Mamma Mia, something about the boat

 Mamma Mia is a Surprise class sailboat
bought brand new by the Yachting Club CERN in 2009.

Boat preparation: I will work hard to prepare the boat for the regatta, as priority:

Check all the components in particular the electrical system, and make a list of items to improve

Design and build the mount for the ST1000 autopilot and do the electrical connection properly

Clean the hull (at least, first big cleaning)

Why I like Mamma Mia: I immediately liked the Surprise class not only for the well known maneuverability, but mainly for the general purpose design of the boat, that performs extremely well in almost all the weather conditions I managed to sail it on the lake. It offer a lot of space inside, and a compact cockpit, perfect for solo outing.

Knowing the boat I am sailing: Surprise is the most popular sailing boat on the Geneva Lake, it is a Class C 6 people boat (10 people in class D according to constructor plate). First designed and builded by Archambauld Chantier in 1976, it has a fiberglass hull 7.65 meter lenght, a beam of 2.58m, a draft of only 1.6m, and a displacement of 1.350kg of which 600kg are cast iron ballast.

An aluminium Deck stepped Mast is 9.8 meter, with a classical Sloop Marconi 7/8 rig capable of hoisting a Main sail of 16.5 sqm, a Genoa of 14sqm or a Jib of 10sqm and a symmetrical spinnamer of 45 square meters. Total sail area upwind: 30.5 sqm, Downwind: 61.5sqm.
Mamma mia is equipped with a modern outboard Yamaha four stroke 6CV, that I will probably keep on board during the regatta... just in case.

A 12v battery power the navigation and interior lights, and will be crucial to validate the efficiency of the electrical system, as disqualification is expected in case of issue on navigation lights, plus, I would be happy to install and power properly a Raymarine ST1000 autopilot.

Registration number is GE-19209, I will sail with number  SUI 702 

Approximate hull speed (2.43xsqrt(LWL of 7.5m)) = 6.65 knots
