New Jib Design Idea

[gonzo]

The biggest problem i see is communication with the sailmaker

(It has been known for a long time that human communication is almost impossible since communication is born to transmit emotions and is an elaborate variation of the shout)

They are very used to full battens on flexible masts with back stay, and less used to the idea of a very firm mast without back stay

Maybe a sailmaker in touch with his feeling would be able to make you a perfect sail. However, this is another of your ridiculous statements. It is typical of people with no experience but lots of arrogance.

 

[gonzo]

The problem is that you give a professional athlete a machine that does a tenth of a knot more upwind (or one knot more downwind) and no one can beat him.

It is not a problem. It is racing. We would be ecstatic if a tenth of a knot of extra speed could be achieved. One hundreth is more than enough to win a race.

Plywood Epoxy MiniTransat

Cruiser Version for an old fogey or a young adventurer

completely orthodox and traditional, and functional as a work boat from 1860

Jib
StaySail
MainSail

the mast is 50 cm from the cockpit, a small detail but of enormous importance, I remember the story of a kid who fell from the bow of a MiniTransat and was left hanging by the harness while the bow of the fast sailboat tried to drown him

StaySail with boom without up and down movement allows what they now call "3D trim": twist, camber and angle of attack Upwind: 7-10-14-20

and allows large angles, 30-45, for Downwind and

allows installing a reef to reduce the size of the sail and turn it into a sail for surfing in a big storm if that were the inevitable case or sought by a young and adventurous athlete

and bowsprit, a carbon fiber tube taken from the mast of a windsurf board, that turns towards the stern to enter a port and to reach the hands of the sailor

NS 14 heigh: 5.5 m
PEMfaOFoaYA: 8.8 m

Mode "old fogey"

1.05 Tons
137 D/L
28 sqm per Ton

Mode "young adventurer"

1.25 Tons
164 D/L
24 sqm per Ton

Considering that the bowsprit turns towards the stern reaching the hands of the sailor, the young adventurer with total comfort and safety from the cockpit could hoist a 30 square meter Jib/gennaker and thus the machine would be propelled by

40 sqm per Ton

 

[CarlosK2]

By comparison

The typical Dinosaur Downwind is left with about 7 square meters of effective Sail per Ton because it is impossible to orient the genoa well, and placing a sail on each side only achieves 10 square meters per Ton and invites Roll to create a very ugly and quite uncomfortable ride

On the other hand, the light sailboats 110-120 D/L and >300 thousand Euros now in fashion among the wealthy need to hoist a colossal Spinnaker of 140 square meters to reach 30 square meters per Ton

And then you need a crew and a cook like in the time of Queen Victoria

 

[CarlosK2]

If one day

If one day I emerge from my ruin and become a millionaire again, I do not plan to return to the Dinosaurs and much less to the supposedly light sailboats currently in fashion among the wealthy, but to a sporty, light, small

I remember when one of the volunteer and ill-tempered watchmen of this forum said something like - where is that data

then I realized the strange idea these guys have about interaction in an free space

- you want "data", well, give me something, give me money or give me affection or give me a good idea to design a comfortable, efficient and safe sailboat - since you don't give me anything, nothing, why should I give you something, so I give myself over to the solitary vice of soliloquy

I can give you sarcasm.

It is utterly incorrect to claim that others here have "strange ideas about interaction in a free space". This forum is specifically about DISCUSSION. A discussion is an discussion or debate - not a place for soliloquy.

It is utterly incorrect to call others "ill tempered" - we merely object to the foul insults and untruths you throw around. That is being principled, not ill tempered.

Yes, you do engage in a "solitary vice" with your self-praise....

The small boat will sail at 5-6-7-8 knots of speed

A slow sailboat seen from the now fashionable >300 K Euro planing sailboats with gigantic spinnakers

but the 10 knot Wave will take the small boat at 10 knots, the 14 knot Wave will propel it at 14 knots, the 18 knot Wave will propel it at 18 knots, and the 20 knot Wave will take the small boat and magic carpet at 20 knots with total control of Pitch and Yaw and complete harmony with the Ocean Waves

The Keel "reculé" (set back) is completely logical in a modern Sloop

"this feature is paramount for fast downwind sailing in big seas"

E x a c t l y

Because in a modern Sloop with LCF around 57% LWL the Keel "reculé" (set back) is simply in the Center

 

[CarlosK2]

(note the Bowsprit)

When I went bankrupt and stopped sailing in Dinosaurs I discovered the MiniTransat: a large dinghy and a very good sailboat

But they are uncomfortable or very uncomfortable

From my point of view it is possible to design a type MiniTransat, much more comfortable and safer, and it would be an ideal small sailboat, both for the coastal cruise of an old sailor and for ocean adventures

 

[CarlosK2]

I don't know if you have sailed much on modern Dinosaur sailboats (1970-) that is to say I don't know if you understand the laments of 'the poor millionaire': "at home I lived like a king and here in the Caribbean I am the "Hausmeister" (janitor)" a retired German doctor told me

and Downwind on a Dinosaur you have no sails, or the nonsense of inviting Roll sailing with the wind at the stern

and on light planing sailboats they offer you a "French omelette"

I mean that a little good will and knowledge is enough to understand the real problem that I want to solve

 

[CT249]

But you give no one else goodwill - instead you lie and throw abuse, sneers and insults at people with far more knowledge than you have, such as Ron Holland. It is therefore hypocritical of you to ask for good will and knowledge.

I feel sorry for the people who may have trusted you and lost their money when you went bankrupt.
