This is my latest design, a refinment
of Proto 2007,the one I would built if I had to do it right now.
And yes it still have the same name SuperSolo

Proto 2008 is based on the same design box than
my Proto 2001 design and is a refinement of it.
Proto 2008 will be a fast day sailor also called sportboat. This
sailboat is a concept boat. It is designed inside the
I need a boat for myself going
I want a boat that can stay on his feet from 0 to 30 knots with
me alone without sail change and reef.
The boat should be long enough for waterline speed and should
have a planning hull.
The boat should be optimized for the helmsman and a crew which
will be on trapeze and handle the spinnaker.
The boat should be light and easily driven with a
modest sail plan in all conditions.
To design an easily driven hull, Proto 2008 strong
characteristics emphasizes very narrow water line beam, and a fair
amount of rocker along with a narrow beam. I have chosen narrow
beam for a few reasons. First it goes easily through waves.
Second it makes a lighter hull in terms And
beside, a wide hull makes more wetted surface, needs more sail
power to compensate and more crew on the rail to counteract the
added sail power. More is less and less is more. I also
added a half chine form center to the back. Nowadays it is
very common to see chine on the latest speed designs. Volvo 70.
IACC, etc. Besides my last 2 boats had chines and I like it. I it
suppose to help lift the boat to weather and discipline the water
at the transom. Some test on reduced model and tank testing prove
that there is a gain.
Another particularity is a prolonged forward section. This has a
few purpose. One this makes a very fine entry which in conjunction
with rocker should help getting the bow out of waves. Second a fine
entry reduce the energy needed for going through water. Third, with
the head stay further back, leaves place for an asymmetric
spinnaker or code 0 clewed to the bow without bowsprit. This
simplify short handed handling and reduce the length of a possible
The appendice are high aspect ratio. The keel is a simple foil
with a lead bulb at the bottom which will be resposible for most of
the stability of the sailboat. The rudder is a cassette type.
Both are retractable.
Sail plan should carry about 300 sqf of sail surface. Something
like the Js 9000. Carbon mast with flexible top for bleeding
power carrying a big roach mainsail and a self-tacking jib.
This last item is not negotiable. I tested a high roach mainsail at
the end of the 2007 sailing season on SuperBlanc. I had positive
results on speed gains and the ability of the boat to carry more
sail area. More testing in 2008, but I am very pleased that I can
ad sailarea without changing the ballast amount. Although I may do
it with SuperSolo.
I am dreaming of a carbon epoxy sandwich construction, vacuum
bagged and oven cured. But a cold molded construction is more
realist at least for the first hull. I am very familiar with this
method using 3mm meranti plywood. It is light enough, stiff,
durable and strong. Anyway the small hull surface compensates for
the added weight compare to a bigger boat.
This project is for me and my needs to sail everyday. It is
quite difficult to bring along half a dozen crew in a short notice,
so this project is a compromise solution. Maybe some sailors out
there are thinking in the same way and could be interested in this
sailboat. Then it could be the beginning of a new adventure.
I am not a professional designer. Ideally this concept should be
revised by a naval architect and engineered accordingly. But I have
enough experience with similar sailboats for being confident in a
solid and durable performer.
