Click Here to view the ships details and then under the "Last Position Received" section of the page look for a link titled "Current Vessel's Track"... (It appears to now be showing as 'Not Currently in Range', perhaps their communications are cut off)
Once you click that, you should see a picture which can be zoomed in and out, like the one below...
You can use this site to track any of the future flotillas heading towards Gaza if you are interested...
