But even a "massively heavy" carbon rudder would be far lighter than one of your weldments. And,,,,ta dahhh,,,they don't rust. But I agree with you. There is a place for your approach. You have your home builder market and good for you. Home builders need a designer who has done all the "dirty work" of actually building a boat. You've got me there. I can't build anything. Your way is one way. There are many other ways. I take pride in seeing my designs built by skilled yacht builders. I have my own niche.

I love beautiful yachts.

But I'm not here to try and convince you, just to let other readers and posters know that you represent an extremely narrow and semi-educated perspective when it comes to engineering of yacht structures.

Here is a pic of WILD HORSES, welded alu hull, carbon deck and deck structures, carbon spade rudder and a family of proven offshore cruisers ready to take WILD HORSES offshore again. This boat is a very comfortable rocket, beautifully balanced and a joy to sail, a peach under power around the dock. I'm very proud of this one. Beautiful isn't it?

Just curious, glad all those rudders don't break off, but why do so many of your boats end up on the rocks?
The steel keeping my skeg on is, at 60,000 psi tensile strength, 2.7 million pounds tensile strength.
And you say a carbon figleaf rudder is strong enough to take the stern off my boat , stonger than 2.7 milion pounds tensile strength?
Ya sure , and do you also have some ocean front property for sale in Kamloops?
What's the price tag on all that Carbon fibre? Enough for me to cruise for a decade? Would I give up a decade of full time cruising, to be able to go marginaly faster? Not a chance!
I notice plastic boaters fear hitting logs, etc in the night, and often worry about getting in after dark. Would I give up care free, moonlight winter sails, for a marginally faster sail, in daylight only? Not a chance!
My boats sometimes go aground because they are not used as marina queens, and do a lot of cruising, sometimes in uncharted waters. If you aint been aground ,you aint been around. Yes, some of their skippers are piss poor navigators. I dont choose my clients on that basis , neither do you.The first owner of a 36 was my demolition test pilot. Any other boat wouldn't have survived as long in his hands. Nothing proves a boat strength like a piss poor navigator- demolition test pilot. How they sail is out of my hands. Are you claiming that owning a Perry design automatically makes the skipper a good navigator , no experience neccessary?
People choose my designs for the freedom from worry about hitting anything, over going marginally faster, at the price of constant worry about hitting anything. With my first boat, I had to worry about such things .When I switched to steel, and drasticaly reduced such worries my enjoyment of cruising went up drastically, far more than any enjoyment which going marginally faster would have given me.
That is why my boats cruise so much, and dont cling to marinas, waiting for fair weather sailer days, or seasons.
In 38 years with steel rudders, I havent had a rust problem. As long as your zinc is on and in good contact, it has to go first, before the rudder can start corroding. Outboard rudders can be easily removed, hung in a tree and painted , with no need or an expensive haulout.
Readers should know they have an alternative to super expensive boats , which you have to constantly worry about hitting anything with, deck leaks and gear pulling out of the decks, and have the option of a marginally slower boat, which is extremely worry free, on which nothing breaks . The choice is theirs. My clients choose the latter.

I live on the BC coast, cruising year round, while those with more fragile, trendy, and expensive boats go to work to pay the moorage, and loans needed to own and maintain them. I consider their lives "living in a cave" far more than mine.They are far more likely to be your clients than mine. I love to wake up in a secluded anchorage, turn on the traffic report, and listen to what they are doung to pay for that fragile plastic boat they bought to impress us with . I cut a fart in their honour and go back to sleep for an extra hour or two, thoroughly "impressed."
Later, I get up and enjoy my latest "cave," pristine , deserted anchorages, which they work all year to spend a couple of weeks in.
Efficiency is relative to what you are trying to accomplish.
