Re: Sleeping While at Sea
With two onboard we are able to keep reasonable watches. The person on watch stays awake (generally!) and checks for vessels every 10-15 minutes (to me 20 minutes is too long with the speed of some freighters, especially with visibility that is less than ideal). You can't judge the risk, ie number of boats, by distance offshore. Some very busy shipping lines are very far from shore, eg. between South Africa and Asia south of Madagascar, the number of ships going to Richards Bay and Durban is huge, plus all the ships going around the Cape.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
