New Age Trawler/Motorsailer; Kite assisted PowerYacht

[Hacklebellyfin]

Hi,

I hope you are all doing well.

I joined this forum because i felt in love with the idea of sailing a boat with a kite.

Now I do have some questions about Kite boating:

ferrocement (concrete is so cheap )+ kite?

Multihull +kite?

Indonesian pinisi+kite?

What is wrong with the winch as seen in this hawaiIan tv news Video?:


What do you think about Stephanie Krucke design?:

If you can find an easy way to do the control and handle the kite then the kite is an option.

Would be a real pleasure not having to worry about masts and stay's...

I'm sketching out an alternative design, involving a Harken traveller car and track. In a nutshell, the kite control bar is mounted to the car, and then there are "tiller lines" running to a steering wheel in the cockpit. Steering the boat is with rudder pedals, perhaps a whipstaff. With my current thinking running toward a catamaran or tri with a small center hull, I realized it's entirely possible to cruise with the leeward hull flying! How cool would that be?

You still have to ACTIVELY fly the kite.....

automatic winch:

mechanic:
rotative base >hydraulic
short mast>hydraulic

Electricity:
hydraulic compressor> solar panels

Navigation
electronic weather cocks
connected to
laser scanning the wind window, positioning the kite on computer and sending orders to hydraulics...


Better:

A level ruler fixed to the kite rig, tuned to best angle.

When bubbles reach an end of their own tubes where sensors are fixed
it sends impulsions trough a wire fixed along the rope down to the computer that gives order to hydraulics.

automatic winch: = lotsamoney

mechanic: = lotsamoney

Electricity: = lotsamoney

Navigation = Too complex & even more money

I can understand why a cargo ship might try a kite to reduce fuel consumption a few percent , but why would someone pass up on a genuine motor sailor , with known abilities far superior to a kite ?

Simply the extra volume of a big trawler box of a boat , or the claimed extra work of a boat that genuinely sails?

Hi Fred,

There could be a few advantages to a kite, my opinion.

No mast, no stays, no rigging,
-and so less structural compensation required.
May not be as limited in size.
Can fly high, in better wind than on the water surface.
Single control unit.
Should be able to fly to windward as well as any sail.
Has a lifting effect on the vessel, heeling over may become less of a problem.

If a sensable way to launch and retreive and fly the kite can be found then most of the problems are solved. Such a setup may well be less costly than the conventional sail setup too.

Yep, there COULD be advantages, but the product is not fully able to be applied to smaller recreational boats YET....

[Hacklebellyfin]

Thanks Fanie.

And isn't our duty to share infos , open new views ??

Am i born a hundred years too early?

Any constructive comments to get that kiteboating for small vessels thread going in the right way?

Since we are boys, we can play with toys. Nice challenge to get it figured and tried out eh

And isn't our duty to share infos , open new views ??

No, whatever is shared is out of free will. There is such a thing as intellectual property.

Am i born a hundred years too early?

I don't know. What does your mother say ?

Any constructive comments to get that kiteboating for small vessels thread going in the right way?

Who knows. If we can get the available resources ie hydrogen or nuclear propulsion right we would probably give the kites back to school children to play with.

Yes you do. And in a... "mastboat", I guess, let me just coin the term here and now LOL... you still have to trim the sails. Oh sure ;in the trades if you're not looking to get that last 1/10th of a knot out of her you might leave the sails alone for hours (or even days); but honestly, in a daysailer, on a pleasant afternoon, how much fiddling with the sail/sheet/boom/bowsprout will you do? Isn't part of the fun pulling on all the strings?

And can I suggest a decent harness to keep your ugly bum from being plucked off the boat

Mmmm... I just had a not her one of my brr-ain waves. Since the kites in the pictures have a control pod to make it look more complicated, you can use the same kite to catch fish with.
Here's how -
Get the kite up
Get hooked into a big one
Attach kite to line.
Fight fish with kite via rf link to pod
Fish tired, fly kite to boat.
Send wife to get fish aboard so she can clean and cook it
You pour a stiff one to get in the mood for dinner / supper / whatever.

If you lose a fish you can always blame the software

Oh damn, you don't need a boat to fish this way At least the city yappies can also fish now without getting too physical

[masalai]

Sorry Fanie, but it is already being done, the problem is waiting for an offshore breeze to take the lure/baited hook offshore. In a similar situation, use CHEAP party baloons to carry the baited hook/lure a suitable distance offshore.

If you are boating and wish to troll the lure closer to a reef edge than you are willing to run in your boat then attach a short plank with weights to keep it vertical and a little "hand flag" mounted for visibility and tied back to a point so the plank tracks off to one side.... (do you need a diagram?)

[Fanie]

Yes pleas Mas. A detailed drawing should help.

We actually use another technique in such situations. It's called casting
