In a large pot over medium heat, cook the chopped bacon until crisp.
Remove the bacon and set aside, leaving the rendered fat in the pot.
Add the diced onion, celery, and garlic to the pot, sautéing until the vegetables are softened and fragrant.
Stir in the diced potato, clam juice, thyme, sea salt, and black pepper.
Bring the mixture to a boil, then reduce heat and simmer for 10-12 minutes until the potatoes are fork-tender.
Use an immersion blender to lightly pulse the soup, thickening the base while leaving plenty of whole potato chunks.
Stir in the chopped shrimp and canned clams, cooking for 3 minutes until the shrimp is pink and opaque.
Pour in the coconut milk and stir until the chowder is creamy and heated through.
Serve hot in a bowl, garnished with the reserved crispy bacon.
