In need of a shower location

ok guys..i need help picking a location for a co-ed shower...my dad doesn't want a restaurant he would like a yacht ..i think that's too expensive for a shower..we're anticipating about 100 people (don't ask)..preferably queens or nassau county....the place also doesn't have to have a full sit down dinner...buffet style or little hand held stuff is fine..please help...TIA

I remember back in the day one of my friend's wanted to do her Sweet 16 on a boat, and she checked out boats over in Freeport. I believe wherever she checked them out, she would've had to bring in her own food.

Then there's also those boats that sail around NYC that serve food and drinks. We took one from somewhere near Port Washington with FH's company. I think it was called Manorhaven Park or somewhere near there where we got the boat from.
