A Class Catamaran
Ongoing testing with different foiling configurations is confirming that ultimately righting moment will determine top speed. The diagram below nicely illustrates what happens as speed builds.The plot takes a constant true wind angle (heading relative to true wind direction). As boatspeed increases, the component of apparent wind from dead-ahead gets bigger, while the true wind...

Interest in our L foil kits has been overwhelming. We are at full capacity fulfilling orders and have additional tooling in the pipeline to shorten lead times. Will be sure to publish more images and detailed specs as soon as we get a chance. Market demand speaks clearly and people are ‘voting with their wallets’....

Some thoughts following some recent testing with a focus on handling.Specifically, we worked to gain data on how different foil configurations affect dynamic behaviour during turns in strong wind. The results confirmed observations we hear regularly from experienced Moth sailors, as well as those who race foiling multihulls such as the NACRA F20 Carbon FCS:Being...

In Part 1 we looked at straight line sailing.We concluded that foils will always be a hindrance at very low speeds, but will give an advantage at higher speeds. More aggressive setups (read more foil area) are even worse at low speed but, since they allow earlier takeoff, become superior ‘sooner’ (at a lower windspeed...

In response to questions about where catamaran foil design may go in the future, especially if rule constraints are relaxed, here are some thoughts on the incentives driving design choices. If our goal is fastest time around a windward/leeward course, then the considerations are:– VMG upwind.– VMG downwind.– Control at low speed, specifically to bear...

One final reflection about recent events in the A Class, before resuming normal programming.Future posts will focus on hopefully interesting technical commentary, and updates on our projects… Flourishing The last couple of years gave us extraordinary advances in the capabilities of inshore racing sailboats.Arguably the root cause is development in the America’s Cup, where big...

North American A Class sailors recently voted to Remove Rule 8 as a constraint during their events. With my apologies for editing one of the most important texts in history, here is a tongue-in-cheek look at why the move was necessary and successful: We hold these truths to be self-evident, that all men are created equal,...

We now have an opening for a composite fabricator/shipwright. Our workload is growing so we would like to take on another team member.Projects include UAV airframes, customer parts, RC yachts, and our A Class catamaran.A good mix of one-off prototypes for R&D, and production items. If you possess skills in carbon fiber pre-peg construction, with...
