Anthony Smith, 85, wanted to complete the 2,800-mile (4,596km) voyage to highlight the fact a billion people worldwide live without clean water.
The former BBC Tomorrow's World presenter hopes to have raised £50,000 for the charity WaterAid.
They set sail from the Canary Islands and reached the Caribbean on Wednesday.
