Without doubt the biggest, most expensive and most stressful part of our recent refit to Morgan’s Cloud was the replacement of her mast. First off, why were we replacing the mast at all? Simply put, to buy peace of mind. We had seen several signs that all was not well aloft including, most ominously, cracks [...]

But it should be remembered that Americas Cup boats are designed on the ragged edge of structural engineering [...]
We had an interesting to-and-fro with a reader who thinks that the benefits of carbon fibre for cruising yacht masts are trivial and that the same benefits could be realized in easier and cheaper ways. To understand why this is not so, and why carbon fibre as a mast material delivers such astounding increases in [...]
All the above is great, but this post gets to the real meat: How much did carbon fibre cost? And what did we get for that money? The new mast, excluding some new rigging, cost about US$55,000, as against an aluminum replacement mast, which would have cost about $30,000; a lot of money to us, [...]
Let’s start with the myths: If a carbon fibre mast gets struck by lightning it is toast, end of story. If a carbon fibre mast gets struck by lightning, there is no way to tell if it has been damaged or not, so it must be junked. These two statements are right up there with [...]
