Sweet Sixteen On A Boat

I am planning a sweet sixteen for my daughter in 2 months--It is going to be held on a boat--that does dinner cruises--it is a private party with a DJ and sit down dinner ( must be sit down because of the space)--I have read SO many messages about parties--but would like ideas from anyone who might have had theirs on a boat--picture ideas/decorations/sweet sixteen ideas--I would appreciate any help---Thanks!!!
