Backpacks & Backpack

20–25 L is suitable for day trips, commuting to the harbor, and shore leave (jacket, water, documents, tablet). 30–40 L is ideal for weekend cruises or as carry-on luggage if you also need to bring oilskins, shoes, or provisions. For longer trips, many people combine a large duffel bag (main luggage) with a backpack as an on-board and shore bag.

Water-repellent is usually sufficient for the harbor, short rain showers, and below deck. If the bag is left in the cockpit, goes along in the dinghy, or needs to stay completely dry during heavy rain, a waterproof roll-top backpack (taped seams/internal coating) is recommended. For sensitive electronics, a dry bag or pack liner is also a good safeguard.

Key features include durable, abrasion-resistant materials, sturdy zippers or a roll-top closure, non-slip straps, a padded back panel, and a surface that’s easy to wipe clean. Compression straps, D-rings, and a shape that fits in lockers or under the berth are practical additions.

When it comes to bags, “compatibility” primarily refers to practical fit: dimensions must match the storage locker/cabin, compartments must fit your equipment (laptop/tablet size), and attachment options must suit your needs (e.g., carabiners, life belt, buggy/trailer). If you already use dry bags, pack liners, or organizers, the backpack should match them in terms of volume and opening.

Heavy items (water bottle, tools, power bank) close to your back; delicate items (tablet/optics) in padded compartments. Keep boarding documents and your cell phone in a compartment that’s easy to reach and as protected as possible. For “wet/dry” items: place wet gloves or oilskins in a separate compartment or an inner pouch. This keeps the rest clean and dry.

After contact with salt or spray, rinse with fresh water, let it dry open, and do not store it while damp. Clean zippers of sand and salt, and keep roll-top closures clean. For waterproof backpacks: avoid sharp creases for extended periods to protect the coatings.
