Description of location: Tied up port side to alongside Pier 12 in downtown
Honolulu, Hawaii.

We've MADE IT!!  We are tied up to the dock in downtown Honolulu and I got to command the vessel when docking which was quite fun and INTIMIDATING.  We arrived Monday and had Tuesday off to relax and re-connect with the outside world and family/friends before starting to get ready for our next leg. This is really just a short port stop in a GRAND VOYAGE OF THE PACIFIC (think awesome theme music and credits rolling by).  We sailed over 6000 nautical miles in 41 days.  For some perspective, Los Angeles to Boston is 2, 975 statute miles or 2,585 nautical miles.  If you wanted to do a road trip of the US of around the same amount of miles we traveled, you could drive from Los Angeles, CA to Jacksonville, FL to New York, NY to Eugene, Or back to Los Angeles, CA.  Here are some numbers from the trip.  I think the coolest thing is according to the USGS, the average person uses between 80-100 gallons of water per day.  The other cool thing is that we set the main staysail when we left the dock in Wellington and took it down when we were starting our approach into Honolulu.

This blog post is unfortunately short and has a lot of data (which we all love here).  I didn't realize how tired I'd be when we got in but we've been lucky to work on a slow bell and have a lot of time to just relax.  Check in to the blog again for what we've been doing in our turnaround in Honolulu and the next leg of our voyage to the mainland.  While I'm happy that now I get to sleep through the night and we are not moving, I'm quite excited to get back underway; Bring it on, let's do this, we're ready to blow this popsicle stand (as my mother says).

Editor's Note: In response to the coronavirus pandemic, all SEA Semester students departed our ships on or before March 18, with modifications made to the cruise tracks to ensure swift travel home.  A small, dedicated professional crew aboard the SSV Robert C. Seamans is working in a closed community to return the ship to US waters.  The crew complied with New Zealand's 14 day self-isolation period to establish & maintain crew health prior to departing on their open ocean passage.
