N2 - A potential-based boundary element code called AEGIR was evaluated for bare hull resistance predictions of different hullforms including the Joint High Speed Sealift (JHSS) monohull, a catamaran, a trimaran and a hard-chined semi-displacement monohull. Two different bow configurations, an elliptic bulb and a gooseneck bulb, of the JHSS monohull were considered for bare hull resistance. Measured data from model tests was used as a benchmark for the assessment of AEGIR results. The correlation between AEGIR and model test results for calmwater performance (Resistance, Sinkage and trim) was excellent for the JHSS monohull configurations but was poor for other hullforms studied. The results are inconclusive for seakeeping assessment due to limited number of studies. The overall conclusion is that AEGIR performs well to predict calm water and head sea seakeeping performance for hullforms with small or no transoms.
