Teak
Originating in South East Asia, Teak (Tectonis grandis) has been described as God's gift to boat builders. It is impervious to water and can tolerate brutal conditions that no other wood can survive. The wood is dense and oily to the touch and is described by some as having a slightly musty smell. Excellent for boat repairs for anything from steps to tables and fittings. Trees are girdled several years before the tree is felled to allow the sap to flow out enough to lighten the log for river floating. This species is becoming difficult to obtain in a reliable supply.
