If you want something more colorful, and don't mind the annual subscription fee, you can use SailBlogs | Sailing Blog Hosting & Social Network
. There is a built-in template for sailblogs in the Airmail/Sailmail software
that makes it easy to post blogs and positions (on their map). You can even attach a small picture on the email
that will show up with your commentary.
Position reports to Sailblogs only show up on their map/site. If you want your vessel to show up on Yotreps/Shiptrak.org you would also use the "Position Report" template in Airmail.
