Why Every Sailor Needs Quality Dry Bags
Dry bags are one of those essential pieces of sailing gear that you don’t realize how much you need until you’ve lost something important to water damage. Whether you’re heading out for a day sail, planning an overnight cruise, or embarking on a multi-week passage, keeping your electronics, documents, and personal items dry is absolutely critical.
A good dry bag protects everything from your phone and camera to spare clothes, medications, and important navigation papers. For sailors looking for other essential gear, check our sailing knife and multi-tool guide as well. The difference between a successful sailing trip and a frustrating one often comes down to whether you had the right waterproof storage for your gear.
Types of Dry Bags for Sailors
Understanding the different types of dry bags helps you choose the right ones for your specific needs on the water.
Roll-Top Dry Bags
The roll-top closure is the most common and reliable design. You simply fold the top down multiple times before buckling or clipping it closed, creating a watertight seal through compression rather than complex mechanisms. This design is proven, simple to use with wet hands, and extremely durable.
Zipper-Seal Dry Bags
These bags feature waterproof zippers that create a sealed closure. While convenient for quick access, zipper seals can be more prone to failure if sand or debris gets caught in the teeth. They’re best suited for calmer conditions where you need frequent access.
Hose-Top Dry Bags
These bags use a roll-top design with an integrated hose and valve that allows you to inflate the bag, making it float on the water. This is particularly useful if your dinghy capsizes or if you accidentally drop the bag overboard.
Dry Bag Backpacks
For sailors who need hands-free carrying options, dry bag backpacks combine waterproof storage with comfortable shoulder straps and chest buckles. These are ideal for beaching, hiking to shore, or any situation where you need both waterproof protection and easy transport.
Key Features to Look For
When shopping for sailing dry bags, consider these essential features that separate quality products from cheap knockoffs.
Waterproof Rating
Look for bags rated IPX7 or higher, which means they can be submerged in water up to 1 meter deep for 30 minutes without leaking. For serious sailing applications where your bag might end up underwater during a capsize, this rating is essential.
Buckle Quality
The buckles on dry bags take constant abuse from salt spray, UV exposure, and rough handling. Cheap plastic buckles break easily. Look for bags with robust nylon or metal buckles that won’t fail when you need them most.
Attachment Points
D-rings, lash points, and clip attachments let you secure your dry bag to railings, cleats, or other boat fixtures. This prevents loss overboard and keeps your gear organized on deck where you can access it easily.
Size Options
Dry bags come in sizes ranging from 1 liter (for phones and small items) up to 100 liters (for extended cruising). Most sailors benefit from having multiple sizes: a small bag for valuables, medium bags for clothing and gear, and larger options for overnight trips.

Dry Bag Accessories and Add-Ons
Several accessories can enhance the functionality of your dry bags for sailing applications, and when paired with quality sailing footwear, you will be fully prepared for any water-based adventure.
Vacuum Seal Bags
Vacuum seal bags let you compress clothing and soft items to save space in your dry bag. This is particularly useful for extended cruising where storage space is at a premium. Simply pack your clothes, remove the air with a pump or vacuum cleaner, and seal.
Dry Bag Clips and Carabiners
Heavy-duty clips and carabiners let you attach dry bags to railings, cleats, and other boat fixtures. Look for stainless steel or corrosion-resistant options that won’t fail in saltwater environments.

Dry Bag Care and Maintenance
Proper care extends the life of your dry bags significantly and ensures they continue to perform reliably on the water.
Rinsing After Use
Always rinse your dry bag with fresh water after use, especially in saltwater environments. Salt crystals can degrade fabric and damage buckles over time. Pay special attention to the roll-top area where salt buildup is most likely.
Drying Before Storage
Never store a damp dry bag — this promotes mold growth and fabric degradation. Open your bag completely and hang it in a well-ventilated area until fully dry before rolling it up for storage.
Buckle Maintenance
Check buckles regularly for cracks or wear, especially on bags that see heavy use. Apply silicone lubricant to buckle mechanisms annually to keep them functioning smoothly. Replace any buckles showing signs of failure immediately.
Storage Conditions
Store dry bags in a cool, dry place away from direct sunlight. UV exposure degrades waterproof coatings over time, so avoid leaving your bags on deck for extended periods when not in use.
Frequently Asked Questions
How do I know if my dry bag is still waterproof?
The simplest test is to fill the bag with air and submerge it in water. If bubbles appear, you have a leak. Also check that buckles close securely and that the roll-top folds evenly without gaps.
Can I use a regular backpack as a dry bag?
No — standard backpacks are not waterproof and will allow water to seep through seams and zippers. If you need waterproof protection, invest in a proper dry bag or at minimum use a dry bag liner inside your backpack.
How many dry bags do I need for sailing?
Most sailors benefit from having 2-4 dry bags of different sizes: one small bag (1-5L) for valuables like phones and documents, one medium bag (10-20L) for clothing and gear, and optionally a larger bag (30-50L) for overnight trips.
Are expensive dry bags worth the investment?
If you sail regularly or plan extended cruises, yes — premium dry bags offer better durability, more reliable closures, and longer lifespans. For occasional day sailing, budget options provide adequate protection at lower cost.
Final Recommendations
The best dry bag for your sailing needs depends on how you use it and what level of waterproofing you require. For most sailors, investing in a quality Ortlieb or Sea to Summit bag provides the best combination of reliability and value over time.
Don’t skimp on buckles — this is where cheap bags fail first. And always carry at least one small dry bag for your phone and important documents, regardless of how you plan to use larger bags for clothing and gear.
A good set of dry bags is one of the most practical investments you can make as a sailor. They’re relatively inexpensive compared to replacing water-damaged electronics or ruined clothing, and they provide peace of mind on every trip out on the water.
