Beginning in June 2018, the Golden Globe Race will attempt to repeat the famous and infamous race from 1968. 

As their website says:

Stepping back to the Golden Age of solo sailing
30 sailors…30,000 miles non-stop…Alone…With no outside assistance
To celebrate Sir Robin Knox-Johnston’s historic 1968/9 world first solo non-stop circumnavigation in the Sunday Times Golden Globe Yacht Race, a new Golden Globe Race will be staged to mark the 50th Anniversary of that epic, starting from Falmouth on 16 June, 2018.

The race is designed to be intentionally "retro". Further on their website:

As a RETRO Race, for the Golden Globe, generally speaking only equipment that was available to Robin Knox Johnston on Suhaili in 1968 may be used. That means NO GPS, Chart plotters, electronic wind instruments, electric autopilots, electronic log, iPhone, satellite phones, digital cameras, computers, cd players, pocket calculators electronic clocks and watches, water makers, carbon fibre, Kevlar, spectra etc… so it is back to film cameras, cassette tapes, sextants, wind up clocks, trailing logs and Dacron sails, wind vanes and typewriters.

There are some additional details in their frequently asked questions article. What navigation tools would you bring on such a race?
