Abstract: Systems and/or methods for establishing and maintaining authenticity of a plurality of records and/or documentary materials to be persisted in an electronic archives system are provided. Each record and/or documentary material may be safeguarded throughout its entire lifecycle by monitoring and recording both intended changes to each said record and/or documentary material and its corresponding status, as well as unintended changes to each said record and/or documentary material. Context and structure associated with each said record and/or documentary material may be extracted and preserved. Substantially uninterrupted proof-of-custody including at least a source may be established and preserved for each said record and/or documentary material throughout its entire lifecycle. Essential characteristics of each said record and/or documentary material may be captured and preserved throughout its lifecycle in dependence on one or more changeable definitions of essential characteristic.

Abstract: A moulded boat hull is disclosed which includes a modular liner which is nested within and hermetically sealed to a hollowed moulded plastic boat hull structure. The liner includes the seamless floor section of the boat, which is supported by stiffening members within the boat hull. Substantial flexibility is achieved by permitting the use of alternative liners within the same boat hull, thereby allows customization of the boat.
