Lapwing 1816 Revenue Cutter

Thanks for those Bob, slowly piecing it together in my head but it's still mostly imagineering. -

Still going. Trying to work out the structure of the stern, very little info to work on. Any ideas? Any references? Re-did the frames to include decks, it will make life easier later. I wonder, what else am I missing. -

It's certainly not final but I should have pointed out that whereas the others are every second station, as usually depicted, that one is station 15, only a single step from the preceding station (14). It's a bit of a guesstimate to try to fill in the huge gap between station 14 and the transom. Same goes for the first station at the bow. If I could get out and buy some cardboard I would mock it up to get a better feel for the lines. But, thank you, all criticisms and suggestions gratefully accepted! -

G'day Tony, Actually, I didn't. I haven't delved very deeply into all the sisters, half-sisters, cousins and nieces, there's too many. Cutter then Schooner is the way I see it, the Cutter painting is dated 1840 and the sailplan 1841 so that works. I guess I will have to investigate Bramble further. -

I needed a break from staring at lines on a screen. Midship frame 1:24 in MDF. 1:24 is massive! 1:48 might be too fiddly for PoF for me, top timbers would be like matchsticks. -

Ok, new sheer plan based on the disposition of frames for Speedy (1828): Lots of work to go, all of these squares need to be filled (this is only stations D, B, 0, 2 and 4): -

Unless you compare it to the crews. -

Arrrrggggg!!!! Three steps backwards, after drawing up the frames at station 2 I remembered ZAZ6425 has two sets of station lines, then I realised that the sheer plan is based on station lines that have no relationship to frames. While this wouldn't matter for a PoB build I want these drawings to be able to be used for PoF. So I have to re-draw the station lines and sheer plan. Of course I don't have a table of offsets, but fortunately there is a shortcut I can take: By drawing a set of rectangles like the one in pink below, where points a and b are on the intersections of a station line and a reference line (in this case a water line) and point c touches the 45° degree line under the sheer plan, point d is the station line / water line intersection on the sheer plan. Unfortunately I don't have many reference lines on this drawing, basically just 4, so I have to base the shape of the 'frame' on those next to it. -
First they became a fence, did you notice the latitude of Macquarie Harbour? 42° South, that's roaring forties. You might like this one then, Port Arthur the main penal settlement. https://nla.gov.au/nla.obj-1961910992/view?sectionId=nla.obj-1965082829&partId=nla.obj-1961946782#page/n26/mode/1up

Ship building, Sarah Island 1832. The fence in the background is a windbreak the length of the island.

Apparently yes, I was aware of shipbuilding at Port Arthur but I assumed small vessels. It seems more likely that the 74 gun was probably built at Sarah Island in Macquarie Harbour on the west coast. http://www.ourtasmania.com.au/devonport/sarah-isld.html If I have it right, the shipyard was to the right of the bridge. A nearly completed Brig was stolen from there by 10 convicts and sailed to Chile but the amazing part is that they got it through 'Hells Gate' the entrance to Macquarie Harbour. https://viewer.slv.vic.gov.au/?entity=IE740422&mode=browse The entrance is just this side of the lighthouse.

Lower deck done (I think). It was interesting trying to work out the original Lapwing layout from under the revisions for Speedy, luckily ZAZ6347 for the Basilisk seems based on the original Lapwing. Somehow the squeezed 10 passengers in on the trip to Australia and I have a copy of an advert for 'First Class passage' -

Sail plan, just for something different. EDIT: Sailplan updated, now includes spar dimensions an a scale. Please let me know of any spelling or terminology issues. Lapwing Sailplan 1in48.mc.pdf -

A bit more progress. Deck almost done, just winches to do I think. I realise now that I should have drawn all those station lines and guide lines on different layers so I could turn them off, live and learn. -

To try to ease my headache I put together a list of plans relation to the Lapwing etc. I don't think it worked. Lapwing related plans.pdf -

Well, not an impossible fit. Agrees with some of the guesses I have made. But three different drawings have three different arrangements of the deadwood/keelson. And where did that trim on the transom come from? -

Excellent! Brilliant! There's a 43 in the top left corner, probably when copies were made by or for the Danes. Was there a treaty at that time I wonder? On ZAZ6507 you can just make it out as indicated, it's a bit clearer on ZAZ6377 which shows both a hatch and a deckhouse. I'm guessing he based his model on the drawings Bruce has provided. -

That was what I was referring to. The midship frame drawing seems to be taken from ZAZ6429 (1818) inking in the pencilled alterations. The deck plan has already given me some more clues, thanks again.

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
