LOL Hey Byron and Sky, aren't you boys always talking about quality is better than quantity?

Who the hell cares how many 58's were made vs 53's? Economic conditions probably dictated how many 58TC's were built, but that is just a suggestion as I really do not know.
Sometimes manufacturers realize they have put too much into a particular design and discontinue it because they can make more money with something else. Maybe one of us should call Hatteras and see if they want to offer their view on this subject. In the end, it really doesn't matter does it?
As to my limited time in running this boat, what do you think I would have viewed differently by running this boat sporadically for six months vs running it in proper running condition for about 20 hours over a three day period? I have run many a Hatt after I bought this 58. None impressed me as being better in any way other than the bigger ones I have run which impressed me as simply being bigger. Truth is, mine felt the same or better than any other Hatt I have ever operated. Should I list the ones I have operated for you? It really doesn't matter as it is just my opinion, but I assure you, this part of my opinion is not biased. It is just based on the facts of what I have experienced.
I bought this 58TC for one reason and one reason only, price. Had I found a 53ED or 58MY for $117K in the same condition, who the hell knows what I would have bought. I was prepared to spend at least twice that amount, but there is no way I would have done that after viewing and running this boat. EVERY design has differences which can be viewed as positive or negative, it all boils down to personal preference.
I have to tell you, split stand up engine rooms do absolutely nothing for me. I've been on boats that have these, and they simply do not impress me. Now a big full beam stand-up engine room like on a 70 seems to give the best of both worlds, but that boat is not in the running for Bill (unless he has mood swings like I do!). Sure, you can stand up in a split engine room, but they make a long dungeon-like hallway where the 58TC has a mid stateroom and two heads. The split engine rooms give very limited access to the inside half of the engine. You have to remove a panel to access this portion of the engines. IMHO two choices of entry into an engine room is better than one. The 58TC has that. You can literally remove every square inch of the salon floor via hatches to give you way more headroom than you will ever find in ANY other engine room on a Hatteras, period. Entering through the steps in the galley is fine for general maintenance.
Then becomes the issue of what is involved should you want or need to remove the engines completely. You have to cut the top out of the lower salon roof to remove the engines. Sounds scary, but I am told it is no big deal and was designed with that in mind. How the heck do you remove the engines in a split walk-in engine room. To my knowledge, you don't. Unless of course you want to cut out the side of the hull. I've heard this is really not a big deal either, but it would scare the hell out of me.
I am not sure how Angela views a 58TC as having more ups and downs than a 58MY. As memory serves, there is no difference in this area. The 58TC has an upper salon/pilothouse, one level. Three steps down to the lower salon which is one level. Three steps down aft of the main salon is the companionway leading to the aft master with a guest stateroom to port, and two back to back identical heads to starboard with one having private access to the master only. Three steps down from the main salon forward is the galley and foward stateroom with a head to starboard, all on one level. Sounds like four different levels to me. I looked at my hand and had one finger left over!
Granted looks aren't everything, but who wants an ugly woman when you can have a pretty one? Who buys an ugly house, car, truck... whatever, over a pretty one? Shallow?, maybe. But I think everyone who has expressed an opinion has agreed with me that the 58TC is prettier than its "houseboatish" 58 and 53 counterparts. The 58TC feels like a much larger boat than even a 70 because of that long sleek foredeck.
Sum this short story up like it began, it is all just a matter of personal taste and preference tempered by price. My 58TC is pretty, and the price is unbeatable in any comparison. Why didn't I just say that in the first place?
