The word 'seabag' is formed from 'sea' (from Old English 'sǣ', meaning large body of saltwater) and 'bag' (from Old Norse 'baggi', meaning a sack or pouch). A seabag refers to a bag used for carrying items, particularly by sailors, associated with the sea.
Think of a 'large body of saltwater' ('sea') and a 'sack' ('bag') used to carry things, which helps you remember that a seabag is a bag for items related to the sea.
