Shawn, I took a look at the ship and I can see what the problem is there. Kenmo's model contains a massive 1.7 million polygons. That's a huge number of polygons for most people running average hardware to load in most enthusiast level 3d software. Although it is a very nice looking model with a great design, the object will, unfortunately, be far too heavy for most average users. Also, I think the reason it was taking so long to retopo is that it contains a number of very small subobjects and greebles, which should all be retopologized separately, then merged together afterward with the main part of the model. This would allow you to retopologize much more efficiently.
