Good advice from jim
not fished Skye but have fished Mull a couple of times
Zulu's and butchers were they way forward.
Fished from the boat drifting the margins casting towards the shore.
Set yourself on drifts along the edges and the fish will come to flies pulled through the waves
bushy and black is almost a panacea although orange can be good in places
Soldier muddlers and the like, loch ordie, blue Zulus and dunkeld won't go amiss
I'd start with black though. Two flies will suffice if you are not into three. I normally only ever fish a max of two flies
and still catch the odd fish or two.
Mull lochs had crystal clear water and large boulders for features
not sure what you will get in Skye.
Hopefully someone has some specific advice
anyway I hope you have a great trip, my plans for July involve flying halfway round the world to fish Haddo
and drink tea with the Nut in the Hut
