Roger, You did something great by stirring up people to get on the air. It was partly the participation that's created the "good conditions". 160 m almost always has some propagation. I often call CQ

Dave, For those of us who like CW, it will always be the preferred mode. FT8 may lower the DXCC threshold; perhaps it should be counted differently. But FT8 is opening 160 m to hams with limited faci

The vertical near the sea will benefit from in-phase reflection (which is additive) of the vertically polarized radiation. That is probably worth 3 to 6 dB, depending on the angle, etc. Ground losses
