Further to the sailing thread we had recently.

I thought I'd post this picture because, well, I just like it.



It's a pretty big Schooner, maybe around 100 feet, going absolutely flat out.
You can see the wave it's making very clearly with one crest just under the bow and the next crest just under the stern. The wave is as long as the boat. That's what hull speed looks like on a displacement boat people.

 Beautiful . John , is a boat this large capable of making "A Day"? Faster maybe ?

 Dusty

[johnr]

Not quite sure what you mean by a" Day" Dusty.

 A steady 8.3 knots . Just something I read somewhere , know nothing about boats

[Triple Jim]

If the waterline length is 100 feet, the hull speed is about 13.4 knotts.

[PJPR01]

I can knot fathom how any boat can go that fast!  :)

    Yeah , physics ain't my forte either

I don't know the term "A day" but the longer the boat is the higher is the hull speed of the boat.

The big container ships cruise at around 18-20 knots and top out around 25-30 knots depending on the type of vessel.

Maersks old flagship vessel the E-class could top 28 knots. I believe the B-class could do more than 30 knots.

The biggest ship in the fleet now is the Triple-E class and is not build for speed but capacity, so they can't reach the high speed of the older vessels.

I have logged 9 knots in my 31foot sailing boat, so it is possible in smaller boats too

They say that a J-Boat 92 will plane behind it's asymmetrical spinnaker...

I'm confused...How did we get from boats to planes?

 Oddly enough I was not surprised by this progression

Cool boat John

I don't really have a sailing bucket list. It wouldn't in the normal course of events be achievable.
I do have 'pipe dreams' though. I put them on the computer as my wallpaper to inspire wanderings of the imagination.

This is the current one.

[Sheepdog]

Same with be, John. I've come to realize that a large boat owns a sailor; not the other way round.  As a young guy, I crewed for folks who owned nice sailing yachts, but never had so much as a dinghy, myself. It is a singular experience, to be sure: to be on the open blue water. I still jump at the chance to crew whenever I'm asked...

[Gliderjohn]

Back in the 80s we did a Windjammer Cruise on a four mast schooner that was over 200' in length. As each sail went up you could feel the acceleration. Had difficulty sleeping however as there is no steady noise, but a lot of creaking and moaning. Fun cruise though with great people.

Beautiful boat.

I agree. Very pretty.

I love sailing vessels.

So dang windy here this morning in Sugar Land, TEXAS.  Could of put a sail on the Triumph and turned off the engine.

Those J class boats are just magnificent. Perhaps the ultimate meter boat. (and hugely expensive) Their mainsail was/is the largest sail on any sailing vessel ever. It was sometimes measured in parts of an acre! (as opposed to sq feet)  Any chance you can fulfill that aim Tris?

I think I would be too scared of the AC foilers. I get the impression that you would be an athlete with training and skills akin to that of a fighter pilot to manage those.

MG Pilot, I gather you no longer have that pretty boat. I would be interested to know what induced you to part with it.

[Shorty]

I enjoyed this. I'd never have the stones to do it:  https://youtu.be/28TAdDu5L6U

That's such a great picture.

Years ago at Newport News I got to pilot a 12 meter replica of an Americas Cup racer.  Long story short I used to crew in the weekly race league here, and while on vacation we took a ride on the boat.  Chatting with the captain and he asks if I'd like the helm for a bit!  Sure! OK!  Turned out to be about 30 minutes including a tack or two.  Un-flipping-believable!

Cool thread. My wife and I live on our 36 foot Pearson ketch, and have for over 20 years.

Our best speed for 24 hours was 203 miles coming back from Bermuda. It was a fun trip home.


Here's Rocinante resting peacefully on the hook in Down East Maine.

If those are nautical miles that's an average speed of nearly 8.5 knots. 
Pretty good for 36' I reckon. I bet it was fun!

Neat boats. If I remember correctly, they were an L. Francis Herreshoff design built at the Lawley yard in Dorchester (south side of Boston). I'm north of Boston where L. Francis lived. How did a Yankee make it all the way out to where you live?? You certainly are correct- they were very lightly built.

John- thanks for the pic. That is  a mighty fine looking schooner. Asa  matter of fact, the shape of the stem and trail boards look like the design emulates the L Francis clipper bows.

 John , can not for the life of me remember where I read it , but my earlier comment about "making a day" had something to do with 200 nautical miles in 24 hrs , average of 8.3 knots . At least that feels right , old age and all

Well it's not a term I've come across at all Dusty.  However distance traveled over a 24 hour period is an oft used measure of progress when on any kind of multi day trip.

Our schooner at the beginning of this thread, given it's rather arbitrary water line length of 100' (we don't actually know what it is) should in theory be able to cover 312 nautical miles in 24 hours (that's 360 land miles) but would have to be flat out for the whole 24 hours to do it. An unlikely happenstance in the real world.
