I don't want to get into another lengthy discussion about this kit; I've said what I have to say about it, and I can't imagine that anybody wants to hear any more from me about why I don't like it. I have, however, always emphasized that I don't intend my low opinion of it to stop anybody else from building it. This is, for most of us, a hobby; what matters is the individual modeler is attracted to the subject. I do think the modeler is entitled to go into a project with eyes open; if I'd known, back in 1974 (or whenever it was that I bought the thing), how inaccurate it was, I wouldn't have bought it. But the modeler who, having read all the comments about it on other threads, wants to build it certainly has my best wishes.
Regarding waynec9436's specific questions - the matter of belaying pins (and belaying points in general) is a little complicated. The belaying pin certainly was in use by the Soleil Royal's day, but apparently not nearly as common as a hundred years or so later. On one of the other threads it was noted that the deck furniture of the Heller kit probably is pretty inaccurate; there almost certainly ought to be more bitts, cleats, pinrails, etc. than there are. And it seems likely that some of the bitts and rails would have had belaying pins in them. In any case, replacing plastic pins with brass ones is always a good idea. (And belaying pins do not have sharp points.)
I've seen quite a few different ways of rigging portlid tackles. Sometimes there's one line running from the middle of the bottom edge of the lid. Sometimes there are two, running through two holes in the hull. Sometimes there are two eyebolts in the lid, with a Y-shaped tackle between them and its "stem" running through a single hole in the hull. There usually were two eyebolts (or ringbolts) in the bottom/inside of the portlid, for the purpose waynec9436 mentioned.
One thing I've been curious about for a long time is just how the portlids were kept closed. Presumably there was some sort of tackle rigged to those eyebolts, but I can't recall having seen a picture of it. I have seen, somewhere or other, a drawing of a simple latch mechanism -similar to the modern sliding door bolt - but that was (I think) on a nineteenth-century ship. John Harland's wonderful book, Seamanship in the Age of Sail, shows a gadget that, he says, was used to secure a gunport lid during a storm. It consists of a wide board with two elongated slots in it. The slots are slipped over the eyebolts in the portlid, and an iron rod is shoved through the eyebolts.
That's the best I can do with those. Good luck.
