Highly appreciated by specialists of almost all maritime countries that anchor was at the World Exhibition in Paris in 1867, why, when England began to design the first tower battleships, Admiral Halstead approved Trotman anchor anchor as a model for this type of combat naval ships. It is widely used in our days.Around the middle of the last century have appeared Trotman anchor "brother" - the anchor, proposed by British engineers, one of the anchor plants in the north of England, Batley and Miller. Instead welded to the spindle cheeks, they did a double spindle. At the foot inventors acquire spurs with holes, which anchor during the ascent could lay the hoist.However, the anchors, with swinging horns, there was one serious drawback: they represent a great danger to the ship's crew during their harvest on the deck in rough - moving the horns could injure people. Nevertheless, Porter's invention used in our days.
