Due to the ongoing global health crisis, Bay Marine Supply is still operational, but In-store transactions or consultations are not available until further notice. Orders may still be placed online for will-call pickup by entering coupon code localpickup during checkout. We will call you when your order is ready - PLEASE DO NOT come to will-call before you have received a call indicating that your order is ready.

Will-call pickup is at the rear of the warehouse. Masks are required at all times and hand sanitizer will be available at the pickup desk to help ensure the safety of your families and ours. Thank you for your patience and understanding through these trying times, and we wish you and your families fortune and health!
