Building 'Tamara':

This is a quick trip into the past showing the building of the steel hull, fit-out, launch and first sail. Some of the construction details may be of interest.

keel frames keel
The keel structure was built first, frames made from 5mm steel plate were set up on a 12mm keel base. The first course of shell plating has been tacked in place.
For ease of welding I added a tripod so the whole keel could be flipped which made welding a lot easier.
keel keel sunk
Here the keel structure is finished, all shell plating is welded up and the sterntube fitted.
The keel is placed into a pit to make construction of the hull easier - everything from now on has to be lifted up and this reduces the lift by nearly a meter.
internal structure station 6
With the keel forming a stable base an internal support structure was erected for the construction of the deck.
The forward part of the hull was to be framed up first starting with station 6
keel keel
The deck beams were fitted first, then the pre-manufactured bow section complete with stub bow sprit and lastly the flat bar stem. The frames were initially bolted to the deck beams and the floors so adjustments could be made during fairing, after which they were welded.
The aft section was extended from station 6 by adding coach roof sides and the cockpit and transom as individual units. All of those sections were prefabricated. Careful alignment was necessary especially the transom which at that point was free standing.
keel keel
The sheer line, where the deck and hull sides meet, is formed by fitting an L-shaped angle bent from 4mm plate..
The hull framing and sheer angle completed it was time to plate up the deck.. A ramp leads up to deck level.
keel keel
This is what it looked like with the deck structure complete, hatches and doarade boxes fitted.
Plating started at the bow, where full 1.22m wide sheets could be fitted, notice also that the full length of 2.44m was used for the first two sheets.
keel keel
The stern section having more curvature required cutting the sheets in half longitudinally. A light tackle was used to lift the plates.
This completed plating down to approximately waterline.
