Hello,
Poured sockets are an industrial item, all about safety factor. And a good thing. But that tends to make them large and heavy. And they are used, industrially, for 7x19 and similar constructions, which are easy to "broom" inside the short length of the socket, and 1x19 isn't so co-operative. Loos tried to make a socket, years ago, called Castlok, that was compact, and infamous for being hard to form 1x19 wire into.
In addition, sockets require utter cleanliness for prep, and utter stillness when curing, things not always available in a yacht. And the potting material has a fairly short shelf life. There's just too much to deal with, when you can get 100% more quickly, lightly, and compactly with other terminals. It's doable, and it can be a fine terminal, but not easily on boats. Our local foundry makes a very nice, long model, suitable for 1x19. But again, big and heavy.
Having said that, I like sockets for some applications, like on 7x wire for big traditional vessels whose owners don't appreciate the yar elegance of splices and seizings. Different tools for different jobs.
Fair leads,
Brion Toss
