Moving to Calambrone (Pisa)


Today we decided to move the boat to Calambrone for the winter season.


Calambrone is a place nearby the Livorno harbor.


Calambrone is famous because there are often sustained breeze (8-10 knots) with flat sea. The Livorno harbor protects the waters from waves. It’s a perfect place to practice the flight with ours flying A class Cat.



Too many waves…time for little maintenance

Put some marine grease on the hull’s caps and on the rudder’s pintles.

I used 1,5 mt of dacron tape to seal the trampoline to the cross of the boat


washed away the saltiness from the mast


and, most important, with the help of a friend of mine, we trimmed the recovery rope with my weight. Usually, if your weight is below 75 kg, you need to lengthen the recovery rope.



The daggerboards and how they work

The daggerboards of this Exploder A class cat are Z10 type; the last evolution of z-shaped,  they give more stability and allow to fly a little earlier.

When on the beach we can put them in useful compartments.

Cases are controlled with the blue sheet. Thanks to a closed-loop system below the trampoline we can control both daggerboards from any side of the boat.

Once inserted in the cases, we secure them with the red rope and a cleat at the top of the daggerboard.

When cases are all forward, we navigate in “no-fly mode” or “neutral”. The angle between the daggerboard and the hull is 90°; the boat has little lift but, more or less, it behaves like an A classic cat. While we push backwards the cases we entry in “fly mode”.

With medium wind (10-12 knots) we can put them at the level of the second hole. All these settings may vary also from the weight of the helmsman. The faster the boat is, the lesser we need to push backwards the daggerboards. We never push them beyond the third hole (2-3 cm) if we want to fly efficiently. The fact that we are flying doesn’t mean that we are fast.

Moreover, with the aid of little iron nails, we preset the lift that we want to have before going out.

The seven golden rules revealed

These are the seven golden rules for foiling an A Class Cat, handed down from father to son.

  1. Don’t be scared
  2. Fly a hull to come off foils
  3. Sail boat dead flat or even windward heal to get on foils
  4. Sheet out a lot to get on foils
  5. Sheet in really fast as boat come up onto foils and accelerates
  6. Once sheeted hard and going fast, just keep boat flat, with sheet and steering any hull flying is slow
  7. Practice, practice, practice
