Discover the thrill of building your own imaginary ship -- with masts, wings, wheels or whatever suits you! Bring one from home or build it on-site with our free-play LEGOs to enter into our contests. Then learn to build STEM-based LEGO models of historic and naval vessels including our Tall Ship of Delaware.

All skills and ages welcome to join the fun thanks to support from the Kenny Family ShopRite Stores and the Kenny Family Foundation. See contest guidelines below.

STEM Models

Learn to build LEGO replicas of historic and naval ships using STEM-based design plans including Kalmar Nyckel, USS Gettysburg, CSS Virginia, USS Monitor and many more. Shipbuilding kits are organized by skill level so that all ages can participate. Build a ship, then return the kit and move to another station as you wish.
