I fell bonkers in love with the 41 when it came out in '86. The new look was aggressive, yet stylish and functional all at the same time! So what's your question? If it's a Hatteras of that era, it's a very well built boat. GM671TIs were the popular power option at the time. If you've found a truly nice one of these at a fair price, buy it and enjoy it!
In 1986, The 41 Hatteras, and the 41 Viking were pretty much the only game in town. This is also the year Bertram came out with the Awesome "New Style" 37 Convertible to replace every 35-40ft design they offered in that size range. Hatteras was late to the banquet with this model. The Viking 41 was already a market "hit" for 3 years when the Hatteras 41 arrived. Then, in 1990, the ill advised "luxury tax" on boats, brought this market and the entire American Marine Industry to a grinding halt. That's why there aren't too many 41s out there.
