs and rudders that do not project below the V-eed hull, hence she can be sailed straight off the beach without lifting rudders or daggerboards.

She has stowage space within the hulls and the two self draining ‘cockpits’ are big enough to sit in, or stow camping gear for a longer Trek. The boat can carry four adults. The deck is designed to take a standard two-man dome or pop-up tent, or you can make your own decktent to drawing supplied. Can be carried on the car roof of a bigger car or is easily trailed. A lovely minimalist coastal explorer.
