After conducting research, it appears that there is no boat ramp specifically named Main Street Presque Isle in Maine. However, there is a boat ramp located in Presque Isle that services the Aroostook River. This boat ramp is located off of Riverside Drive and is known as the Riverside Drive Boat Launch.

The Riverside Drive Boat Launch is a concrete boat ramp with a width of 16 feet. It services the Aroostook River and allows for access to both upstream and downstream portions of the river. The Aroostook River is primarily used for recreational activities such as fishing, canoeing, and kayaking. Motorized watercraft are also permitted on the river.

According to the Maine Department of Inland Fisheries and Wildlife, there are no specific restrictions on the types of watercraft that can be used on the Aroostook River. However, it is recommended that boaters use caution and be aware of potentially hazardous conditions such as strong currents and submerged rocks. It is also important to follow all boating safety regulations and guidelines to ensure a safe and enjoyable experience on the water.
