It's finished!
I missed my deadline, but only by a few days. The finished product- not without its flaws- is below. Some of the lines sag, and I did my best to fix this, but sometimes I just couldn't get it to stay tight- particularly when it's fixed to something as flimsy as that modelspan. I applied superglue to keep it rigid, but it just wasn't straight enough. Next time, I'll know to use wire.
I took a few liberties with the anchor and with the lines from the corners of the sails running aft
Here is another place where I changed the configuration from that of the instructions, which insisted on fixing the lines coming from the sails be attached to the side of the ship at the lower part of the gundeck. That seemed an awfully long way down and a huge trouble in the case of changing sail, so I looked at some more pictures. Most of these showed the same lines being fixed to the ship much higher, so I tried to emulate that.
I was short on time, but I had to find time to at least add the lines going from the main yard to the stern. But, believe it or not, this wasn't in the instructions. So I looked at some pictures of other models and of the Surprise/Rose and made my own approximation with one of the extra pieces from the kit.
The kit also didn't specify that the corners of the topsails should be fixed to the main yards, though this was evident in pretty much every picture I saw. So I fixed that too- it took little enough time.
This is probably the weakest part of my model, and close examination will show that one side is slightly different than the other in the way the foremost anchor is lashed to the ship. I was having trouble finding a definitive source on how this should look, and again I was out of time. So I took an illustration from A Young Officer's Sheet Anchor, which seemed minimalistic, and added a couple more lashings as I had seen in many other pictures of models. The result is probably somewhat dubious, but I doubt the recipient will notice or care, thankfully. Next time, I will definitely have to do more research, though. Oh, I did add puddening though! Something I had not been familiar with.
All in all, I am thrilled with my model, flawed (very flawed, though that is mostly due to the instructions) rigging and all. I thank everyone here for their advice and encouragement, and I can't wait to push myself a little further and try something more in-depth (and maybe on a larger scale lol) that will have more detail and be more accurate.
And any critiques are welcome. As we in training (my current profession) say, "feedback is a gift."
