Kids, if you don't stop fighting you will have to go to your room without supper.

My plan was to have a larger sail. Given my size and the usual lack of wind in our area I thought a larger sail would be best. When I windsurf, I will normally use an 11 meter sail when everyone else is using an 8. I use an 8 when the usual sail size is a 6. Will using a larger sail negatively affect my sailing in a landyacht? I think the sail I cut will be about 5 square meters.

Well TPI that just goes to show how much respect you have for me!!
Here I am being exceptionally nice to you, doing my level best to not be insulting etc, etc, blah blah.. Now you go telling people to let me die.. That just plain is nasty..
Ron

I am sorry LY you are right again!
I will go to Nikrums page and ignore him there

I concur. At least a 5 sq mtr sail and you can always put in some extra eyelets to reef it if you need it in windy coditions. Depending on where your first batten is, you could put your reef point just under it.

I have no idea what you just said, could you explain? (Actually I know exactly what you said, I just don't understand what you said.)

I just spent a couple of nights fixing my fiberglass. When I tightend the nuts I got some cracking. Opps. I had glass over my metal bars and the compression caused the fractures. Easy to fix, but a pain in the butt.

I put a brake in place. I will be sailing in parking lots, and everyone here has absolutely no experience. I need something to prevent slow speed collisions with parked cars. With even a scratch costing over $2000 to fix ....

I am using a drag brake that goes near the center. I have attached a chunk of old tire to act as a brake pad. The brake lever gives me a 3:1 mechnical advantage. I looks like it will work. Do you think the lever position will be a problem?






Again, thanks for your help.

WHOA! Dude! You taking a bath?? That does look good. Shoot it doesn't take you long to do 5 minutes work, do it??
I have been thinking about your Logo idea. being as Paul doesn't want his name on it you could change it a "A Sabydent Build" or Just have "Lake Lefroy Mini" But what ever it certainly looks the Part.
I am using the top section of an Ignition Mast and it is fine. Depending on your Sail Foot length you may have to take some off the Head End.

Reefing(shortening) a sail allows you to control the amount of sail area exposed to the wind, so that on strong wind days you can use a reefed(shortened) sail and still have a controlable landyacht less prone to tipping, and on light wind days more power to propel your landyacht. comprendez

In my experience the best "brake" for a speeding land yacht is to steer it suddenly into the wind.

However that is dependant on the surface on which it is being sailed and the area available.

That is a radical adjustment to the dynamic and may result in unexpected motion.

I did it once in a blokart when I had cranked it up to about 50 kmh headed for a solid fence. This is the location.



The result was that I washed off a third of the speed and reversed the facing direction with the yacht passing backwards through one of the gaps in the fence in the pic and my head bouncing off the end of one of the horizontal components of the fence.

As my head was not protected by a helmet, I did see some stars, but managed to maintain my consciousness and composure even though there was some letting of blood.

For a fun yacht I do not see much advantage with the fitting of a brake. Independent rear wheel brakes can provide an advantage to racing yachts when rounding a mark.

Each to his or her own but certainly where you have fitted the brake and where it has an effect is quite brilliant sabydent.

I do think your brake is better than having a brake on the front wheel. Well done mate.

That is shortening the height of the sail by raising the foot. Fold/Reef the bottom of the sail against the boom and Tie it off through the eyelets. Talk to your Sail Maker he'll know exactly what is being said.

Somewhere in these pages there is a formula for Mast Construction and I believe it is best to stick to that or see if you can dig up a disused Mast as I did. you'd be surprised at what people have stashed away in their sheds.

If you can't find it then I will have to dig up a copy of the layout and send it to you.
Ron

Now there is a Q I can't really help you with. I don't understand the last part of the Q but generally speaking common sense should prevail. If you are lucky Paul might step in a give you more. Keep in mind that I am using 100% DF Masts. I don't think there was any Welding on the Mast construction just various lengths of different Calibers of Ali Tube.
Did you find the MAst Construction Pages??

That is a strange looking sail Paul, how does it go.

How about some pics of the new mini

Okay I get reefing. Now, about the mast. Is the 34mm tube with 4mm walls okay?

Brian

opps should have said about the boom.

theres not alot of pics or bits yet. the domestic gods are on my tail, then I had this silly idea about miniminis.
that sail is the one i used last year, and josephine got her 105.at easter in the 3m reefed set up I was doing just a bit slower than wayne , who was fastest for the weekend, but the material is getting stretchy and doing some skitterish things at speed. I plan to step back to my original 4m foxtrot sail shape and start again.

Go back to the LLF mini build thread All your boom questions are answered
there with pictures as posted by the Guru himself

Okay Harleyd:

My paint is done except for the wheels, just have to make the boom, which is happening tonight. Busy until the weekend... finished photos to be posted on Saturday or Sunday.
