Hi

I will point to a Yahoo group where you can find free/download design
of various sizes and different types of construction. What is
interesting about the site is that it progress a new building method
develobed just to overcome some of the real troubles with ships
building and develobed to offer a hull at a third the cost, in modern
seaworty design , tree times the strength of tradisional construction
methods and acturly using the computer for the lofting and cutting of
the only material needed for these designs, sheet material.
The plans are free and cover tradisional small dinghies up to ocean
going combined sail/speed boats , please notis that as the plans are
CAD drawings, you can alter the designs by up or down scaling the
intire drawing and from a 12 meter heavy speed boat ,end up with a very
attractive and practic hull for a reliable and safe work boat.
A tradisional boat of some size simply need ribs or frames even in the
building process, so you can fit the unfolded panels onto somthing that
show the shape of the craft and act as substructure ---- with these
crafts the framework go one step further, as they are aranged in a 3D
pattern that make each frame be supported by all others, providing a
much stronger hull ,leading to a building technike that make the hull
as a thick shell of frames forming a honeycomb structure that covered
with the paneling end up as a most rugid construction where sheet
materials are the main building material, where nothing in the
framework need bending but is cut from sheet materials steel or plywood
..
These are most exiting designs in terms of ease of building while the
plans in full-scale show each detail, the hull consisting of a thick
shell with the perfect framework underneath offer a ready hull where
most time comsuming details are removed by design, --------- The
full-scale plans can acturly be spray-glued onto the sheet material
chosen for panels or framework and cut from the lines on the drawings
directly for perfect fit and a garentie of the hull shown in the plans,
the stability are better than what Lloyd ask and an option to foam
fill the honeycomb cubes promise a hull unable to sink one where you
can cut a hole in the back and place a big in-outboard thru an engine
well --- after the hull is build and before you chosen the engines.

Check the slideshow that show just a fraction of both old and the new
3D-Honeycomb based designs, anyway Cyber-Boat offer free download of
true 3D modern designs _and_ the unfolded panels plus building jig and
framework assembly, and any material you need, is sheet material of
your choice ; that be steel, premade glasfiber sheets with one side
nice turning outside making the finish as the first thing and the
framework as somthing you can cover with mat and resin and just leave
there using it first as building jig and later as permanent honeycomb
framework.

Now please check the site, there are several orther groups with
designs, you will find the links at the main group's homepage --- Btw.
check a search about 3D-Honeycomb as the method also build a house at a
third the cost four times as strong and only halve the trouble building
