Crowther Buccaneer Wing Mast Design

Question: Can you share any information about a good wing mast design for my Crowther Buccaneer 24 trimaran?

Thanks for your enquiry. You're right that this info is not so easy to find.   So we invited designers to submit their ideas to this site, with the idea that I would review them and pass on anything interesting.  [Updated 2019]

For liability reasons, designers are reluctant to share mast design very broadly, as they have no control over the loading, materials used or the quality of construction, which after all is very important for a mast that is sometimes stressed near to its limit. But with the help of a liability disclaimer, I was hoping that relieved of failure risks, ideas would flow more freely.   Concept designers would be protected by the liability disclaimer as noted below.

Well, that was back in 2010 and in all that time, I only received one design idea and even that was not ideally suited to the Buccaneer.

In the meantime, I have designed and developed two wing mast designs, the plans of which are both now available.  The first and least expensive is a ply and wood design that is lightly sheathed in glass for protection.    This was followed by a new home-buildable design in carbon fiber that is both stronger and lighter.   Since 2014 numerous examples of both designs have been built and proven entirely satisfactory and aerodynamically efficient   For the Buccaneer, I can now confidentally suggest the carbon fiber design .... or for any other small trimaran in need of a mast update.     Go to this page for more details:  Waters Carbon Fiber Wing Mast.

I will of course still be happy to receive info on any new mast design that you wish to share .... just submit this through my contact form.   Thanks!


Mast Design Disclaimer

Because designers have little or no control over the quality of materials used, their integration or the workmanship applied, they can offer NO guarantee on the success of the final product even if nominally built as per plans for a similar application.

The designer cannot be held responsible for any failure or accident caused thereby and the builder/owner must accept that in working to these plans.

We can only state that this concept has been successfully used for one/few/several (delete as applicable) masts of the length and scantlings indicated but in practice, no two masts are identically loaded so it is highly recommended that a proper analysis is conducted before proceeding. Even then, for reasons already noted, the full responsibility for the mast and rig must rest totally with the owner/builder.
