Among various other business interests, my Gramps had the Elco dealership for New England in the 30s. Although he was mainly a sailor, he loved all sorts of boats, and the dealership made it possible for him to have a new Elco every year. I still think of the Elco as the classic yacht. You can still buy them, if you want to can afford to mess with wooden hulls. The history of Elco here. (BTW, PT 109 was built by Elco.) He donated his last Elco to the war effort. It was shipped to Britain, and used at Dunkirk.
Here's a 1925 57' Flat Top Motor Yacht ($195,000):
Here's a 1938 34' Sedan Cruiser ($137,000):
A sight for sore eyes, especially considering the vulgar, non-nautical appearance of most modern motor yachts. You can look at other old Elcos for sale here.
