Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[Q]: Assuming two different trips - one with a current and one without, what is a reasonable speed to assume for a journey?

First - Norfolk, VA to Bermuda to the Azores to Liverpool

Second - Liverpool to the Azores to Bermuda to Norfolk, VA.  (funny how I did that, no?)

I'm trying to get an understanding of how fast a regular sailboat, not using power, traverses a wide body of ocean, both with and against a current.  A rough order of magnitude for a lesiurely rate of speed is what I'm after here.

As far as size goes, consider a private craft, again, under sail, not engine, maybe 30' - 40'. The idea would be a boat two people could crew and afford :). Feel free to make other assumptions- the idea is to understand if I'm talking days, weeks, or months. 

[A]: How fast can one expect to travel in an ocean-going sailboat?


[Q]: I see on Wikipedia that both Vietnam and Philippines honor an IDP. However I cannot find specific information on whether my motorcycle license would translate and allow me to rent and drive motorcycles in the two countries. Will an IDP allow me to do so?

[A]: Will my US motorcycle license translate via International Driving Permit in Vietnam and Philippines?


[Q]: I'm planning to go to Germany next year. A direct flight from my home country (Dominican Republic) would be about USD $1400. I have B1/B2 US visa and I was wondering if it'd be possible for me to purchase a round-trip flight from DR to Miami and then a second round-trip flight from Miami to Frankfurt. That'd save me up to $500 dollars, which is a considerable amount. I'd like to know if there'd be any issues with me entering the U.S twice in such a short period of time (around 10 days).
