Not sure of that Norman, certainly the Massey Shaw (the biggest one) was convention build.
Steve, solution to the 'man inside problem' Inflate a large balloon in there before you start the rendering :lol:

Just give the gogo girl a trowel!

They don't use expanded metal lath on ferrocement boats to my knowlege -- usually they use multiple layers of chicken wire and/or metal mesh over a complex wire armature. That's more permeable.
In this tank one layer of chicken wire goes outside and expanded metal lath goes on the inside and is fairly "opaque" to the plaster. Cups face up. Worms of plaster do squeeze through, but a rough surface is a benefit for keying a second coat. The inside is plastered first, then serves as a backing to the second coat outside. A third coat goes inside. That's for a tank. Boats are plastered at one go. Boats are relatively thin skinned for the volume, but exposed to high seas and gales, as well as mast and keel working stresses. A tank is stationary and weight and thickness isn't a penalty.
One section has fewer horizontals to allow a temporary narrow acceess. It is closed and plastered up as late as possible. A permanent ladder is built into the tank for maintenance and safety.

Naturally I barely got 2 horizontal rings bent and wired on temporarily today when it started to rain. :bang:
I think it's starting to look more like it would have a darede\vil on a motorcycle than a 60's wood nymph inside.
