Lots to report with progress on many fronts.One of our Paradox V2 A Cat prototypes (the orange boat AKA ‘Glennis‘) has raced in several evens in Victoria, skippered by young Tom Stuchbery. Feedback is extremely encouraging. Overall we are now certain that the concept works well. The boat is consistently fast, especially upwind where it can...Read More

Many have asked me to comment on proposed changes to the A Class Catamaran Rule. Questions fall in two areas: is a change necessary, and what should the revised restrictions be?My position is that, as a manufacturer, our task is to work within the rules, not to influence them. Therefore CarbonicBoats will comment publicly when...Read More

With the A Cat Europeans and Australian Nationals coming up, it is a very exciting time in the class. Paradox will not be at these events as we are well into finalising the production design that, as you will see very soon, is a totally new boat with most key concepts re-visited. Looking back at...Read More

In response to numerous requests, and with the 34th America’s Cup almost upon us (short on teams but rich in technical curiosities), here is a ‘back to basics’ look at multihull foil solutions. This post samples the main varieties of multihull foil, assuming some background sailing knowledge. Angled Board The simplest way to obtain a...Read More

Another video of Paradox starting to properly exploit new stable foiling setups. Stability is heavily influenced by the relative lift contribution of rudder winglets and main foils. We now set up the rudders to provide some upward lift when the boat is at neutral trim. If driving force from the sail increases, causing the bow...Read More

A short video from a recent testing session. Our understanding of the settings necessary for sustained stable foilborne sailing is steadily improving. It is worth re-iterating the definition of stable flight with reference to the feedback loop that arises when external forces upset pitch angle and ride height. A stable setup settles on an attitude...Read More

As already mentioned, we have spent lots of time on the water recently, with different foil concepts, testing, evaluating and tuning. Some tests with Paradox sailing alone and some in the company of other known fast A Cats. It is safe to say that we are getting a handle on key issues and how they...Read More

Lots of testing in the ‘off season’. We completed some very productive sessions over the past few days and have more planned. As some of you may have observed, we went through some different concepts to the initial S foil setup. We are working on several areas for both numbers and feel, testing initially alone,...Read More

This is the second post in response to questions we are receiving frequently, mostly in connection with design choices on Paradox and how they may compare to developments seen elsewhere. I have added ‘FAQ’ as a label so in future these posts can be filtered out by those (fellow sailing nerds) who are interested… Why...Read More

A few images to further explain some characteristics of our Version 1 S foil configuration. Posted in response to questions sent in by some of you. Firstly the effect of foil rake on the angle of attack of the horizontal part of the foil, the part that provides lift in the up/down direction: In the...Read More
