Hi Kurtis,
that's some very good news! I have the same situation, I started this a few months ago but put on hold because had some other things with higher priority. But last week I resumed it and hope will finish soon and post it on this forum if you're interested.
Just like you, I was also thinking to start from scratch again because I feel like I know a lot more now but I am reluctant to do it, because even if I start again I'm sure there will always be some things to improve anyway. I hope I will have time to a new model in the future that will look better and more realistic and authentic.
And yes, indeed, modeling itself is quite simple, no complex shapes but I got stuck because I never had any experience with ships before. It is hard to make it look at least somewhat realistic without spending a lot of time on researh. I was using this forum to look around some topics and saw many other works that helped me a lot though but it seems I still just touched the tip of the iceburg. I think it can take me years to learn about this ship stuff
