Due to the ongoing global health crisis, Bay Marine Supply personnel are working remotely for the foreseeable future, but we are still operational! In-store transactions or consultations are NOT AVAILABLE at this time, but orders may still be placed for will-call pickup by entering coupon code localpickup during checkout. If you place an order for will-call pickup, our S/R specialists will call you when your order has been pulled and 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.

Orders of in-stock items placed before 12 noon Pacific will usually ship or be available for pickup same-day; orders placed after 12 noon will usually ship or be available next-business-day. Please note that, as global manufacturing has slowed due to the pandemic while at the same time demand has skyrocketed, item availability is subject to rapid change. If an item you order is out of stock, we will contact you to let you know and offer -if we have it- the projected lead time for restocking.

Thank you for your patience and understanding through these trying times, and we wish you and your families fortune and health!
