Digi cams don't do OCR well so I scanprefer.

Looks like the control room of the Thresher. Which one is the laser ring gyro?

You can hook cheapo gps with maps to nmea radio offshore correction by coastguard channel for about 1 G. I wouldn't thread a narrow approach with that though. It does not do the really accurate differential mode. Satellite corrected feed sounds like the ticket but it would be a few shekels.

I do seat of the pants correction by squinting at the sun and saying the LP while tasting the seawater. Radar and Loran C is as high tech as I go.

Slocum circumdeviated the orb with a chronometer without a minute hand and was rarely a mile out using C. Cooks charts of NZ and such. Actually they were Bligh's charts. Bligh was the navigator, Cook took the credit.

A 25 ton ferrocement Sharpie gaff rigged Ketch, ratlines and belaying pins, all hand winches, with 3 foot draught and 1200 sq feet of sail. Does 15 knots under sail in a 20 Knot wind. Standing headroon to forecastle and 13 foot beam. Nominally 40 nautical feet long.
