To meet the need for accuracy of the surface speed measurement, the mechanical sensor paddle wheel has been replaced by the ultrasonic sensor. This ultrasonic sensor measures the water speed precisely and with very good linearity. Furthermore, by its principle of operation, it measures the water flow several centimetres from the sensor, which puts it outside the boundary layer, the region close to the hull where the flow is disturbed. However, this sensor has several drawbacks: it is quite sensitive and if the flow contains too many air bubbles, the sensor picks them up, which can happen quite frequently on boat with a planing hull. Another limitation of this sensor is its low frequency measurement rate. In this paper, we explain the techniques used based on Kalman filters to address these shortcomings, firstly by identifying the inaccurate measurements caused by inadvertent dropouts, then by improving the useful sensor frequency with GNSS data fusion.","PeriodicalId":355970,"journal":{"name":"The International Journal of Small Craft Technology","volume":"36 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123395659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was accepted worldwide and many of the famous yacht designers of today made their name in the high profile events that took place under this rule. There is a large body of commentary and opinion regarding yachts of this era, in which the rule allowed the designer to explore the design space in search of designs that rated lower than their size. Yachts, particularly in the early IOR era, were designed through experience, knowledge of the rule and inherent talent. Computing power was low and the subject of velocity prediction was in its infancy. This paper examines a method of undertaking a velocity prediction of yachts of this era using data provided by the designers, namely lines plans and rating certificates. A performance sensitivity analysis is conducted examining aspects such as measured versus sailing trim, lack of geometric data, influence of waves and sail configurations. The results show that subtle changes in input data, associated with the yacht, can be measured in terms of performance. This will allow for the future comparison of fleets of boats and provide some data to confirm or contradict the sailing community narrative regarding IOR yacht performance.","PeriodicalId":355970,"journal":{"name":"The International Journal of Small Craft Technology","volume":"128 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123574820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
