For wet small-boat transfers, choose a proper waterproof phone case or sealed pouch with a verified water-resistance rating and a secure retention system. A normal phone’s factory water-resistance rating is not a reason to expose it deliberately to salt spray or repeated wet handling.
Check the complete product rating
Look for a clearly stated IP rating and manufacturer instructions. The closure is critical: inspect seals before each use and replace damaged pouches rather than trusting them.
Test camera and touchscreen operation
Some pouches reduce image quality, create reflections or make wet touchscreens difficult to operate. Test the exact phone/case combination at home.
Secure it to yourself
A wrist or neck retention system can prevent a dropped phone from disappearing overboard, but follow crew instructions about loose straps during boarding and landing.
Do a tissue test before trusting a pouch
Before travel, close the waterproof pouch around dry tissue and immerse it according to the manufacturer’s instructions. If the tissue gets wet, do not risk a phone. Repeat inspection as seals age. Salt water is particularly hard on electronics, so rinse the outside of the closed case with fresh water when appropriate and dry it before opening.
Check the waterproof claim carefully
Look for a manufacturer-stated immersion or IP rating rather than assuming every clear phone pouch is equally waterproof. Inspect the seal before each boat day, keep the lanyard secured, and test camera controls through the case before leaving shore.
