If you go to the Straddie Sales and Rentals website http://www.straddiesalesrentals.com.au/ you will find plenty of places for rent. Amity Point is the best place to put your boat in to access most areas of the bay and outside as well. You will find most places to rent here have off street parking for boats and the like and as long as you pick a place that is not waterfront the prices are pretty reasonable.
