Status: offline 		The plans of my Nightmare Mk VII (pdf.) can be sent to you - and every other interested person - for free!

Of course several modifications - like scale X-shape crossbars or wingmasts - can be applied by yourself,
but these plans will give you a stable basis to start with.

Just send your request to: ernst.zemann@gmx.net

Status: offline 		antigua 007 has already received the plans.

As an additional explaination:
I shape my hullplugs out of solid foam and cover them with three to four layers of 160 gr. glass (twill) with epoxy resin.
Then they are sanded (grain 40, 80, 120). PVA mold release is applied.
Then I laminate the lightweight shells with two layers of 160 gr. glass and two layers of 80 gr. glass.
Each single shell is sanded with the same sanding grains (40,80,120),
before I remove it from the plug.
This can be done with two layers of 160 gr. carbon also.

It is also possible, to cut out the cross sections from 3mm balsa and plank them up with 3mm balsa planks as well.
Then the hulls are covered with two layers of 160 gr. glass.

To make the building process easier for everyone, there are several picture galleries of different modeltrimarans at:

As said before, this year there will be around TEN Mini40 Trimarans and at least two 2M Trimarans.
The meeting will be 5th - 6th July 2008

Status: offline 		7 free selfbuildingplans in pdf. format have been sent out to prospects by now!

I´m already working on the design of "Nightmare Mk VIII".

All coordinates for new floats (more volume and even flatter keel rocker, higher freeboard at the bows))
and new mainhull (center of gravity even more aftward than before, higher bow freeboard as well)
are already here. Curved crossbars, if desired; - but everything else remains like it was on the Mk VII.

Is there anybody out there, who is able and willing to transform these data sets to a complete Autocad plan?
Cross sections, centerboard position, rc-set-up, rudder steering details, A-, B-, C- and D-rigg-dimensions and so on.

I definitely would need your help here.

Unfortunately I do not have any more contact to the person,
who was so nice to make the drawings of the Mk VII for all of us.

Just send an email to: ernst.zemann@gmx.net

Status: offline 		I am starting a new build the "Snapdragon" trimaran using the Traplet plans. I also got the Freight Train plans from Traplet and may try building that one in the future. Has anyone built and sailed the "Snapdragon" and if so are there any pitfalls to avoid. I am a very experienced builder and just completed a USOM. Being an accomplished multihull sailor of catamarans (Hobies, Tornados, Nacras) the thought of building a model multihull was intriguing. The Snapdragon plans do have good template details, but they lack overall details on radio placement shroud attachment and crossbar details. I can certainly overcome this, but if anyone has some thoughts to share I would appreciate it.

Status: offline 		Hi again!

Today I sent out plan No.10 to another prospect!
So the rc multihull scene seems to be a little quiet, but definitely not dead!

Status: offline 		The Snapdragon built is moving along. The main hull is complete- no deck or internals yet. and I've set up the forms to begin planking the first float. I have decided to alter the crossbeams and go to a molded CF reinforced curved beam, versus the straight CF tubes on the plan. I am also going to angle the floats up slightly, versus having the decks at the same elevation. I will be going to a curved deck profile at the bows which will get faired out as it moves aft. This should give it a little more forgiveness if it buries. I'm also laying out the sailplan and rigging details. I'm planning on using a profile similar to my USOM with a B rig sized jib (30%) and a larger more powerful main. It should come in around 1100 sq ins or thereabouts. It should be ideal as it will get sailed predominantly in the lighter winds that we have here. Mini40 - I wouldn't mind getting a look at your latest Nightmare plans/sketches to see were the design ideas are evolving in this class. I've seen photos of the earlier versions and I like the overall look of the design. You can reach me at terry.karaim@rogers.com. I'll post some photos of the build as soon as I get a chance.
