Your Local Marina of Choice

Are you ready to cruise the water in style? MacDonald Marine is the place to start your fun and safe day on the lake. We are home to the widest, smoothest boat ramp on Lake Mahopac; convenient, float-up access to gas; and sheltered, secure slips to keep your boat on the lake. 

Spend Less Time At the Ramp, More Time On the Water

MacDonald Marine is home to Lake Mahopac's widest, smoothest, most convenient boat launch. There is no quicker way to get on the lake and start your fun.

Daily Ramp Fee

*Please Pay Before Launching*

Have Tie Downs removed and boat ready before entering ramp.

  • $20.00 Daily Fee for use of ramp

Launch Hours: Tuesday thru Friday 9:00am-6:00pm. Saturday and Sunday ramp opens at 9am but no launches into the lake after 2pm and you can pull out of the lake up to 5:30pm. Closed Mondays. (Ramp closes at 6:00!) 

Don't Leave the Water Just for Fuel

Nothing stops a day on the lake faster than having to go get more gas for the boat. At MacDonald Marine, just float up to our convenient lakeside pump and we'll have you fueled up and back out on the lake before you know it. Pump is open Tuesday thru Sunday, from 9:00am-6:00pm. Closed Mondays
