3. Nautical Theme
The nautical theme is a timeless choice for a baby boy shower. Inspired by the sea, it incorporates shades of navy blue, white, and red, with anchors, sailboats, and lighthouses as key motifs.
Decorations can feature striped tablecloths, anchor centerpieces, and rope accents. A boat-shaped cake or cupcakes with sailboat toppers fit perfectly into this setting. Balloons in navy and white arranged as waves can also make a striking display.
Food could include seafood-inspired dishes like shrimp cocktail, fish-shaped crackers, and a sailor-themed dessert table. Drinks can be served in clear bottles labeled with nautical flags.

Games like pin the anchor on the boat or a sailor-themed trivia quiz make for lighthearted entertainment. Favors might include mini anchor keychains or small bags of saltwater taffy.
This theme works especially well for families who live near the coast or who simply love the ocean.
