Out of intrest... would you say black sand is larger grain (heavier?) than 'normal' (golden) sand?
I wondered as it looks like the 'black' dunes have a bit less 'slope' than some of the dunes we soar in Scotland, so would need a bit more wind for good lift.
hmmm... interesting... i actually think its very fine grained sand, but wouldnt necessarily know the difference... I guess the wind was about 6-8ms while it was working best... but right behind the dunes we have powerlines... so best to avoid too much wind ;-)
Looking at 33 sec in the dark 'steps' in the sand tend to indicate to me that the structure of the dunes may have a higher 'grain to grain' bonding than the golden sand we tend to have in the UK, where dunes tend to have a 'soft' outer layer except for a couple of days following the outer layer being scoured by gale force winds.
Our dunes appear to 'curve' to a far steeper top section than these black sand dunes, so need less wind to soar.
The 'knife edge' dune Lunan Bay can be soared with 6kts (3 m/s) but is more often soared in 10-15kts but in as much as 70* 'Cross' wind... giving slow into wind beats and as much as 35kts (ground speed) F A S T ... down wind beats... :-)
I often fly dunes/small ridges in 20 PLUS kt winds due to the wind VECTOR... being angled upwards... this results in the horizontal component of the wind being well BELOW 20kts... in the ridge 'sweet spot' :-)
great! love it...

right... so, how much wind do you usually need for your dunes?

það var svona 6-8 á meðan þetta var að virka sem best... þetta er ströndin á milli Þorlákshafnar og Eyrarbakka... heitir Hafnarskeið.
