Answer 1

Hoist _this out of the bing function.

you should have

_this = this,
this.bing = function() {
            intervalID2 = setInterval(function(){
                console.log(_this.name);
            }, 500)   
}  

Javascript is imperative so you need to follow the execution path carefully. In function Ship, this points to a Ship object, in function bing, this points to the global scope (window). You need to save a reference to this so that you can refer back to it in these types of functions.
