A French's boat history around the world

Hello everybody

I am very proud to join your community, because I found on this sailum network a very nice sloop that my parents build between 1971 and 1975 in France.

My father (he is 82) have just discovered somme news of this boat in a sailing book, name "around Mong" from Johan de Cat (page 46 to 56).
We will be very happy to be able to contact the new owner of this French story started in Le Havre in 1971..."Warwick" if you are curious of the seven first years of history of this "El Kouba"!
We are waiting your answer.
Best regards over world sailers...
