"House Marinos" is a family name , who have a pride of their Greek ancestry , also word "Marinos" is related to sea , so they want include the Trident as a part of this logo , with letter M on it . For some particulary reason client want the trident not goes upside down , therefore during the process , i use the negative space to combine letter M with trident , i also add compass element , due the nature of "marinos" meaning and the pride of their Greek ancestry , Overall look this logo quite versatile , strong and timeless. : )
