The minelayer Vaindlo is a vessel of the Estonian Navy Mineships Division and also the second modernized Frauenlob-class minelayer. A silver star cross represents the light tower on the coat of arms of the vessel. The light tower also symbolizes the international connections between Estonia and her allies. The Red Saint George remembers the fallen British sailors in 1721, whose memorial plate is situated at Vaindloo island. The star cross is placed on Vihula´s municipality coat of arms and combined with the golden and silver lines they represent the ancient Estonian agriculture. The ship's motto is in Latin "Memento" which means in English "Remember". The coat of arms was designed by Priit Herodes. In 2003 a cooperation contract was signed between the Kunda city council and the minelayer Vaindlo which gave the vessel a right to wear the Kunda town coat of arms and to introduce the city in all foreign harbors across the world.
