Your Favorite Hull Designs for Monohull Sailboats

[Steadman Uhlich]

I am starting this ongoing thread in order to share some images of hull designs or shapes we sailors admire for Monohull Sailboats.

You are encouraged to participate, and to contribute to this thread. Post your favorite monohull hull designs or shapes (drawing or photo) to add to the mix and discussion.

If possible, please post a photo or drawing that shows the profile of the boat's hull, including her full hull or down to the keel. If you know the particular dimensions of the boat (LOA, Keel Depth) please add that too.

Please add some anecdote or comment about what appeals to you in this design. If you have sailed on this type of boat, mention that and what you remember from your time on the boat. If you know of strengths and/or weaknesses of this particular design, mention that too.

The hull shape can be shown as a photo of a boat (on the hard, in slings, on stands) or in a drawing or plan or design of the boat.

The boat may be a cruising boat or a race boat or daysail boat or any monohull sailboat. It may be a classic, or the latest in cutting edge technology. This is not a contest, so any kind of monohull can participate.

The point of the thread is simply to share and discuss what we like or admire and to discuss the qualities or characteristics of those hulls. Some may simply be posted because they are visually appealing (eye candy or "boat porn").

I hope you have fun sailing and on the forum too, and I hope you enjoy this thread as it develops.

I am starting this with a photo I saw today of Endeavour being lifted by three cranes. Endeavour is famous as a classic "J" Class boat that was built for racing in the America's Cup Race in its early years. She is a very large boat, that has been resurrected (by Elizabeth Meyers) and sails again in regattas and races other J Class boats around the world. Scuttlebut says she is now up for sale again. I have long admired her beauty, and at one time had a large wooden ship model of her in my house.

Hi Steady Hand, first I would like to apologise in advance for jumping in on your thread, but could you please tell me how I can upload some photos on a posting I would like to make here. Many thanks.

That is a good question. No problem. I hope what I wrote below helps you and others to post more photos to illustrate threads.

How to post a photo or multiple photos on CF threads:

I encourage everyone to post photos in CF because everyone enjoys seeing photos of boats and photos of gear helps to clarify communications about problems and helps others help one another with answers that fit questions. When you post a comment, you can use the "Post Reply / Advanced / Manage Attachments" function to add up to 12 photos to your post. It first allows 6 photos, but if you upload six first, you can then add another 6 for a total of 12, if you want, all embedded in a single post, and all uploaded at one editing time.

Warning!
Be careful not to take too long to upload and edit your posts, as the forum software "times out" after a few minutes (and no one knows how long that is, but I suspect about 5-10 minutes), and all that writing effort can be lost. This is a common problem for members who write detailed or long posts.

Safest Method for Long Posts
If your post will be long or complex, or involve original writing, it is a smart idea to write your post on a text document using an off-forum text editor, then when you are finished writing it, copy and paste that Long text block into a new post. This is safer. I know, because I have lost original writing efforts due to the forum software timing out on me, causing a total loss of effort. This has happened to other CF Members too. So, if your post is long, or detailed, or complex, or important original writing, then make sure you write it off the forum first. That is what I do, after learning the hard way.
-----------------------

You can find a very easy to follow video instruction about how to post photos on CF by going to the FAQ here or look on YouTube for a very clear video that shows how to do it. It is easy, but not intuitive. The video is a big help. Here is a link to the video.
https://youtu.be/NW5n8vZM34c

Watch and it is very easy to do. You can also post other types of content (videos, etc.) and photo files of many kinds.

Speedy Tip 1:
I usually post a jpg photo file that is about 1200x800 pixels, because that is what I consider a nice large size for web viewing. Most files can be downsized to about 100kb - 400kb or some larger. If my original photo file is high resolution (like a photo I take with my iPad), I prefer to first use some software (an app) to downsize the image file so that it is smaller and faster to upload. Since I use my iPad for most of my web surfing and CF surfing too, I use a free app called "Image Size" (by www.vsmedia.de) which is very easy, fast, and has multiple options. It does have some ads in the free version, but $1.99 removes the ads. I have no connection to that app other than being a happy user. It works for me and is intuitive and flexible.

Speedy Tip 2:
If you think you might refer to that photo in the future (e.g. Photos of your own boat or boat projects or gear), you could also upload it to your CF Profile and start a photo album there to contain your boat photos.

Speedy Tip 3:
Some people will upload photos to their own blog or website or a photo hosting site, and then use that photo or want to embed that photo in a post. Since I do most of my surfing from my iPad, I simply copy a photo and save it to my iPad, then upload it to my posts from my iPad, or Mac if I am using it instead. In other words, I temporarily have the photo on my iPad, and then after I upload it in my post I delete it from my iPad.

_________________

Here is another method recommended by one of the CF mods:

1. upload the image you want to attach to an online service or your own website or blog.
2. use the "insert image" tool and enter the url of the image you have uploaded.

3. Conversely, if the image is on an existing website, right click on the image and select copy image location url or similar wording, and again enter it into the image tool field.

Here is a topic on CF with the video embedded.

Dear Mr Steady Hand,
I think you need look no farther than this hull... 150 years odd in the making..

Hello from Sunny Cornwall by the way ....

[Delancey]

Did some inland lake sailing in my youth. Always thought scows were sort of interesting. When heeled you end up with a very multihullesque waterline length to beam fineness ratio. Very long and skinny.

Class A Scows pictured. 550 sq ft sail area on a 38 waterline length with an 1,800 lbs. displacement. Go go go!!!!

[SpiritBear]

I grew up west of Minneapolis and we had all classes of scows on Lake Minnetonka. I actually saw one adventurous soul try to water ski behind an A-boat in a good breeze (yes, it's entirely possible). Problem with an A-boat is that you need to find at least a half-dozen friends to come along as ballast. :-)

Some facts about Endeavour from the Wikipedia article:

Steel hull.

Displacement 143 tons
Length 129 ft 6 in (39.47 m) (LOA)
88 ft 2 in (26.87 m) (LWL)
Beam 22 ft (6.71 m)
Draft 14 ft 9 in (4.50 m)
Sail area 7,651 sq ft (710.8 m2)

Now with carbon fiber mast.

Original 1934 specs:
Crew 31
Hull Steel
Mast Steel
L.O.A 39.53
L.W.L 25.6
Mast 46.47
Beam 6.7
Boom 18.95
Sail Area
Displacament 223.1
Draft 4.57


"Endeavour is a 130-foot (40 m) J-class yacht built for the 1934 America's Cup by Camper and Nicholson in Gosport, England. She was built for Thomas Sopwith who used his aviation design expertise to ensure the yacht was the most advanced of its day with a steel hull and mast. She was launched in 1934 and won many races in her first season including against the J's Velsheda and Shamrock V. She failed in her America's Cup challenge against the American defender Rainbow but came closer to lifting the cup than any other until Australia II succeeded in 1983."

Here is some interesting history of Endeavour after the 1934 Americas Cup. I am including a photo below that shows her as a hulk before she was restored to beauty.

"Following the America's Cup, she dominated the British sailing scene until, whilst being towed across the Atlantic to Britain in September 1937, she broke loose from her tow and was feared lost.[2] the hulk was eventually found and returned to England where she was laid up. For 46 years Endeavour languished through a variety of owners. In 1947, she was sold for scrap, saved only a few hours before her demolition was due. In the 1970s she sank in the River Medina, Isle of Wight. Endeavour was purchased for ten pounds and patched up enough to refloat. Until the mid-1980s she was on shore at Calshot Spit, an ex-seaplane base on the edge of the New Forest, Southern England. By this time she was in a desperate state, with only the hull remaining, lacking rudder, mast and keel."

Foiling is not just for multihulls. In fact, Moths dinghies were early adopters long before the AC.

+30 knots anyone? Easy peasy.

[Delancey]

Then of course at the other end of the development platform spectrum you have the Open 60 class. Wide beam, twin rudders, chines, canting keels, daggerboards, foils....

[Steadman Uhlich]

To DELANCEY:
Thanks for adding to mix!
The foiling Moths are indeed special.
And I have always admired the scows too.
Interesting boats optimized for speed.

Here is a photo of "Ranger" on the hard. Another J Class boat.

Hello from Sunny Cornwall by the way ....

Hi TIGGERTOO, I posted the photo for you. To do so, I clicked "post Reply" button, then the "yellow square with mountain" button on CF (above the text entry box) to make the image post, and deleted the http: from the pop up dialog box, then pasted the URL for your photo, which already had the http: in it. Hope that helps.

Dragon (International Class)

Steady's Notes:
This is one of the boat designs that never fails to make me stop to admire them, with the immediate wish I could sail on one. They look so beautiful to me, especially when made in wood.

This boat was featured as one of the boats used in the 1948 Olympics.

Here is some info on the design:

Hull Type: Fin Keel Rig Type: Fractional Sloop
LOA: 29.17' / 8.89m LWL: 19.00' / 5.79m
Beam: 6.42' / 1.96m Listed SA: 286 ft2 / 26.57 m2
Draft (max.) 3.92' / 1.19m Draft (min.)
Displacement: 3740 lbs./ 1696 kgs. Ballast: 2200 lbs. / 998 kgs.
Sail Area/Disp.1: 19.04 Bal./Disp.: 58.84% Disp./Len.: 243.42
Designer: Johann Anker
Builder:
Construction: Wood or FG Bal. type:
First Built: 1928 Last Built:

From Sailboatdata.com:
"Following a competition organised by the Royal Yacht Club of Gothenburg, the Dragon was conceived as a "day boat" or small coastal cruising boat. Selected as the 3 man keelboat for the 1948 Olympic Games in London.
The designer, Johann Anker was killed in World War II. After the war, his sons waived the royalty for the design to English builders as a token of appreciation to that nations support of Norway in it's darkest hour.
Although it's Olympic class status ended in 1972, it has remained popular around the world in to the 21st century."

Here is a link to the class website for more info and current or recent events for the class: http://www.intdragon.net/mobile_home.php

Here is a link to one currently for sale on Yachtworld. It was built in 1938, in wood, located in Ireland. There are many photos on the ad, so you can see the boat inside and out. Asking price = $29K
