Emerging in the later neolithic and bronze ages were the plank boats

It enabled larger vessels for more secure open sea travel. Using more complex rigging and for cargo transport

1) Materials and resources had cedar (cedrus libani), pine and oak in the Levant. Cedar became a strategic export;
Anatolia had oak, pine and juniper; and,
Greece had pine, fir and oak
It became linked to islands (shipwrecks) and trade networks
Egypt also had limited timber, acacia, sycamore fig (short planks) but traded and was on a large river
Loggers would fall trees with stone axes, and fire, whatver they could. And, bronze, copper, or metal axes later. The logs could be transported by pack train, river floatation, or sledges.
Because of its use mechanisms, timber was often state or elite controlled. Such as examples from the Levant and Egypt

2) Tool kits
Adzes were used for shaping; axes for felling, rough shaping; chisels and gouges; bow drills for holes; and, sand and stone for polishing.

3) Joinery technology included mortise and tenon. Planks were joined edge to edge, pegged or lashed into place.

Sewn plank construction included holes drilled along plank edges. And, stiched together with fibre cord.
Lash-lug systems included internal lugs carved into planks. And, ropes tied through to bind structure.

4) Construction was commonly a step by step process. Beginning with the keel or base assembly. Some boats were flat bottomed, others with proto keel/plank. Plank shaping took split logs into boards, where they could then be shaped with adzes, and smoothed for a tight fit
The hull assembly joined planks edge to edge. Commonly built shell first (the outer), with internal supports later
Internal framing included frames and ribs inserted after hull was formed. Crossbeams and thwards meant reinforcement, durability and strength
Caulking materials such as plant fibers, pitch, resin and bitumen could then be used. Essential for water and weather proofing, durability and armour
Structural engineering could have included hull design features like curves. Reinforcements for the bow and stern. Internal bracing systems and hogging trusses like a rope tension system to prevent hull saging

5) Double and multi hull concepts helped with larger loads and stability

6) Sail systems were already being developed across regions. Most documented in Egypt with the square sail on a central mast. Rigging included rope or lashings from flax, papyrus fibers, hair. And, they probably had rudders, and/or paddle systems

7 Quality control like wood selection, plank thicknesses and accuracy of measurement was important. Regular inspection was also credited for moisture control (and, thus strength) of wood. For operational control and load balancing. Environmental awareness like seasonal sailing, coastal navigation and storm maps was noted
Common failures: joint separation, hull leakage warping/splitting planks, rigging failure or mast collapse. Included repair methods such as recaulking seams, replacing planks, tightening lashings, reinforcing joints with additional pegs
Testing included water trials in calm conditions, leak detection, load testing and performance evaluation. Including handling under sail, in waves, speed and maneuverability and combinations checks

Plank boats were trade-driven production. Levant being a major innovation hub because of species; Egypt and other sites being on a river or lake for log and timber flotation. And, others trade, or near mines or resource extraction

Though they requred more organized joinery, labour and quality control systems. Plank boats enabled longer more reliable distance maritime trade for exchange of: metals, timber, ceramics and other resources.
