Then to the South Continent 63 ..since black clicking reveals also the visible mass to the SW was 63....
That's odd - "63" is usually reserved for lakes. Maybe the designer has taken some measures against black-clicking ? Also, it's a clue that the game is a scenario, with no "2/3's rule" on tech choices (which you can verify from the civ score menu).
I am still undecided about whether to aim for Lighthouse or for Seafaring first. With seafaring, and ship-chaining, you can send units across the sea (up to about 6 tiles wide) without risking the units. Only one boat might be lost, which seems an acceptable risk. But I am concerned about the beaker cost, of researching pottery+seafaring so early... well, such decisions make Civ2 fun!

As for what to produce first, why not a settler, as usual? You can even try the size-one trick. Of course, you'll need a boat pretty soon, or your settlers are deadwood.
