Notes From Captain Demal

Hello mates! I’m Demal Mattson, a Charleston native and trained professional chef. I’ve spent a lifetime on the water exploring all that the Lowcountry has to offer. As a trained chef, I’ve worked with groups large and small for over 10 years as a private chef and caterer. I’m known for using fresh, local ingredients because I grew up being taught by my father how to hunt and fish and use these locally-gathered ingredients to prepare meals. Through Seas the Day boat charters, i’m able to share this passion as well.
