• 'his broad shadow' - shadow implies he isnt as good as him. broad implies he has large steps to follow which means it will be difficult. this also conveys idolisation as he is trying to be like him
• 'i stumbled' implies incertainty of ability to follow after him. it also implies the inexperience he had due to his young age. shows that he is in the depth of vivid childhood memories
• 'his shoulders globed like a full sail strung' - boats need a sail to move which emphasises his admiration of his fathers power. sibilance of 'shoulders' and 'sail' suggest the father works very smoothly which is very impressive to the son. extended metaphor of sailing which takes skill.
