New Jib Design Idea

[gonzo]

Let's get back to the thread about a jib idea. CarlosK2 you can start a thread on beaches.


A bipod rig has been tried and is not the most efficient for sailing. It may have some other appeal or particular uses though. However, as far as influence on the jib, it may be no difference.

Redefining Cruising

I think the small one-man workboats, Itchen Ferry and Falmouth Qay Punt, and the minimalist Dinghy Cruising are the good roots and good sources of inspiration, and not the Victorian yacht whose smallest (ca. 1890) carried 6 crew

A small, comfortable and safe sports machine, an efficient "mountain bike" (But not the Yrvind sarcophagus for a Fakir) can serve the more adventurous to go to the Azores, Cape Verde or the Hebrides in Scotland or go to the Caribbean, and for the less adventurous it would be a magnificent coastal sailing boat

Right now (2025) this industry promotes the sailboat to planing

I am not interested in planing, I am not interested in speed on flat terrain, what interests me is comfort and functional pleasure

the functional pleasure of a comfortable, versatile and efficient Rig

the functional pleasure of a sailboat capable of 5 knots beating 25-30 knots of wind Upwind

the functional pleasure of a good surfboard that with correct Longitudinal Balance (LCG > LCB > LCF) astronomical Longitudinal metacentric height (3 x LWL) and magnificent control of Yaw can sail at 10-14-16-18 knots propulse by the Waves that are sons and daughters of the Wind and the powerful Force of the Earth

That's fine. Start your own thread. Hijacking other member's thread is rude and inconsiderate.

"propulse" (?)

propelled

Yes, propelled, driven

"The turbines propel (or: drive) the plane"

"The ease with which the classic models surfed and the control [of Surf] was a big surprise

(...)

Modern designs suffer because the wave that hits them lifts the stern and sinks the bow thus creating a big Yaw moment of of the Hull"

(Andrew Claughton, Southampton, Wave Tank)

Funny how old heavy 300 D/L sailboats Surf wonderfully

Time and again both with Wave Tank models and in the real world it is empirically proven that Old Heavy Classics surf wonderfully

For planing the right thing is 100 D/L (and 30-40 sqm per Ton) and at least 150 D/L and 30-40 sqm per Ton

But for Surfing the question is

(1) control of Pitch
(2) control of Yaw, and
(3) good Hull Attitude for Surfing: stern down; bow up

Surfing is the way

For crossing an Ocean with a big or small, heavy or light, sail or motor boat ...

Surfing is the way

Hello! I came up with this idea to minimize the air influence from single mast on the main sail.

the idea mainly came from reading this paper. I came up with an idea of an A-type that is basically the best of most worlds, in which its still as convenient as the standart and as performative as a foil-sail. Given that i recently found a guy who can work with carbon fibre at a high level, the goal is to make it in the same weight category as a standart single big mast.

What do you guys think, will it work?

Are you still around? Send me a message.

the Victorian yacht whose smallest (ca. 1890) carried 6 crew

I'm curious. You have already seen real photos proving that this bizarre claim is utterly wrong. The simple undeniable reality of history is that there were singlehanders, doublehanders and triple-handed boats in Victorian times.

Below are Victorian yachts c 1890, with one, two or three crew.

The William Fife (III) designed Dublin Bay Cutter, Vagrant. Vagrant was acquired by the Scottish Maritime Museum in 1985 and is scheduled to undergo restoration in 2011/2012. https://www.flickr.com/photos/scottishmaritimemuseum/4856510725

The bottom pic, from WP Stephens, is repeated in the wonderful Earwegoagin blog along with plans of other small and singlehanded cruisers from the Victorian age.

Your statement is completely untrue, full proof has been given to you, and any further repeat of the claim would be nothing but a bald-faced, unashamed Goebbels-like lie of the sort any human should be ashamed to make.
