Designation F3099 − 19Standard Practices forParasailing1This standard is issued under the fixed designation F3099; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon ´ indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice provides guidelines and procedures for theoperation, maintenance, and inspection of parasail vessels,equipment, and associated activities including crew trainingand flying passengers aloft in a parasail.1.2 UnitsThe values stated in inch-pound units are to beregarded as standard. The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade TBT Committee.2. Referenced Documents2.1 Federal Regulations246 CFR Part 16 Chemical Testing3. Significance and Use3.1 The purpose of this standard is to establish proceduresfor water based parasailing activities.4. Weather Monitoring and Limits4.1 Vessels used for parasailing operations shall beequipped with a weather monitoring device.4.1.1 The device may be fixed or portable, provided it isaccessible by the vessel Master at the vessel’s operatingconsole.4.1.2 The device shall be electronic with a visual display.4.1.3 In restricted locations such as manmade lakes, theweather monitoring device, under 4.1, may be located withinthe immediate proximity of the operating area provided it iscontinually monitored by a company employee available toprovide updated weather information to the vessel Master viaradio or cellular phone.4.1.3.1 A VHF radio, alone, is not acceptable for weathermonitoring.4.2 The vessel Master shall check and remain cognizant ofcurrent and forecasted weather conditions for the area ofoperation and account for the weather conditions for theduration of the parasail set the “onboard” group of passengerson a parasail vessel.4.3 Weather LogThe vessel Master shall maintain aweather log.4.3.1 Log entries shall include wind direction, wind speed,wave height, and sky conditions. A sample weather log isprovided as enclosure see Appendix X1.4.3.2 A weather log may be in any format with the weatherinformation recorded manually or electronically.4.3.3 A legend shall be provided for any coded or abbrevi-ated log entries.4.3.4 Log entries shall be recorded directly by the vesselMaster or may be relayed to another crewmember aboard orcompany employee ashore for permanent recording.4.3.5 Weather conditions shall be recorded by the vesselMaster at the start of the day and prior to each parasail set.4.3.6 Weather logs and the recorded data shall be retainedfor a minimum of 1 year on board the vessel or on the premisesof the place of business.4.3.7 The weather log shall be made available for inspectionby the Authority Having Jurisdiction AHJ when requested.4.4 Weather Limits4.4.1 Parasail operations shall not be conducted when thecurrent observed weather conditions in the area of operationinclude4.4.1.1 Sustained wind speed greater than 20 mph.4.4.1.2 Ground visibility less than 0.5 miles.4.4.1.3 Thunder Storm within 7 miles.4.4.1.4 Wind gust with a differential greater than 15 mph ofthe sustained wind.4.4.1.5 Wind gust exceeding 25 mph.1This practice is under the jurisdiction of ASTM Committee F24 on AmusementRides and Devices and is the direct responsibility of Subcommittee F24.65 onParasailing.Current edition approved March 15, 2019.

United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade TBT Committee.14.4.2 Parasail operations, suspended as a result of weatherconditions exceeding the parameters enumerated in 4.4.1, shallremain suspended for a minimum of 30 min and will notresume until weather conditions are checked and recorded inthe weather log. Parasail operations may resume when aminimum of 30 min has elapsed from the last monitoredweather condition that exceeded the thresholds listed in 4.4.1.4.4.3 Regions affected by prevailing Trade Winds mayoperate provided that4.4.3.1 The sustained wind direction is offshore for theParasail operation, and4.4.3.2 The parasail equipment in use is sufficiently ratedfor the wind conditions.4.4.4 Sea Conditions4.4.4.1 Parasail operations in lakes, intercostal areas, andrivers shall not be conducted when the wave height exceeds 3ft.4.4.4.2 Parasail operations offshore and in open waters shallnot be conducted when wave heights exceed 4 ft unless theperiod and wave height are within the following formula 3 speriod for each 1 ft of wave height for example, 15 s period 5 ft wave height.4.4.4.3 In no case shall parasail operations be conducted inweather conditions that exceed the manufacturer’s specifiedlimitations for the equipment in use.4.4.5 The vessel Master shall be responsible for assessinglocal weather conditions and determining if the weatherconditions are within acceptable limits.5. Equipment5.1 Materials and Manufacture5.1.1 All parasail equipment in use, including but notlimited to parasail canopies, parasail harness, or passengerbars, shall be properly designed for parasail operation.5.1.2 Vessels used for parasail operations shall be specifi-cally built for parasail operation.5.1.3 Parasail equipment shall be operated, stowed, in-spected and maintained in accordance with the manufacturer’srecommendations.
