Retrieved from the Data Repository for the University of Minnesota, https://doi.org/10.13020/hb2d-1721. -------------------- DATA & FILE OVERVIEW -------------------- The wake waves heights of four test boats (i.e., Larson, Response, VLX, MXZ) were measured via sensors attached to either masts or pads [Wake Wave Data.zip] at multiple boat operational distances [Boat Operational Distance.zip] To determine the boat operational distances two data sets are required 1)[Boat Positional Data.zip] and 2)[Mast_Pad Locations.xlsx] The [Timelogs.zip] data is needed to pair the times between boat positional data and wake wave data Data-specific information for: Boat Positional Data.zip ------------------------------------------------------------------------------------------------------- Each boat made four runs along track lines at 225, 325, 425, and 625 ft from shore under three operating conditions (i.e., C1a, C1b, C2) 1. Number of variables: 25 2. Number of rows varies depending on length of data recording (i.e., time it took to complete a run) 3. Variables used from this data set = 2 K. Name: Lat Description: the latitudinal coordinate of the boat L. Name: Lon Descriptopn: the longitudinal coordinate of the boat Data-specific information for: Mast_Pad Locations.xlsx ----------------------------------------------------------------------------------------------------- The mast locations were the same for all test days/boats. The pad locations changed for each test day/boat. 1. Number of variables: 3 2. Number of rows: 5 3. Number of tabs within document: 4 - one for each boat 3. variable list A. Name: Station Description: identifies what structure (i.e., mast or pad) the sensor is on B. Name: Latitude Description: the latitudinal coordinate of the station C. Name: Longitude Description: the longitudinal coordinate of the station Data-specific information for: Boat Operational Distance.zip ------------------------------------------------------------------------------------------------------- The distance measured between each boat pass [Boat Positional Data.zip] and the locations of the sensors [Mast_Pad Locations.xlsx] 1. Number of variables: either 5 or 6 depending on if you are looking at the Masts or Pads tab 2. Number of rows varies depending on how many passes/runs were completed for the boat 3. Variable list A. Name: Condition Description: boat operational setting (i.e., C1a, C1b, C2) B. Name: Pass Description: the pass number (1-4) along the track line C. Name: Distance f/ shore Description: the distance from the track line to shore D. Name: Distance to Mast or Distance to Pad (ft) Description: the distance from a boat pass to either Mast C or the 22 ft pad depending on which tab you are on (i.e., Masts or Pads) E. Name: Distance to Mast or Distance to Pad (ft) Description: the distance from a boat pass to either Mast B or the 14 ft pad depending on which tab you are on (i.e., Masts or Pads) F. Name: Distance to Mast Description: the distance from a boat pass to Mast A Data-specific information for: Timelogs.zip ------------------------------------------------------------------------------------------------------- These are the time stamps of the individiual files created for each boat pass in the [Boat Positional Data.zip] files. The hours, minutes, and seconds are converted to minutes from midnight. 1. Number of variables: 7 2. Number of rows varies depending on how many passes/runs were completed for the boat 3. Variable list A. Name: Condition Description: boat operational setting (i.e., C1a, C1b, C2) B. Name: Pass Description: the pass number (1-4) along the track line C. Name: Distance Description: which distance the pass occurred at D. Name:Hour Description: hour the pass occurred at E. Name: Min Description: minute the pass occurred at F. Name: Second Description: second the pass occurred at G. Name: Time (Min) Description: variables D, E, F converted to minutes from midnight Data-specific information for: Wake Wave Data.zip for the four boats (i.e., Larson, Response, VLX, MXZ) ------------------------------------------------------------------------------------------------------- Each boat zip file includes .txt data from the sensors at either the Masts (A,B,C), Pads (14ft, 22ft), or both.
