Ella skiff nesting

Nested panels for the sailing Ella skiff

Readers interested in the sailing version of the Ella skiff may be entertained by this glimpse of how I’ve nesting all the various panels for the half-decked sailing version onto six sheets of ply.

I’ve placed the bottom, daggerboard and rudder components together because it seems to me natural that they should be made from the same 3/8in ply; the other panels I think should be in 1/4in.

Free plans are on their way. The next job is to plot all those coordinates for cutting out…

These drawings may not look like much, but actually they represent the next stage before I sit down to tabulate the plotting coordinates for building this little boat.

Anyone waiting for the drawings to be finished can be reassured that I haven’t forgotten this one!

Panels drawings and coordinates for the 12ft flat-bottomed Ella rowing skiff

[ad name=”intheboatshed-post”]

Ella skiff, panel plotting, sheet 1

Tonight, I’ve finally managed to find some time to make a little more progress on the plans for the stitch and glue flat bottomed Ella rowing skiff. We now have four drawings to show where the panels that make up this stitch and glue-built boat fit on three 8 by 4ft sheets and one 4ft by 4ft sheet of ply; and we have four tables of coordinates to enable builders to markout and finally cut out their material, create the necessary taped or butt-strapped joints  before beginning assembly.

I won’t explain how stitch and glue works here as there’s a lot of material available on this both on the Internet and in books such as my Ultrasimple Boatbuilding – the only thing I’d say is please don’t try the process without reading about it properly first. That way lies sticky madness, strange-shaped boats and epoxy glop that won’t go off, as at least some people have found in the past. Just check the forums…

Here are the drawings files you’ll need: Ella skiff plans.

A few warnings are required here.

Prospective builders should be aware that I am not a qualified naval architect and that my plans are amateur and experimental. I accept no responsibility for any injury or loss arising from building or using this boat and I urge builders and users of this boat to do so with care.

This boat is not for use on the sea or in any hazardous conditions. It is a small boat suitable for rowing on small lakes and slow-flowing rivers. It may be rowed but should not be used with an outboard of any kind unless the stern is doubled and otherwise reinforced. Even if that were done, it would be dangerous to use an outboard of more than 1hp. This boat is not designed to hydroplane and should not be made to do so – far too many fatal accidents occur each year beause some bozo thought it was fun or safe to put a large engine on a boat for which it was not designed.

I would also ask builders that if any coordinate creates a line that does not appear as it does in the drawings to contact me immediately. You may have found an error, and will need corrected measurements to be able to go forward. Also, I will want to correct anything that is wrong for the sake of future builders. In general, if you build this boat, please contact me at gmatkin@gmail.com. Especially with the first few boats built, I will want to be in close touch in order to ensure the boats are successful and the plans cause no problems.

These plans aren’t entirely complete – for example, they don’t show where the oarlocks need to go, or specify the gunwales or inwales – and I haven’t written my usual short essay yet. All of that will come.

Finally, if after all this you are still interested in building this small, simple and perhaps elegant little boat, I would strongly suggest that you build a model first! Read all about making a model here and here. There is also more on the Ella skiff design including the preliminary drawings here.

PS – It’s become clear that depending on your build, some folks will find the thwart a little high – if that could be you, it will be a very simple job to make the seat lower if you do so at an early stage.
