Boat Bash on Castle Rock Lake Mauston WI

Boat Bash Castle Rock Lake


Updated for Boat Bash 2019!

Boat Bash

The largest on-the-water party in the State of Wisconsin is set to take place Saturday, July 20 (2019 – update). Boat Bash is an annual Customer Appreciation Event put on by Smith II Marine, Castle Rock Marine, Docking Solutions and ELF Storage and usually takes place on either the third or fourth Saturday in July on Castle Rock Lake located in the Greater Mauston area. We’ll try to update this article each year, so current info will continue to be published, so be sure to bookmark it!

The Boat Bash kicks off at 12:00 p.m. and goes until 4:00 p.m. Boat Bash is sure to be fun for the whole family, but is honestly a bit of an adult venue, so please use your discretion. 

The Band

The event features ‘fun, beverages and live music’ on Alcatraz Island, this year’s featured band will again be The Playlist (formerly The Rabid Aardvarks) from Milwaukee. They are a cover band featuring two female vocalists and playing current and classic music from the past. They most recently have played at Miller Park and will be playing later this month at Potawatomi Bingo and Casino in Milwaukee. They were nominated as Wisconsin Cover Band of the Year. Here is a glimpse of one of another one of their performances and some background info. 

Getting To The Island

Information on where to launch and dock your boat and how to get to Alcatraz Island can be found on Click to zoom in on Castle Rock Lake. 

Check out this video of Alcatraz Island. It wasn’t taken during Boat Bash, but shows some incredible views of the island itself. It gives you a good idea of what the island looks like and what you’re looking for so you can find it. The water around the island is shallow and everyone just soaks up the music, food and drink while standing in the shallow water or sitting in their boats.

We hope to see you at the Island!

    Will there be a bathroom or port a potty for people to use?

      As you can see from the photo I don’t believe so, Jessica. The only way would be if other boat owners had them onboard and let you use it. This sponsored by the marinas and Docking Solutions, you might want to check with them directly.
