Hi Amph ,
AHHH , sailies ...
Your gear seems fine , I would reccommend a longer line though , I normally use 40 m.
What depth is the water ? I have found most of my sailies around 30m. , cruising in midwater moving upcurrent .
They tend to be very inquisitive and will readily approach flashers . You can often dive straight towards them and they will turn nicely sideways to eyeball you . Don't startle them by hurrying too much ; nice and easy does it ...
As always let the fish pass you slightly below you and place your spear slightly from above and behind , entering behind the pectoral and exiting the opposing gillplate . You can also go for a brain or spine shot , the skin and flesh is very tough and you should have little worries about tearouts .
Though not very fast these fish are strong so let it swim , applying moderate pressure on the line . I usually just hang on at the float for the first 20 mins. or so and then gradually start working my way towards the fish .
Like marlin , when they tire it might try sounding . If there are deep pinnacles or stuff it might get hung up on you need to make sure it can't get too deep .
Be careful of touching your sailie with exposed skin , they cause a rash similar to whale sharks ect .
BTW for sailies I usually hang my flashers at 1/3 depth of water .
