Evolution f5g

Photos of low boom design, on f5g evolution:

The vang is a bicycle spoke and its nut can be rotated inside an aluminum tube for adjustment

the boom can be set at a minimum height of 6mm above the deck before it would hit the keelfinn nut

Sail servo is mounted in the front part of the boat

Project evolution is an exercise in weight distributionin.
The servos(for the optional forward rudder, sail servo), the batteries and Rx are put into the bow, so that the finn can be moved backwards.
The idea behind such weight distribution is to have the bulb on a long arm far aft. The moment of this arm "sinks" the stern and lifts the bow up.
This is a motion found in dinghies like laser, when the helmsman hikes hard on the straps and leans back, this way he accelerates the boat.(by pumping, and trimming the dinghy hull relative to the water surface).

 My prediction is that this weight distribution will improve reaching and running speed.
upwind the boat will be "stiff", unhappy to go over the waves, hopefully this won't produce a boat with a heavy bow, that slams into waves.
Tacking will be snappy, but the boat won't have much momentum to punch throught the waves when pointing directly into the wind.

evolution tasted the water for the first time today, no leaks,weighed down to he desired 1600g displ

With 1600g this boat is looking to be on the light side.(most national class boats weight 1700-2000g)

the coil behind the mast ramm represents the weight of the rigg(165g), the two battery packs are the finn and bulb(800g)
