Brass Nautical Ships 5 Minute Sand Timer Hour Glass

This 5 minute brass nautical sand timer hour glass would be a great piece of maritime decor and fully functional item to adorn a yacht club or to add to any room in your home, boat, or sailing vessel. The brass hour glass measures 6 1/2" Tall by 5" Wide and 4 1/2" Deep. This brass maritime sand timer hourglass was used to determine the rate of speed of ships before modern equipment. Knots were spaced along a log-line every 47 feet 3 inches. The number of knots that ran out in 5 minutes as the line drew out astern gave the rate of speed. One knot was equivalent to 1 nautical mile per hour. Great functional desk decor, this sand time can allow your guests an appropriate amount of time to interrupt what you're doing, while displaying your love for maritime history. This great conversational piece ships brand new with box in manufacturer's packaging with our 100% Customer Satisfaction Guarantee.
