I have had a steel boat built .The person who was fitting the windows and engine and who gave me the person who as done the steel works as pulled out of doing this work saying that the sides of the boat are to straight .need to be carved and the cabin to small.It does not look wrong to me ,but i been told they are craved because of the bridges.My worry is theres something else wrong that he's not telling me.Do all boat companies have to have recreational craft directive declaration of conformity and what are the key points and does this devalue my boat if i don,t have one.

Need help please as i,m novice
