Delta is known for quality builds and refits. The 70 series was very popular but became pricier with each refit and resale. I know 3 of the 70's, each a spectacular yacht; one of them was owned by a serious sailor who made the switch to trawler in purchasing a Delta 70 whose previous owner upgraded from a Nordhavn 62. The new owner did a massive (read expensive) refit at Hinckley and subsequently put her up for sale. If you can handle the price, they are seaworthy as well as special yachts.
