The Lt. Columbo Forum
An area where fans from all over can ask each other questions and voice their own ideas and opinions on anything Columbo.This Forum is fondly dedicated in memory of "cassavetes45" (Carleen Zink),
Columbo's greatest fan and a great friend to us all.
Don't ever stop being silly Great Santini...it wouldn't fit you.
And I loved the clever way you inserted the 45 in...it definitely worked for me!!
It's funny that you mention the Thames...because I was talking to my sister today and she pronouced it like rhyming with "James" and I had to correct her...but I did it nicely.
Other boat/ship/yacht trips that Columbo took were in Dead Weight..his frightful journey with General Hollister....and The Last Salute to the Commodore..where he rides off in the rowboat.
To be fair, the first time I saw Thames written down, I assumed it was pronounced with the "aims" sound, like "James" is, so it's an easy mistake to make, and on that is much easier if nobody has ever corrected you. Who knows how many words there are which I could encounter and not be sure of the correct pronunciation? No doubt a great many.
As for Columbo's watery expeditions, let us not forget that he dabbled in the shallow end of the pool in "The Most Crucial Game", getting his foot wet enough that he had to walk around without one of his shoes. If not a boat/ship/yacht trip, can we at least call that a paddle, albeit an unintentional one? 
It's a stretch....but since I am in a good mood, I'll buy it!! Nut!!!
