Thank you Prof. Tilley for bringing some sense to the matter with your experience. As an Imai mold it seems worth adding to my Viking "fleet". Coming from a Norwegian family (my grandfather went to sea at 12 on a sailing ship) our house was graced in the 60's by the Aurora model,and it's nice to be able to add more accurate models to it. I am one of those returning to the hobby after many years, and I'm doing my research before I tackle both the Emhar and Revell.
I'm a little hesitant to endorse the old Imai kit whole-heartedly, for the simple reason that I haven't seen it outside the box in many years. It isn't easy to produce a good scale ship model on such a tiny scale. I wonder just how delicate the oars are, for instance. The oars of a Viking ship model can make or break it - and replacing them would, due to the sheer number of them, be quite a project.
I'm a big fan of the old Revell kit. It was originally released (according to Dr. Graham's book - which I trust in such matters) in 1977, and was the last genuinely new sailing ship produced by Revell of the U.S. (as opposed to Revell Germany, which has released a few since then). Revell got into the sailing ship genre with its original U.S.S. Constitution in 1956; the company has now been out of the game longer than it was in it.
I don't know how many times I built that old Aurora kit - starting when I was about eight years old. It has a special spot in my memory - and I'm sure it was responsible for introducing thousands of people to the joys of ship modeling. But as a scale model...well, it just plain isn't a scale model. The designers apparently did no research whatsoever; they just whipped up something that matched the 1950s American conception of what a Viking ship looked like. (It doesn't have a clinker-built hull. It does have permanent benches for the rowers - which none of the surviving Norse ships do. There's no sign of the delicate, graceful sheer line that's so characteristic of Viking craft. The "dragon head" on the stem, in addition to having a distinctly non-Norse character, would have been impossibly big and heavy. And some of the guys walking the deck have horned helmets. One of the first things one learns on getting serious about the subject is that the horned helmet is not part of Norse culture. Wagner operas yes; Vikings no.)
You probably already know this, but the essential source of reference for any Viking ship model is The Viking Ships: Their Ancestry and Evolution, A.W. Brogger and Haaken Shetelig. It contains reasonably detailed plans of the Gokstad and Oseberg Ships - the two biggest surviving Viking vessels. (The book is long out of print, but I found a used copy on the web for about $15.00.) Those plans of the Gokstad Ship make the Revell kit look pretty good. It has the right number of planks on the hull, all the deck planks are laid out exactly right (despite the fact that, in the real ship, they're just pine boards laid loosely in rabbets cut in the tops of the deck beams), the oars are just right (and come in three different lengths - just like the real ones), and all the detail parts - the shields, anchors, rigging blocks, etc. - match artifacts that were found in the real ship. (The big exceptions in that regard are the bow and stern ornaments. The stem and stern of the real Gokstad Ship projected into a more acidic layer of soil in the burial mound, and whatever decoration was on them was eaten away. The Revell parts are speculative - but at least they're consistent with other Norse artwork.) The biggest problems with the kit, in terms of accuracy, are errors of omission. A few small components are missing (the scallop-shaped trim pieces at the bow and stern, and one little bulkhead), and the knees connecting the deck beams with the hull halves aren't there. (On my model I fixed them with Milliput epoxy putty.)
I was about halfway finished with my model (based on the Revell kit) when the new Emhar kit was announced. I haven't seen it in the flesh, but on the basis of web photos it seems to be an excellent kit. The Emhar people seem to have included considerably more detail below the deck (offering the option of leaving some of those temporary deck planks off), and apparently did a much better job with the deck knees. On the other hand, Emhar apparently didn't make any attempt at a "wood grain" effect on the planking (The "wood grain" in the Revell kit is excellent. In fact it looks remarkably like the "wood grain" on various Imai kits. One does wonder....) At any rate, I'm pretty satisfied with my model. If I were ever to do another one...well, I'm honestly not sure whether I'd pick the Revell or Emhar kits. It's nice (and, in the plastic sailing ship world, unusual) to have two good kits to choose from.
There's quite a bit of interesting stuff on Viking ships, and models thereof, here in the Forum. This page would be a good start: /forums/t/102174.aspx?PageIndex=1 .
Good luck.
