MARITIME SAFETY RESEARCH

3am. Anchor holds.
But are you sleeping?

Everyone has an opinion about sleeping at anchor. Almost nobody has data. We're changing that.

5-6 minutes
100% anonymous
Published open-access

Every response makes the findings more accurate. The more sailors who take this, the more useful the research becomes for the whole sailing community.

YOUR ANCHOR SLEEP PROFILE

Why this matters

Published research shows sleep fragmentation — waking repeatedly during the night — can significantly degrade cognitive performance, even after a single night. Your responses help us quantify this effect specifically in the anchoring context, where the data gap is significant.

Your data is now part of the study. Every additional response increases the statistical power of the findings. This contributes to dedicated research into anchor-specific sleep quality in recreational sailing.

Optional — Market Research (not part of the academic survey)

How much would you pay for a trusted, dedicated anchor alarm device?
