📝 Cigarette hull (Kingston Mouldings)

Hi there shipmates,
'Nut Screws Washer and bolts', yes there're all in the transom now.
Had to put the bolts in backwards for the turn fins as the space restrictions inside made it near impossible to use a spanner or box spanner inside the hulls stern.
Added side panels to the cockpit area. Build in seat started, not shown but reinforced rear access compartment.
Regards
Roy
P.S. the rudders are vertical it's an optical illusion caused by my camera!

Hi there shipmates,
Due to the propeller shaft spacing of 41 mm apart, I had to make a engine mount, and angled it to a line the two flexi shafts with minimal bending.
I will not cut the flexi shafts until I fit the two contra rotating propellers, that are on order. 2x 40mm diameter x 18mm pitch.
Starting on the cockpit area, I lined it with wood and built a seat also from wood, waiting for some bolts before mounting the rest of the hardware to the transom.

The CD's look good but there may be a skip in them when played. LOL
Good looking build so far. Can't wait to see where the design takes us. Rick 👍 Like

Holy Disco,
Is it a bird, is it a plane, Is it a CD player!
I thought I would give every one a laugh, at my boat build, yes be careful with expanding foam as it expands up to 6 x it's initial volume.
I not going to tell you what it is going to be.
It is not going to be a Classic Cigarette hull, or a CD player.
Removed some more wood from the original frame the cabin would have sat on, added plastic pipe. reinforced and glued then foam filled, CDs were the right size for the job.

Roy

Roy,
I like the use of the cd's! Great thinking.... Amazing how that foam expands, I've only used in in building construction. Tough to predict! Joe 😎 👍 Like

Hull preparation filling imperfections, undercoat hull, drill for transom two rubber bellows for servo linkages.
Received second ESC but still waiting for the two water jackets, before I install the flexi-shafts and bend them to shape.
Also filled old Ariel position and the old water outlet position.
TIP when bending a flexi shafts outer tubing, fill it with compacted salt, sugar or sand two prevent kinking.

Had a smashing time removing excess wood, to increase access to rear of the hull, and a picture of how it was before, also a picture of one of the motors and mount.

Hi there,
Just received my second rudder through the post, have now modified both so they will lift up if hit a branch or other obstacle in the water.
Also drilled the tiller of the rudder so linkages will be symmetrical out of the transom. similar to the orange boat pictured.

If the rudders lift up do they go back in place I'm interested .

Hi Rick,
I think it unlikely, they may fall back down partly, mainly it is to stop you ripping your rudders out the transom if you hit a tree branch floating on the water. Added two pictures of a commercial rudder. Regards Roy 👍 Like

Hi All, (Please note pictures not in order)
Added pads for twin rudders and some imitation exhausts.
More complications, after checking the Hull for straightness (Using edge of a ruler, see light under it.) I found that the boat had a hook (Indent in the hull) so thought had better sort it now rather than later.
Started by removing some material from the transom area under the hull, then keyed the area for the addition of a thin layer of plastic padding, then spent a hour or more sanding it off.

Holey transom, Batman (clue) next problem with the transom is that it is inclined and not square with the hull bottom.
so pads made for the stingers to bring them square at the transom.
Ideally they should nominally be set at 1 degree down into the water. and adjusted according to the characteristics of the hull's planning at speed.
Will also need to add pads for the rudders and trim tabs!

It's good you have a grasp of how to build the cigarette boat .I would be lost at just trying to get started let alone figuring our the transom angle trim tabs and rudders .I look to keep reading as I may understand what you are doing.

Hi Newby7,
I do not how to build a cigarette boat just basic RC speedboat theory. a Cigarette boat as per picture has twin props close together near the lowest part of the hull normally inboard/z drives or outboards. There is a problem with this configuration in that when cornering a mono hull leans over onto one chine and one prop may come out of the water. Luckily you will not have this problem with you single propeller IC engine. As I cannot afford a model z dive so I settled for a pair of stingers £9 each and electric motors (as many places do not allow IC engines) When you put in your drive train have a word with Prestwich for advice about surface/ subsurface drives, straight or flexi drives and recommended props. see pdf of mono setup it may be of interest! This is a fast well setup Cigarette boat video https://youtu.be/vX4suCvlAww Regards Roy 👍 Like

Wholey transom, Batman (clue) had fun drilling holes in the reinforced transom, and as luck would have it, when I stuck the lump of wood in, I failed to see a small nut that was glued on the inside surface, from the previous installation.
So I was Drilling for gold, no I mean for the Hardware and I hit this beep beep nut trapped between the transom, had to drill it out by force through the ply reinforcement, a smell of burning wood and it was out.
Now have added filler to the area, and will re-drill when cured.

Roy

I am about to start a 39" Dry Martini Offshore vintage project. Had the stuff for 20 years but life got in the way of it.
Got an SC .61 going in it with Prestwich Models surface drive hardware and tabs. Mate of mine has a sign shop with a vinyl printer/cutter so he's going to be busy making all the decals for me. 👍 Like

Looks like a great project , the artwork can be difficult to match, but your mate should be able to sort it.
The trouble with my hull is it is not to scale and the superstructure is non cigarette. It would take a lot of work to get it right, so I am going in a different direction with this hull it should be fun. 👍 Like

Hard ware
I have used some of this hardware before on other boats but thought I would like to try dual stingers, will be ok for straight speed (not a class racing boat), will it turn, that is to be seen?
:-
2x 3674 2250 kv will run at 14.4v
2x 150A esc
2x flexi drives one ccw one cw
2x coupling
2x stingers
2x rudders
plus one pair of turn fins and props
Has been done before.
