Force 7 Ocean Wave

Yes

The rudders are very small (from an aeronautical point of view) because in this tradition there is a belief that a 10-ton yacht is a miniature super Oil Tanker.

A ship's rudder is simply an alarm clock to get Mr. Max Michael Munk out of bed and to work.

What matters to a 100,000-ton ship is maneuvering.

What matters to a 1-ton windsurfer (and could also matter to a 10-ton yacht) is the stability of the balance on the yaw axis.

What has happened (1970-) is that the following has been added:

1) a tradition based on big ships.

2) races (1970-) were won on a windward course, and agility in tacking was essential.

3) before (ca. 1930), yachts were anchored, and now they have to maneuver in narrow harbors.

4) inertia.

5) imitating racing yachts, a problem that already appears in the vorword to the first edition (1904) (!) of the Skene elements, which for more humor already predicts the inevitability of the Scow form that we see triumph in the Mini Transat (2015-)

 

Peter Bruce, Heavy Weather Sailing

Monohull tactics

"Such crews will have 6 or 8 racing experts sharing the helm duties"

(!?)*

6) A tradition of wooden ships and iron men.

This is exactly the yachting world that I knew, my idea is certainly revolutionary: a sailboat for 1 (that doesn't need 6-8 expert helmsmen and a cook) and designed for enjoyment

*: "That's why most cruising yachts shouldn't sail downwind in heavy weather"

and we come to the dead end that I have known since the last century: on the one hand, modern yachts (1970-) cannot be left still in bad weather and, on the other hand, they are not capable of surfing safely.

That's why i want (A) a type MiniTransat windsurf board much more comfortable and safe that a MiniTransat ... that (B) by the rudders out of the water, can withstand a storm, bow to the waves with a sea anchor like a Ocean Row Boat

Instead of neither nor, and and

the peace of mind of a well-adapted, capable machine



1 Ton movable Ballast on a Billonaire SailBoat

 

In a 1-ton boat (Ocean Capable Dinghy) for 1 crew, we do not have at our disposal either the Billionaire solution or the Dinghy solution:

 

This is a bit crazy solution

 

L_CF: 58%
L_CB: 60%
L_CG: 62% (!)

From my point of view, it is more beautiful to have a hydroStatic worthy of a 1930s British classic ... along with well-thought-out hydroDynamic trim.

A 1-ton convertible sports machine

It is a tradition that considers discomfort and even suffering normal.

Currently in Europe, a 20-square-meter per Ton sports sailboat costs 180-200 K.

When I see a Mercedes without seats, I'll look again at the catalogs of this industry.

Small, compact

1) The square-cube law plays in our favor.

2) It has to navigate over a variable field of dynamic pressures: the sea.

Consider a vertical dynamic pressure peak measuring 5 x 5 meters: the entire boat rises, whereas on a 15-meter yacht, that vertical dynamic pressure peak may only act on the stern. Thus, we are repeatedly surprised by the magnificent behavior of tiny boats like aerial dancers.

3) On the other hand, there is the issue of the wave's orbital current and countercurrent.

Gennaker: 24 sqm
Jib: 9
StaySail: 7
MainSail: 14 sqm

A cockpit that's a real cockpit

means comfort, a pleasant feeling of being protected, and very real safety in a tiny boat.

the sailor is close to the center of gravity, avoiding the violent movements that can be felt aft, especially upwind.

Speed, speed to create comfort. Movements in a tiny boat can be very, very violent. Many fantasize about sailing slowly and pleasantly. The reality is that speed stabilizes a sailboat greatly.

The logic behind a dinghy, a real Dinghy: you don't step on the deck.

There are no stainless steel fittings or cables on the deck.

The StaySail, thanks to a boom, has one reef.

The mast is about 50 cm from the cockpit.

The bowsprit pivots aft. Of course, the sailor has to lift their butt off the seat. Cruelty on the part of the designer.

(I know I'm repeating the same joke over and over again)

A sailboat to enjoy. You're completely crazy. What's next? Adding a motor? You're ruining our glorious tradition of wooden boats and iron men.

Pogo 1

The small, light and sporty sailboat has great potential, it just needs to be civilized a little.

 

You could at least build a working model.

 

Haha

The world is upside down.

Let the troglodytes who place three tons of lead 1 meter from the Pitch axis of rotation ... and don't bother to calculate the rudder make a working model.

Atlantic, Force 7:





Make a working model to put a fuxxx seat with a backrest on a fucxx boat and put the centers (Center of Flotation, Center of Buoyancy, Center of Gravity, hydroDynamic Center of the Keel) together. Haha
