Why does the USS Zumwalt look so weird?
The USS Zumwalt, with its knifelike bow, is more stable in heavy seas that other destroyers and cruisers. The hull widens as it nears the water, and at the bow at the water’s edge is longer than it is on the main deck. The result is a ship that looks like a knife cutting through water, giving it a sleek, stealthy look.
What is a Tumblehome transom?
Tumblehome is a term describing a hull which grows narrower above the waterline than its beam. A small amount of tumblehome is normal in many naval architecture designs in order to allow any small projections at deck level to clear wharves.
Why was the Zumwalt Class Cancelled?
In 2016, the Navy canceled the AGS’s Long Range Land-Attack Projectile because the reduced Zumwalt plan pushed the cost per round up to more than $800,000. And in 2018, the Navy said that even with the high cost of the round, the system was also failing to achieve the range the Navy was seeking, Vice Adm.
How much did the Zumwalt cost?
In April 2016, the U.S. Naval Institute stated the total cost of the three Zumwalt ships is about $22.5 billion with research and development costs, which is an average of $7.5 billion per ship.
How does a tumblehome work?
Tumblehome (the width between the gunwales is less than the overall width of the canoe) allows the canoe to be paddled without giving up hull displacement — which determines weight-carrying capacity (burden). The greater the displacement, the greater the carrying capacity.
Where is the tumblehome on a ship?
In ship designing, the tumblehome is the narrowing of a ship’s hull with greater distance above the water-line. Expressed more technically, it is present when the beam at the uppermost deck is less than the maximum beam of the vessel.

What kind of Hull does the USS Zumwalt have?
USS Zumwalt moored in Ketchikan, Alaska, March 2019. Unlike most contemporary warships—or any ships for that matter—the Zumwalt uses a so-called “tumblehome” hull. The hull widens as it nears the water, and at the bow at the water’s edge is longer than it is on the main deck.
How is the Zumwalt strange design actually helps it handle?
The big destroyer only looks unstable. Critics of the Zumwalt -class destroyers have worried that the ship’s design could lead to instability at sea. The destroyer uses a unique “tumblehome hull” design. According to sailors that have spent time on the ship at sea, it actually handles rough seas better than most ships.
What makes the Zumwalt so good at sailing?
The Zumwalt reportedly quickly rights itself in rough waters, faster than other designs. Sailors also described turns as more of a “drift” or slide through the water than other ships. Captain Carlson attributed the Zumwalt ’s stability to hull form, relative location of the rudder stops, and the size of the propellers.
