Plunging overboard into the icy ocean waters is a challenge that is hard to resist. Both invigorating and ultra-cold, this is an unforgettable experience. Those who rise to the challenge line up along the gangplank just in their swimwear and are attached to a safety rope. Then there’s nothing left to do but jump and enjoy the bracing chill for as long as you can stand. On returning to the gangplank, the crew will be waiting with towels and possibly a strong drink to help warm you back up.
