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.

If I was able to take a decent photo you could see the front wheel is a different wheel with a brake. The handle bars/foot bars have been cut, offset reduced and straightened (mods are only a hacksaw and welder away)
Costing at this point is under $250 (I would be more than happy to give a brake down if interested, I am trying not to bore people) The sail I'll initially use will be an old original windsurfer (the brand) sail, so I don't destroy a decent sail learning how to recut it (I'm checking out Landyacht's thread on recutting sails).

I would make a small extension for the top of the mast and use that sail exactly as is. The have been some real success stories lately with wishbone rigs. Sme of those 4m surf sails are already flat enough.
I would try it with the wishbone first really
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.
if you use that wishbone and the downhaul set up you shouldnt need to do anything to the mast internally. I would let it drop in 250mm and leave it there. looks good

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.

, a mold for a landyacht seat
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

boat building foam, talk to your local fibreglass supplier
comes in a variety of densities and thicknesses
the strength of the construction lies in the separation of the fiberglass skins
you can build a 12.5 ft sailing boat that weighs approx. 40kg that is stronger than a wood boat
a layer of fibreglass on both sides generates immense strength. mounting points are reinforced by gouging out foam and inserting wood or fibreglass
even some sydney to hobart boats are built using this construction
Pardon my lack of knowledge but what is a 'beam reach'? Not from a sailing background you see 
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
I used a hot air gun on the centre panel but got lazy,hence the saw cuts-basically I went to thick in the foam for the amount of curve, I would have been better off layering two 8mm pieces. Thanks for the suggestion.
Ian
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.

Mounts are in and I better start fibreglassing before Kody (with a little help from Joe) finish their landyacht.
