Evaluation of methods for estimating power to the most common form of hulls in the Amazon
Evaluation of methods for estimating power to the most common form of hulls in the Amazon
The Amazon region has had only a few studies in the field of naval architecture. This paper will explore the design of specific craft suitable for this environmentally sensitive region. The design will require verification and validation of the computational methods used to assess the hydrodynamics of the typical vessels commonly used in the Amazon region. This research presents estimation methods for power boats, where one seeks to compare several statistical methods, based on systematic series and methods which use finite element theory with the results obtained from experiments performed in the towing tank. For the validation of the power estimate it is necessary to compare the results generated by these methodologies with the results obtained in tests with scaled models in a towing tank. An identification process was used to determine three typical types of regional powered vessels on the Amazon. The effective power was then analysed for these vessels. After selecting the type of hull, ship models were constructed for testing in the towing tank. Comparisons are then made between theory and scaled models

Abstract
The Amazon region has had only a few studies in the field of naval architecture. This paper will explore the design of specific craft suitable for this environmentally sensitive region. The design will require verification and validation of the computational methods used to assess the hydrodynamics of the typical vessels commonly used in the Amazon region. This research presents estimation methods for power boats, where one seeks to compare several statistical methods, based on systematic series and methods which use finite element theory with the results obtained from experiments performed in the towing tank. For the validation of the power estimate it is necessary to compare the results generated by these methodologies with the results obtained in tests with scaled models in a towing tank. An identification process was used to determine three typical types of regional powered vessels on the Amazon. The effective power was then analysed for these vessels. After selecting the type of hull, ship models were constructed for testing in the towing tank. Comparisons are then made between theory and scaled models
