With two people onboard my TheMightyHobie18 last year, we caught two other H18s that each had 7 people onboard in Charleston, SC. The boats were handling it but waves were constantly coming overtop of the hulls. Before we could transfer some to my boat, a storm came up and since they were very near their launch spot (and I was not) we turned around for home. That would have been a great party! (16 people between three Hobie 18s).
