Make history when you spend the night on USS Cobia, our fully restored World War II submarine.

The Wisconsin Maritime Museum has been the home of USS Cobia for 50 years. Founded as a submariners' memorial in 1969, we have grown to be the state's maritime museum with exhibits on shipwrecks, models, car ferries & subs.

Sub Bnb sleeps up to 50 people in sailors' bunks throughout the boat. The listed price includes the first five guests.

The space
USS Cobia is the best preserved World War II submarine in the country. It has been meticulously restored with amenities added like heat and air conditioning, making it perfect for year-round overnight visits.

Your stay will be as unique as the submarine. No two visits are exactly alike. With more than 50 different places to sleep, you get to choose your own adventure on USS Cobia.

During your stay, you're welcome to explore the submarine. Your stay includes a personalized behind-the-scenes tour through the boat. This staff person will be your point of contact and on-site all evening.

Your stay includes admission to the museum after-hours. All of our exhibits will remain on just for you throughout your visit. The theater is also ready for your group's private screening of a movie from our large library of maritime and submarine movies. Playing cards and board games are available for your use.

We provide bedding and toiletries. Showers and restrooms are on-site (in the museum) and available to all guests. A light breakfast and freshly brewed coffee (from a veteran-owned company, of course) will be served in the morning.

USS Cobia is only accessible via stairs and there are seven bulkhead doors to climb through to navigate the entire boat. The only access to get out onto the boat is through the museum.

Because we are an operational museum, our policies are a little different. You're welcome to stay several nights, but we will pack up and secure your items during the hours the museum and sub are open for tours.

The restrooms on Cobia are 76 years old. They're lovely, but they're not functional. The Museum's more modern restrooms and showers will be accessible to you at all times.

We're happy to store your food in the museum's kitchen. You're welcome to use the fridge, freezer and microwave there. The kitchen is stocked with coffee, tea and light snacks for you to enjoy during your visit.

Guest access
You'll have access to the entire submarine and the museum from 5pm until checkout. You will also be given a key to enter the staff door of the museum so you can come and go as you please during your stay.

Other things to note
We clean the submarine extensively before and after every stay and throughout the day.

The provided bedding is professionally cleaned.

Masks are required in the museum when we are open to the public. Staff are required to wear masks when with you and other guests.

The submarine has a new HVAC system and air purifiers are placed throughout the submarine for additional sanitization.
