Building your own boat with Wharram Designs is the easiest and most cost effective way to fulfil your sailing dreams. Wharram Self-build boat plans start from only £100.

We recommended you follow the tried and trusted Wharram process to ensure the boat you build is both the right type of boat for your needs and also one that will match your building skills and expenditure.

  1. Study our Self Build Boats page to familiarise yourself with our range of designs and their unique qualities. For more detailed information read the Wharram Design Book which reviews each self-build boat model and offers a detailed introduction and understanding of the world of self-build catamarans.
  2. Order one or more sets of our Boat Building Study Plans and immerse yourself into the boat builder's mindset; evaluate the costs; the amount of time required to build your boat; where you will build it and where you will eventually launch it.
  3. Once you have decided on the boat that is right for YOU to build, order the Boat Building Plans and become a member of the Wharram World of builders and sailors. You can build a Wharram with very little experience. All Wharram building plans are drawn for the first time builder, so anyone with a modicum of practical ability can build one of our designs. Our Building Plans present quality instruction, guidance and advice for both novice and professional alike. They are all based on decades of actual building experience and thousands of ocean miles sailed, so you know the design will work.

About James Wharram

In the mid 50's, based on his research into ancient Polynesian boat design, James Wharram built the first off-shore Catamaran in Britain and sailed it out into the Atlantic. While the world's yachting community were still dismissing such a design as a worthy sea-going vessel, James was landing his 23'6" 'Double Hulled Canoe' called TANGAROA in the West Indies.

There he built a second 40' Polynesian style Catamaran, RONGO, and sailed it up to New York and back to the UK accompanied by two German women - being the first to sail a catamaran West-to-East across the North Atlantic.

These amazing Trans-Atlantic crossings and the follow up book "Two Girls, Two Catamarans" have etched the name 'James Wharram' into the annals of yachting history.

The quality of the Wharram self-build catamarans is reflected in their popularity, excellence of craftmanship and 'sound sailing qualities'. More than 50 years on - with over 10,000 sets of plans sold and thousands turned into proud vessels - Wharram 'Cats' can be seen in harbours across the world, maintaining the highest reputation for surviving wind and wave.

To register your interest in joining us for this weekend, please fill out the Registration Form. Everyone welcome!

Friday: Once the boats are moored we will have an evening of relaxed Hui-style ‘Bring and share’ food and drink at the Wharram headquarters on Greenbank Road, which is a short walk from the Quay. Our BBQs will be lit to cook your own food. Listen to a briefing for the weekend from our team, meet James Wharram himself and partner Hanneke Boon and share your ‘Wharram adventure stories’ with like-minded Wharram friends around the camp fire.

Saturday: We leave on the early morning high tide (HW at 06:30) for a full day of sailing in ‘Carrick Roads’ and out to sea. We can anchor somewhere for lunch (location depends on wind and weather on the day). More food and talk round a campfire during the evening (bring your own food!, we will not have a BBQ there, so bring your own means of cooking), ending with an overnight camp - either on your Wharram Cat, or on the quay in your own small tent.

Sunday: Leave the quay soon after high water (HW at 07:00) and anchor/raft up in deeper water for breakfast - more sailing and exploring local creeks during the day with a pre-designated break for lunch. Then either make your own way on to your next destination, or sail back to Wharram HQ, to continue home by road.

MANA - Polynesian word for ‘spirit’ given to an object by its maker or the person that uses it.

Due to the present period of financial austerity and increasingly high marina costs, a large number of would-be sailors are having a hard time financing the dream of sailing their own boat. However, there is an economical way to enjoy sailing, by building your own small lightweight boat, keeping it at home and trailing it to the waters you want to sail in, chasing the good weather. This gives the opportunity to explore many more sailing areas than if based on a permanent mooring and at a much lower cost.

In designing the MANA, we explored this idea and looked sideways into the world of camping and have combined the innovative CNC cut “flat pack” boat-building concept with the philosophy of outdoor living to create the unique MANA camper-sailer, specifically designed for trailer sailing. The MANA kit is sold with all the plywood cut out by CNC cutter and pre-coated with epoxy, so building the boat at home will be a bit like assembling a flat-pack. All the parts slot together perfectly so a hull can take shape in a day.
