The i550 is a simple to build Sport
Boat which will deliver outstanding high performance.

Have you always wanted a performance
sportboat, but didn’t have a performance sportboat
wallet? The original i550 was created for the MicroTon
class, and has since been upgraded and redrawn as
a one-off sportboat for fleet racing.
It’s ease of building for the amateur builder
with “stitch-and-glue” method ensures
a light, solid hull, and a quick build for even those
with NO boat building experience.
Due to it’s simple construction
method, there’s not much to the construction
process. The whole thing can be cutout, and “stitched”
together in a weekend. The construction process is
fairly simple and straightforward; The wood panels
are cutout and “stitched” together in
a string jig to keep the boat symmetric. Once the
boat has been stitched, the open hull is left right
side up, and the seams glued with glass tape and epoxy.
Frames are set in the boat, and taped with epoxy in
place. The whole interior can then be epoxied and
finished before adding the decking.
Decking comes next, then the hull exterior itself.
The boat is still light enough in this stage that
it can be easily turned over with the help of come
friends. The bottom faired and finished and the hull
turned back upright. Rigging is added, and any interior
details come next. Sounds simple? That’s because
it is. Total build time is typically about 200 man
There is room down below for simple accommodations,
and “camp style” sleeping. Plenty of room
on deck ensures comfort both up and downwind. A bulbed
keel gives stability and righting moment while allowing
the boat to keep dinghy like performance.
The plans pack consists of: Construction Notes, Suggested
Bill of Material, profile, plan and section views,
nesting diagram, hull panel diagrams, frame diagrams,
interior piece diagrams, keel and keelbox diagram,
rudder diagram, cabin trunk diagram, deck layout diagram,
and a rigging diagram. The plans pack is all A sized
drawings in a easy to work with binder. Plans include
both the standard, and extended cockpit version.
The rig can be obtained through a number of sources.
We’ve put together a rig package for North American
builders available upon request. Additionally, we
plan to offer hull kits, and keel bulbs in the not
so distant future. Check back soon for more information.
This boat has been built in 3 sizes, ranging from
the i550, to the MG25, to the MG30. Plans are currently
being redrawn for the latter two models and will be
available soon. There are also a number of other designs
coming; a smaller 15 foot sportboat, that is in the
works, check back in the coming months for more details
on these projects.

This is a great way to afford a high
performance sport boat at a fraction of the cost of
other offerings of this type of sailboat.
If the builder is resourceful it can be sailing for
less than $5,000. If the builder uses all the best
brand new sails, mast, hardware and a trailer it can
be sailing for $9,000.
It is fast, speeds in excess of 16
knots are quite possible!
Several of the photos in this
article were submitted by Andrew Clauson in Australia.
Andrew built the boat in a few seasons time, and
will be racing other 6m sized sportboats. For more
