Great Britain have qualified for every sailing class at the 2016 Olympic Games in Rio following their performances at the World Championships in Santander.
"It's been an interesting event and fairly challenging from a racing perspective over the last ten days or so," said Park.
"However, it's been pleasing to have managed to qualify the country for the Olympic Games at the first opportunity in each of the ten events, and to come away with four medals which was in line with our target coming here.
"That said, we were disappointed not to win a medal in the Nacra, the 470 Men and arguably we could have won one in the 49erFX as well halfway through the week."
The team secured four medals, which is two fewer than their six-medal return in Perth in 2011.
