Island Time 1,347 Posted April 30, 2017 Share Posted April 30, 2017 its slightly windier than usual... https://www.instagram.com/p/BTfuFGRDNXe/?taken-by=bigbearandtheloafer Link to post Share on other sites
MasterOfDisaster 0 Posted April 30, 2017 Share Posted April 30, 2017 It's all just numbers past a certain point... Link to post Share on other sites
Island Time 1,347 Posted April 30, 2017 Author Share Posted April 30, 2017 Nope, don't agree. When i was in a 80 knot storm, when it got down to 50 it seemed quite reasonable! WInd force is a logarithmic scale - the force is multiplied way more than the wind speed increments... the numbers mean a lot, and progressivly more not less. Link to post Share on other sites
wheels 544 Posted May 1, 2017 Share Posted May 1, 2017 Yep and temperature has a bigger impact than many realise as well. The colder the air, the more dense it is and we all know about Mass x Velocity.The Ferries did not sail yesterday and the Bluebridge left this morning at 7AM and it took 7hrs to sail across. Yet as per usual, it is Sunny and calm here in Blenheim. Had our first frost of the year. Link to post Share on other sites
Island Time 1,347 Posted May 1, 2017 Author Share Posted May 1, 2017 Absolutely - can hold full sail in the tropics longer than you can down south - but also, wind speed gear accuracy alters with temp/density as well... Link to post Share on other sites
darkside 69 Posted May 1, 2017 Share Posted May 1, 2017 Yes and monohulls record higher wind gusts because the top of the mast is all over the show. Link to post Share on other sites
Island Time 1,347 Posted May 1, 2017 Author Share Posted May 1, 2017 Yep, common DS, but it depends - the really advanced windgear, like the top end B&G stuff, remove mast movement errors (using mast length data and pitch/roll/yaw sensors) and are surprisingly stable and accurate. Even the next level down (Triton) has averaging to try to reduce the error. So the answer to that is, like lots of things, it depends.... Link to post Share on other sites
wheels 544 Posted May 1, 2017 Share Posted May 1, 2017 Temperature also has a big influence on how big waves become as well. For intance, 40kts in the Tropics does not produce anywhere near as big a sea state as 40kts of Cold Southerly down South does. 40kts of Hot norwester on the East Coast will create some white caps and not much wave height, but get 30kts of cold Southerly and there will be a good wave height with it.
