Set sail with GetMyBoat.com app
GetMyBoat.com, for Android, iPhone, iPad, iPod Touch (requires iOS7 or later).
Offers a searchable database of more than 33,000 boat rentals available worldwide.
Boats range in size from kayaks and canoes to mega-yachts and fishing vessels.
[...] the feature that will get me to keep the app on my phone is the filter.
Click on filter and choose the type of boat that suits your mood: power, sail, fishing, non-powered or mega-yacht.
The app turned up significantly more search results when I searched Cabo San Lucas than when I searched on the website.
