Looking at it this way I think the rear foil mounts to the same ring as the foot brace. The support for the steering column mounts to the next ring, the board extends from the end of the steering column to just aft of the seat, the foil is also wider than the earlier one. Greg, note the flag in the pic you posted, probably for signalling the tow boat. Still guessing though.

Thinking about it, the top one may have been a prototype and may even have been towed.
-
It looks like he made modifications in that area: It looks like there were two different variants or something. Anyway, in the top pic the hydrofoil mounts under his backside and in the bottom pic it mounts approximately under his knees. (I think).

Double banked versus single banked ships' boats
-
Steels tables break down in to SWEEPS, OARS and SCULLS: As you can see from the inboard length compared to the breadth he hasn't included oars for double banked boats. The sculls would fit but they are for one rower with two oars. Double banked oars should (I think) have 10" handles, a total inboard length of under half the breadth and be shorter than single banked oars. NOTE: The button is 2" down the body so has been added to inboard and subtracted from outboard. The rows in red don't add up to the sweep.
-
Certainly, but the boat is fitted with as a hybrid rowing system. I suspect it was something like preventing resentment of the rest of the crew if the bowman was carried around like an Admiral. ¯\_(ツ)_/¯ ------- Anyway, I thought trying to nail down terminology might be worthwhile. I think this is how it goes: Starting with OAR, basically every paddle worked against a fulcrum (THOLE) is an oar. Oars are broken down into two types, SCULLS and OARS. (there is also SWEEPS which are 'larger OARS' used on ships or boats). SCULLS are operated by one man SCULLING with one oar over the transom or one or more men operating two oars each on the one thwart (also called SCULLING). OARS are operated over the sides of the boat by one or more men per OAR. They can be single (one oar per thwart) or double banked (two oars per thwart), single banked would tend to use SWEEPS. Operating a boat with one or more men per OAR, with the oars over the sides, is known as ROWING. To add to the confusion, an OAR operated over the transom could be called a SCULL if used for propulsion or a SWEEP if used for steering. And SCULLS and OARS were also the two types of "water taxis" used on the Thames. Maybe.

I came across this pic of Police on the Thames which opens a new can of worms:

This is what I can come up with for pinnaces:

Why do many modern ship's boat models show gratings instead of platforms fore and aft
-
Which of course is the correct attitude. I've looked at a lot or drawings and contemporary models to see what the options were: Fordeck: Gratings Planks athwart ships (across the boat) with or without gaps. A single plank athwart ships. Longitudinal planks with or without gaps. Chevron Planking (^) with or without gaps pointing forward or pointing aft. Generally the 'quarterdeck' is planking without gaps, occasionality a grating. And as usual, there will be exceptions.
-
The problem is a lack of standards. There were no drafting text books so it was a case of doing as you were taught. Some drawings such as the one above may, for example, depict a half hull model while others the whole boat. When depicting the whole boat, sometimes objects the far side of the centreline are drawn dashed, sometimes solid. Sometimes extra details are depicted on the half breadth, sometimes not. Ultimately these drawings are not the engineering drawings of today, they are general guides backed up by scantling details and contracts which we rarely see. Or the might be right, but I don't think so.

Alfredo, it has little to do with the number of planks, it is about the shape. (although narrower planks are easier to bend sideways). The kit planks are rectangular, mine are shaped (a bit like a ski, see the photo) to fit against the previous plank. This process is called 'spiling'. Spiling can be simulated by 'edge bending', forcing a plank to bend sideways with the use of heat, but wood doesn't like doing that. I find cutting the plank out of a wider piece of wood easier.

Bounty Boat by AlfredoCampos - OcCre - 1/24

G'day Alfredo, I think that, given you were trying to do 'correct' planking with the wood supplied, you've done quite a good job. First, a reminder that your planking is quite thin (I think 0.5mm) so it can't stand much sanding, go easy. For any very low areas try gluing another layer of planking over the top of the low area (matching colour and grain as best you can) then sanding it down to blend it in. This is so you don't sand too much off adjacent planks trying to match the low area. A little glue applied with a pin in the holes and gaps then a light sanding to get sawdust into them will help, do one at a time and repeat if you have to. Only after you are happy with your fixes, lightly sand the whole hull.

Probably a bit late but this is the general arrangement drawing of the controls of a Pup which would be very similar to that of a Camel.

HMS Bounty Jolly Boat by Peter S - Artesania Latina - 1:25 First Boat Build

G'day Peter, I found this description on another site, The goal of hull fairing is to bevel the edges of the bulkheads so that the hull planks lay flat. If we didn’t do this, the planks would only hit the corners of the bulkheads. The problem is it only tells a part of the story. The aim of fairing is to have a finished hull with nice flowing lines, without lumps bumps hollows or kinks. Simply bevelling the frames without considering this only allows a greater gluing area, which although important, is only part of the story as I said. Your plank (or batten) should sit naturally against the intermediate frames if held down a few frames apart. Looking at your second pic you would probably have needed to sand the areas indicated below. But only enough to allow the plank to fit.
-
Yeah, that's a one man boat, two at a pinch. Below is Lapwing/Speedy, close enough to Cheerful. The blue outlines are 16' cutters the green 18', the orange a 20' Gig and the pink a 22' Gig, more or less. At a pinch (and in utter desperation) I think a 16' cutter could carry 10 passengers and 2 oarsmen, in a dead calm for a short distance, or more realistically 6 passengers and 2 oarsmen (or 4 and 4) and is I think the biggest I'd put on stern davits. For an 18'er, maybe 4 more (10) but you'd need 4 oarsmen (so 10 minus 2) so only a slight gain, a 20' Gig another 4 more (14) and still 4 oars, a 22' Gig another 4 more (18) but 6 oarsmen (so 18 minus 2). All this assumes a minimum of oarsmen to allow more space for passengers and is just a guess.

Sure does. I'm far from being familiar with UK timbers but I'd look at Ash. You want something that looks like a de-barked tree (in miniature).
