New Jib Design Idea

Put more clearly

Small (=< 1 Ton) sailboats are a marvel

1) They can carry wonderful rigs: simple, comfortable, versatile and efficient. And a sailboat is first and foremost its rig

2) They easily hoist a huge amount of sail: 20-30 square meters per ton without spinnaker

3) They tend to behave well hydrodynamically among other reasons because they are in the same part of the wave

4) You can lift the propeller of a 2-horsepower outboard out of the water, you can steer it to maneuver, you can lift the centerboard and rudder blades out of the water to keep them clean and to land on a sandbank, and they are not the maintenance nightmare of larger sailboats, they leave you free

 

What is missing from a small 1 Ton boat to be a complete and absolute marvel

Answer

A) magnificent passive safety
B) the active safety of being able to surf big waves, and
C) the upwind capacity to leave it stationary to avoid damage and to rest the equipment and the crew, that is: to anchor in the sea bow to the waves

 

We know from our own experience and from the experience of others that in a gale or a storm no one changes course, we cannot demand a rare psychological strength

I think a small sailboat must have the ability Downwind to surf very well and on the other hand Upwind the ability to ride the waves head on

 

What can we do with a Dinosaur

1) be sad about Downwind because the rig leaves us with 5-7 effective square meters per Ton and the alternatives are as horrible as placing a sail on each side and placing the wind right on the stern, completely absurd even seen from the 19th century

2) repair the Dinosaur in exotic places or wait for spare parts in exotic places

3) call a helicopter in a storm because the European category A sailboat is neither capable of surfing nor is capable of staying still safely and the owner's manual keeps secret what to do.

European Category B sailboat, capable of Force 8

how?

Silence, silence, it's top secret

 

- You don't want a Dinosaur, well, well, this our glorious industry offers you a nice light sailboat

 

It's quite rare to see a fractional mast break above the hounds - in fact these days breakages are far rairer than a few decades ago in racing boats.

The masthead rig doesn't seem to be very popular among new boats. But personally I'd say it's still a great rig for many sailors who are doing longer passages, where you don't need the same sort of swift flexibility of tune to different condtions and angles or the easier tacking with the small headsails.

Just IMHO but one of the fractional's strong points is that it depowers by flattening the sails rather than reducing area. That's great when the boat is sailing at the right (quite fine) angle of attack - but even when the sail is flattened and depowered there is still more physical area up there than in a masthead rig where you reduce area rather than flatten the sails.

If you're not steering or trimming fairly carefully to remain in the groove, and you end up at a broader angle of attack, then the fractional rig is effectively no longer flattened, and it quickly becomes overpowered. So IMHO the fractional rig is in some ways more technically demanding than the masthead rig, where ending up over-sheeted or pointing too low isn't such a drama because you have reduced area more. Secondly, getting the best out of the fractional's ability requires sails that can be flattened out effectively, unlike the typical roller furling headsail.

 

Complete and utter rubbish that either shows deep ignorance or is an outright lie, and may lead the gullible into danger.

Bearing away over crests is a standard technique for ocean racing sailors in heavy conditions, up to storm force. For example, see the quote in "Heavy Weather Sailing", one of the classic books in the sport. On p 157 Ed Psaltis is quoted as saying that one can "steer through big and confused seas. It is possible to position the yacht best for each wave as it comes, or steer around it".

The book also notes the experience of people like Andy Cassell in the light J/30 in the 1979 Fastnet, who are trying lying head to wind and running, went broad reaching and "listen(ing) for the breaking waves and lin(ing) up the hull in order to surf down at an angle" with success. In the same storm, the Australian Admiral's Cup team members all kept sail on, fore-reached, and used their speed to get around the waves.

Claiming that we know that people cannot change course in a gale or storm is a dangerous untruth borne of ignorance or dishonesty. People can and do, and often it seems to be the best tactic. If you are unable to do it I am not surprised, but that does not mean that we cannot do it.

 

Here is the Mini

The spreaders are very small

 

a Mainsail worthy of its name

(This photo does not match the previous one and the spreaders have been changed and are larger)

 

All we have to do is

a) increase the freeboard from a ridiculous 0.65 cm to 1.05 m, and reduce the monstrous beam to 2.5 meters, so it stops being shaped like a turtle or omelette and with moderate proportions we get very good passive safety by adding a good deep lead ballast

b) we center the mast and place it near the cockpit and near the hands of the navigator who never leaves the cockpit

c) the rudder blades can be taken out of the water, so they are safer, they stay clean, and allow the small boat to first hove-to like a Yawl and then if the waves get bigger it can anchor in the sea head-on to the waves like an ocean rowing boat without breaking the rudders and without making violent yawings

 

And to make it a delicious magic carpet with great pitch and yaw control we do like "Aqua Quorum" which showed its good behaviour both Upwind and Downwind in the demolition derby of the Vendee Globe 1997

d) we move the keel towards the stern, which actually means Centering it by reconciling the center of Buoyancy with the center of Flotation

 

This is a Sail boat

Joshua Slocum on his old 19th century barge set the wind "two points" from the stern

I think it would be logical that in the 21st century on a modern sloop we would set the wind "four points" from the stern

---

I think it is quite reasonable to design for

45 degrees of true wind angle (TWA) relative to the bow Upwind, and

45 degrees of apparent wind angle (AWA) relative to the stern Downwind

 

haha, i hadn't realized: "French omelette", "tortilla francesa"

Plywood Epoxy MiniTransat

The sailor sails comfortably seated on a Persian invention called a cushion that protects his bottom, a huge backrest that is both comfortable and safe, he is tied with a harness, and the beautiful Mainsail is controlled by mainsheet, boom vang and preventer, 3 in 1, three ropes in a single rope thanks to a carriage that runs on a huge rail from side to side
