La Madera, La Ropa and Z pirates

Can someone educate me regarding where does La Madera colonia stops and La Ropa colonia begins?

Not sure what your confusion is. Is there an address you're confused about or is this just some idle curiosity?

Colonia La Madera stops more or less at the Xiguacán condos and Colonia La Ropa begins more or less at La Casa Que Canta hotel. The promontory area in between is known as El Eslabón where in 1742 the British ship "Centurion" captained by the corsair George Anson sank the Spanish galleon "Nuestra Señora del Monte Carmelo" which became grounded on the rocks there and over the years as it came apart its wooden planks would float up on the beach from where it got its name Playa La Madera.
