Interesting. But the problems with the Heller kit's spar dimensions go beyond the basic measurements.
The big offenders, to my eye at least, are the topmasts. When the spars of a ship are set up, the first things that go into place are the lower masts. When they're safely located, and the lower shrouds and stays are rigged, the topmasts are hoisted into position. The topmast has to be stood on the deck in front of the lower mast and hoisted up through the top (the platform at the lower masthead). In French ships of that period (as Heller more-or-less correctly represents), the topropes (the heavy lines used to hoist the topmasts) were left set up all the time. (English ships only seem to have rigged them when the topmasts were being hoisted or lowered.) The toprope starts from an eye under the lower mast cap, runs down through a sheave at the foot of the topmast, then runs back up on the other side and around a big wood sheave in the after part of the cap. (The big hump in the back part of the cap is a characteristically French feature.) Then the line goes down to the deck. The arrangement is repeated on each side of the mast. Haul on the toprope tackle and the topmast goes up. Slack off on the tackle and the topmast comes down. "Striking the topmasts" was a fairly common evolution in bad weather, and whenever some piece of upper rigging needed to be replaced.
The problem with the Heller kit is that the topmasts can't be hoisted or struck, because they're too long. When the lower masts are mounted, the distances between the tops and the decks are shorter than the lengths of the topmasts. I'm not sure whether the lower masts or too short or the topmasts are too long; I strongly suspect the latter. At any rate, the overall assemblage just can't work.
Neither can those big, bulged plastic parts that are supposed to be glued onto either side of the topmast heads, for the topmast crosstrees to rest on. The topmast (except its very foot) has to be small enough to fit through the hole in the lower mast cap, or the topmast can't be removed (or, for that matter, installed).
The spars of a square-rigged ship are built and rigged in such a way that the uppermost ones can all be removed without disturbing the "layer" below. The topgallant masts can be struck without interfering with the topmasts or their rigging, and the topmasts have to be shorter than the lower masts (minus the portion of the lower mast between the keelson and the uppermost weather deck) so the topmasts can be struck.
This is one of the many reasons why I so strongly dislike that kit. You just can't design the spars of a scale ship model without understanding how the prototype works - and the Heller designers clearly didn't. Over the next few years somebody clued them in and for their next big-scale project they picked a ship for which plenty of detailed, reliable drawings and measurements are available. The spars of the 1/100 Victory kit are fine.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
