Problems with Midges, Mosquitoes and Sandflies ?

[troppo]

I dream of anchoring in quiet tropical estuaries to enjoy exploring the sandbanks at low tide and do some fishing, but I am wondering how much of a problem the biting insects are on a yacht.

The many hours I have spent on the water in estuaries in my kayak have mostly been blissfully free of the blood suckers, even though once I step on shore, the cloud descends. If on the water I get bitten I simply paddle somewhere else where the bities ain't.

But what about in a yacht? Are the bities less of a problem on the water than on the shore?
