The TE series appears to be exactly what I was looking for. It even mentions "Profurl".
Then I see that I'd still need the toggle so that it will attach to the chainplate.
Does everyone agree this is the correct setup then?
Thanks for the introduction of riggingonly.com. As you can see I've been lurking a long time here, and just purchased a new-to-me Mariner 28 to sail Lake Michigan, upgrading from a 19' Prindle.
