This summer that could change, because boat rental site Sailo just launched a new tool that makes planning your own boat party surprisingly simple, at a wide range of price points. SailoWay lets you create an event, choose the boat (or boats) you'd like to use, plan an itinerary and route, and invite and interact with guests. If you're charging for the event you can also set ticket prices, or if you're just splitting the cost with friends, you can track and manage their payments. [links]
