I'm building a sailing ship, not a 'sail boat' I am wondering if I can design it to outrun a powered yacht.
Let's make this a hypothetical so no-one argues about a nonexistant ship. I just want an average top speed.

This is fastest sailboat on the planet - 59 knots.

World fastest power boat -317 mph

Fastest Yacht - 70 knots

Thanks

You have not defined the "race course", and that makes a big difference.
The current record for a non-stop circumnavigation is held by a sailing vessel, not a stink pot. As the courses get shorter and less challenging, the stinkers get the nod.

Cheers,

Jim

PS: And the nonstop record is held by a hundred odd foot trimaran, not a a "sailing ship".

BTW - the theoretical hull speed for a "sailing ship" will be 1.34*sqrtLWL. LWL is load water line, basically the length of the vessel at the waterline. For example at boat with an LWL of 36 foot has a theoretical hull speed of about 9 knots. The only way to exceed that is to get the boat up on a plane.

Not quite true.. This is only true for reasonable leingth:width boats. Fast displacement hulls can stay in displacement mode at much higher speeds.

If you are building a sailing ship then look to the old Yankee Clippers, they held some of greatest speed x distance records for many years, wouldn't beat a power vessel on a short run, but for round the horn, I would put my money on the Clipper ships of the days gone by.

Thank you. and yes I am I think this is the only decent (not to mention promising) answer I've got

Really? You're building a sailing ship? And you're wondering what?

Oh. You're wondering whether you can design a sailing ship to outrun a powered yacht. Hmmm. So you're not only building a ship, but you're designing it too. You are designing a sailing ship even though you need to ask an interned forum about "average top speeds."

Really?

If ya are for real, you would really do yourself some good by looking at the West Coast Lumber Schooners!! They made trips in the Pacific that many of to days Raceing Yachts would envy !! just sayin ya need to do some home work !!

You also might want to look up the "Blue Dolphin" she is still at harbor on the east coast, in her time she was a very fast sailing vessel.
