Feature
This week’s offering will be a bit
light as I’m trying to get something assembled before going
on vacation to Ireland. While there, we will be travelling
near the home of St.
Brendan, a 6th century Irish monk, who
is reported to have crossed the Atlantic to North America a thousand years before Columbus.
Similar to Thor Heyerdahl
and his Kon-Tiki and Ra Expeditions, Tim Severin’s
team built a wood and ox
hide coracle and succeeded in duplicating St. Brendan’s
crossing by sailing
from Ireland to Newfoundland. His book, The
Brendan Voyage, is an account of his experiences.
Try your hand at a DIY coracle.

Units.
