I have a dear friend, who I call "Popeye" and his father, whom I warmly refer to as my own "Dad", on a lovely sailboat called KISMET from San Fransisco, Ca.
They both have been sailing around the world for about 5-6 years and are currently in Langkawi, Malaysia
at The Royal Langkawi Yacht Club.
I haven't heard from either of them for 4 days. We usually communicate on a daily basis, and if they do need to take a visa run or a visit to the doctor's office, I'm usually informed before they go.
Last we chatted, Dad told me him and Popeye were going to go play cards, and that was on January, 8th.
What would be the normal procedure to make contact in order to see if everything is alright? I am starting to have concerns.
