This paper describes a part of the Yacht Captain Training system, particularly the part that includes ships and scenes modelling. It is divided into two parts. The first deals with problems of practical usage of VRML standard for basic 3D modelling, while the second inquires the possibilities to make virtual sailing more realistic.

Computational simulation isan important tool for predicting the behavior of physical systems. Many powerful simulation programs exist today. However, using these programs to reliably analyze a physical situation requires considerable human effort and expertise to set up a simulation, determine whether the output makes sense, and repeatedly run the simulation with different inputs until a satisf...

This report describes a fibreglass mould maker in the yacht building industry who developed a deep vein thrombosis (DVT) after 6 weeks of working in a kneeling position. We propose that his prolonged kneeling combined with constrictive knee pad straps caused vascular compression, precipitating his DVT. A hypercoagulability diathesis was suspected but not confirmed. Operator and employer educati...

lent, considered by many to be one of the best sailing areas in the country, provided an opportunity not to be missed. Although my initial trip out was in a yacht, most of my early experience was in dinghies less expensive to buy and to repair if damaged. The first dinghy I shared was with three other equally inexperienced friends. We bought a 14 foot fibre glass family dinghy through Exchange ...

Welcome Bay and Chaguaramas Bay in the northwest peninsula of Trinidad contain large marinas and smaller sections of bathing beaches. Bacteriological surveys were conducted at both bays to assess water quality and to determine potential sources of pollution. These surveys were conducted during the wet season of 1996 and the dry season of 1997. Eleven sample stations were established at Welcome ...
