The Port To Port regatta is a international race downriver from Lasalle Mariners Yacht Club to our sister club, Grosse Isle Yacht Club USA that has become a tradition with the river sailors. It is held every June. With many shoals, island, mud flats, dikes, freighters and other river traffic, it can be a quite an interesting trip. No worries however, our American hosts make sure that we are well taken care of at GIYC with more than enough hospitality to keep you coming back year after year.
