Class3

so confusing......attractive woman speaking whatever as intro

unatractive male giving sales pitch in unknown lingo

Action... very nice yacht doing its best to fly, with english sign writing

so why wouldnt you build one ?

< that's a yes from the kids!

Hey Thanks for that Paul. Still trying to get the idea out of my head. But you know me.
I am gathering info from all over the place at the moment. If I go ahead I will build a strip body same as my Kayaks I can build it as light fiberglass and to the shape I want.
The timber for the spring boards looked like being a problem Thanks for the offer much appreciated.
Cheers
Vic

That is a good bit of vid ^^^^ seems like a great thing to do here

Cape Keradin >>>> Whallal West Australias best bit of beach

<<<<< "YER Yer Hurrah " says the landyachting Orangatangs

Thanks Paul.
I have email's going every where at the moment. Yes I knew that was a class2 but if I do it I will go class3 with a strip built mast 300mmx 5mt. and get a sail to suit.
The axle are 3.8m x175mmx20mm Three pieces
Spring board 2.5mx175mmx20mm Three pieces.
Would tazzi oak be suitable?
Starting to get keen.

Have you got spy's out Chook.
Yes the idea will not get out of my head so I drew a full size plan of the shape I thought I would like and cut some forms and strips. I am not going to post it it construction yet. Not until I am fully committed. Just something to do at the moment.

happy with the shape so far, may round of the bottom a little more

Thanks Gizmo
Looking at it I think I can round the top a bit more to. There does not appear to be any plans available for these yachts anywhere I have tried Europe,England(Getting some info and Measurements and pic from there)USA and New Zealand(Offered to help but no plans available)
I am flying blind on this one so all advice is welcome
Cheers
Vic
The new airtrack's have fairly high sides

Gees Vic, all this so far and you say you are just thinking about building !!

That bar behind the pilots head is an ideal place to fit a boom traveller. I notice the wheels are fairly upright, is that the way they are going now also?...w

Is this of intrest?
I am trying to find the rest of the plan in my archive

So long as you work very slowly lefroy might have dried out by the time you finish.

This is the original strip plank plug made by Colin Palmer back in the early 1990s.
Note the elliptical cross section.
The mold from that plug has produced many of the top class 3s racing today.
Also my class5 pod is from the rear half of that mold. Thanks Colin.

No Vic, but after getting to know you, a man of your abilities is never idle.
I took an educated guess, that you were on the case.

Wow, I'm impressed already with your design.

What materials is the mast constructed of?

Big yachts have big loads on them, the wheels are probably upright to minimise bearing strain. Talk to any engineer and its well known that bearings are not at their optimum running with a twist in them (like Class5).
Twisted bearings don't survive long if you were running them 24/7 on heavy loaded machinery or a production line.

At one stage I did a lot of work on some machinery that needed to be modified to gimbal bearings for that exact problem.... With fixed bearings the best we would get is 3 months constant use in a high load / high humidity location, I add gimbals, 5 years ago and they are still going strong.

Alfa / Beanshoot tumblers (runs 24/7 for 10 days then harvested, cleaned and reseeded then back into production. A full revolution takes about 10 mins)

I put 2 bulkheads about 12'' apart for and aft in between the mast step. I would run solid wood 1x3.5'' all the way from the bow to the front edge of the fuselage for strength. The CP boats have a vertical plywood web( I ran 2 internal bob stays with turn buckles) that runs under neath the center line of the boat from bow to front of the fuselage. It kind of tapers up from the maststep / feet area to zero where the cockpit opening is. If you build a FISLY 3 a spring board is not needed because they are too short. This boat is nice and thick = strong up front and probably easier to make than a CP type boat. for FISLY 3 - www.pbase.com:443/waltercarels/image/129320450. I think the FISLY 3 is about 12' 5'' max from front wheel axle to rear wheel axle. Look at the FISLY class rules if you go that way. I don't know if this is something you would consider going to the Worlds with but we are only having FISLY class 3 no PAC rim class 3 this time. To my suprise there are quite a few FISLY 3 boats signed up all ready with the intent on competing. We may convert some of our boats to FISLY 3 specs. Some in the US all ready have. In europe it appears that the smaller FISLY class 3 boats are just as fast if not faster than most of the class 2 boats. I'm guessing because of their lightness and maneuverability. On a dry lake bed a bigger platform is better but more of a hassle to store transport and set up.
If you decide to go Pac Rim 3 I would build a spring board. I cut bulkheads to allow the spring board to go through them on the center line. I would use at least 3 bulkheads spaced out to receive them. I also made a longer plywood skinned fuselage too. It uses bulkheads and stringer construction technique. Both types of construction take about an equally long time to make. Ply wood boat or Wingnut 3-

Thanks US772
That is great info
Something thing I was not aware of is that the FISLY class3 are smaller than the PACRIM class3


Cisco
I will when I have enough info, the hull is the easy part.
So I guess I would think that I am still in the research stage.

I still have to find info on building a light wood wing mast.
Cheers
Vic
