Summer is close, but the water’s still a little chilly for swimming. Spend some time near the water this Memorial Day weekend, and enter the Float Your Boat Challenge!
All ages are welcome and encouraged to enter. This program is a stand-in for the Cardboard Regatta competition the Museum launched in May 2019 for Door County middle school students. Cardboard Regatta teaches students engineering, problem-solving and teamwork. DCMM educational programs emphasize the importance of Science, Technology, Engineering, Arts & Math (STEAM) in the area’s rich maritime economy.

Follow these FYBC Rules and Guidelines (or keep scrolling), and post your pictures/videos with #dcmaritime to Facebook and Instagram. 

We are asking students and anyone else who is interested to create, float, and share their boats with us online, using #dcmaritime.

Anyone who wants to be part of the “Float Your Boat Challenge” has 17 days to create, float and submit their creations online. All video and picture entries must be posted online to Facebook or Instagram with #dcmaritime by Sunday June 13. The “Float Your Boat Challenge!” results will be posted on the DCMM Facebook pages and Instagram on Monday, June 14.

There are 3 categories of boats for your crew to try to build:

  1. Newspaper: Use only newspaper to fold into a boat-like shape that will float in your kitchen sink – no tape or glue; Example design tutorial videos:

    2. Click for Intermediate
    3. Click for Advanced

2. Cardboard: This is a floating and weighted challenge. Use cardboard, adhesives like paper glue or tape, and create a boat-like shape that will float, and test how many pennies it can hold and still float; Click HERE to watch example design video.

3. Freeform: Use a combination of newspaper, cardboard, and adhesives to create a floating vessel. Then add pennies to see how much weight it will hold and still float. Creativity is key to this challenge – use boat types like schooners, pontoons or amphiboats for inspiration!

Hold sea trials in your kitchen sink. Take pictures or video of your boats floating, timing the float and adding weights until they sink. Then post your video/photos with #dcmaritime to enter the “Float Your Boat Challenge!” (Under 18? Please get parents’ permission to post video/photos if you’re in them.) Fun additional activity: Creeks in Door County are full of water right now, and following your boat down a creek is a lot of fun! (These also make fun videos!)

To ask questions, message Door County Maritime Museum on Facebook or Instagram, or email

Ms. Meacham’s STEAM (Science, Technology Engineering, Art, and Math) class at Southern Door School put together a fantastic compilation of videos showcasing the boats they built for the 2020 DCMM “Float Your Boat Challenge!”:
