Just for you Cisco.

Thank you for that. It's looking REAL good.

Judging by your work so far I am sure your seating solution is going to be so good that we will be saying "Why didn't I think of that."

You said in an earlier post that you weren't going to use that front wheel or the handle(foot)bars. I reckon those handle bars with their offset will be ideal adjusting for different height pilots as long as they can be clamped tight enough stop them twisting in the steering head.

At a rough guess I'll bet your costings come in well under the $1,000 mark. Excellent stuff iand. Cheers Cisco
P.S. Keep posting the pics.

Does this help? It's the best I could get it.

The sail I slapped on is my son's, the boom my next door neighbor's. But I might have a stormy sail coming on Wednesday. The mast support tube is just under 500mm, this was part of the design so a piece of PVC up to 240mm could be put in the tube to give more mast height, based on scaling off a photo of your LLM a sail/boom height of (by memory) 500mm, length of mast supported <250mm 500mm-250mm=250mm
therefore the mast I hope can come up/be extended by up to 240mm safely without adding a mast extension or any mod. I haven't added a internal support in the mast yet and have had a few more ideas regarding this.

I have to admit what you've said is reassuring as I've been VERY concerned about how far back the sail/rake is. My solution was to volunteer my son as the crash test dummy, I mean pilot (I might not be very bright but occasionally have flashes of brilliance). Also I'm unsure whether to go into much detail regards the construction of the seat (it is only a basic foam sandwich),the mould should be almost finished before going to work.

Landyacht
A mould for a foam sandwich/fiberglass seat , not a mould for a fiberglass seat.
I personally consider the advantages/disadvantages for me favor the foam sandwich/fiberglass construction.
Advantages
1-The mould can be built in a faction of the time,-couple of hours verses a couple of days (I like to take my time building things, this is one of my vices)
2-With very little effort the mould can adjusted for different body shapes and how far the back is reclined.
3-Far lighter (coming from a sailing boat background it's hard to remember weight is not as critical with a landyacht)
4-More rigid
5- No polishing the mould, release agent, gel coat, etc
6-When I finish with the mould I can knock it apart to use the wood for another project
7-Reinforced mounting points look no different to the rest of the seat

Disadvantages
1-Not as impact resistant
2-The seat itself takes longer to build (but this is easily offset by the mould)
3-Slightly dearer (but this is easily offset by the mould)
4-More easily marked and damaged.

I was considering a new thread about unconventional but cheap/easily built fiberglass moulds and a few other unconventional construction techniques. What do you think ?
Ian

Couple of photos showing the mould, the layup and how simple it is to adjust for body shape

WOW!! What type of foam is that and where do you get it?

Remember that land yachts are beam reachers like cats.

b#ll#cks to that . One of the things I dont like about te way ablowie rig works is that people can get away with being "dumb" sailors that just reach up and down the beach. . When the wind is in a "bad direction" and thy all pack up instead of taking up the challenge and learning to actually sail. With a good rig /sail and mast you can do almst anything.
GRRRRRRRRRRRRRRRRRRRR

Let me qualify it more. Possibly the best windward performing type of yacht is a deep fin keel sloop. They are able to claw their way off a lee shore better than most other yachts.
Catamarans are not generally regarded as good windward performers. One of the reasons for this is the speeds at which they travel. This has the result of bringing the apparrent wind direction closer to the bow and therefore creating the effect of pointing high into the wind.

Hence my comment:-"Remember land yachts are beam reachers like cats."

When I have been sailing my blowie, people have asked me "Do they sail to windward?" My usual response is "When you are travelling at 40 knots in 20 knots of breeze, you are pointing fairly high."

Re:-Packing up and going home when wind direction is not good. Sometimes this is not that easy to do and depends on the area where the sailing is taking place.
Beaches are by nature and definition, long and narrow. On Queen's Birthday weekend at Yeppoon late on the Saturday afternoon, I made a not terribly wise, but none the less calculated decision, to see how far it was possible to sail north on the beach to Corio Bay. Wind was around 15-20 kts south of east, so I knew it would be tacking on the return trip.

The trip up took 40 minutes travelling at 50-60 kmh. That equates to 30 odd klms and up there it is 4wd country with very little traffic. The trip back took 100 minutes with long and short tacks nearly all the way. The choices were, sail to your best ability, walk, or hope for help from a 4wd. Only saw one 4wd during the whole 2 hours and 20 mins.

With a good rig /sail and mast you can do almst anything. Absolutely. The paddock we sail in here in Bundaberg opposite the airport is a delight and we sail every inch of it (ie pointing, running and reaching) as you would be doing at Lefroy. I don't think you realise how envious the rest of us are.

The beach at Yeppoon could possibly be the best land sailing beach in the country, but a Lefroy it ain't.

When I have found and bought my 1,000 acre beach front, had it laser levelled and covered with hot mix bitumen, I will let you all know. I haven't worked out the entry fee yet but I will keep you posted.

Via con Dios Amogos, Cisco.

sorry folks I should have left this thread for that beautiful yacht

Progress hampered by stupidity but thought I should share as I was the one who said "I've found failure & problems a wealth of information when planning a project"
I started by breaking the foam trying to curve it to much- one repair job, while adding hardener to resin the top came off- one batch of resin ruined- trip to get more hardener, went to take photos- batteries dead- trip to get more batteries and on it goes. Some days it doesn't pay to get out of bed

The white stuff used to glue the foam together is a mix of resin and Q cells (only weighs slightly more than foam) you also use it to coat the entire surface to sand for surface preparation. But thats for tomorrow

Body filler can be used instead or a resin/talc mix. Tools for foam/sandwich construction are expensive- I use cream and milk contains for mixing, paddle pop sticks and scrap wood for stirring, ice cream lids for troweling, scissors and cheap utility knife for cutting, sandpaper glued to flexible wood for sanding convex curves flats and mild concave curves. You can add up the cost.
Ian

try using hot air gun that is what i have used with complete success,but would check on a off cut so you know how much heat to apply.

Sorry about the quality of the first photo, I was trying to show how it is tied to the mould to retain shape.

The inside of seat has been glassed. The string is cut and seat is off the mould.

Some general shaping and gaps filled prior to mounting point reinforcement and fibreglassing

Someone please tell me if I'm going into to much detail

reinforcing pads with blind threaded ss mounting point (yes it would have been easier to just reinforce drill and bolt)

The details are absolutely vital, keep them comming. I sometimes wonder if I submit too much detail about building my C/5, but the details are so very important. Without the finer details, people are left wondering "how did he do that?" When given the info, they can understand and either use it or say "what a great idea, I love it, but I think I can improve on it or I can alter it slightly and then use it for myself in my own situation". Keep them comming, please.
