The Nereids are the hand maidens of Poseidon

nereida poseidon


The present Nereida is a Najad 380, hull number 82, built by Najadvarvet at Henån on the island of Orust in Sweden, just north of Göteborg, and launched in April 2009 at Hamble Point, England. She is named after the 'nereids' of ancient Greek mythology who were the 'handmaidens of Poseidon' (or Neptune, as the Romans called him) - so she is a 'sea nymph'! On the sea-front at Puerto Vallarta in Mexico is a lovely bronze of Nereida and Poseidon - shown as mermaid and merman. (I found a smaller version of the same bronze on the seafront at Barra de Navidad.)
