    Looks that the model tends to sail on the chine upwind. This might an advantage upwind, but not pleasant downwind. Putting loads in the back helps. The hull planes easily. More rocker in the hull may be interesting?

    Transom extension? Nice use of a stream. How much weight did the bolt represent when right aft?

    If it is the IGUS, it was sold for 3300EUR.
