How many miles do you cover in a day?

Don't sweat it; just go easy your first few trips. The learning curve is steep, you will learn soo much after the first couple trips...and after a handful of trips, you'll feel like a salty vet. The reason I say take it easy at first is because there are other unexpected things that can't always be taken into consideration (e,g., how your body will react to seasickness).

Taking it easy is exactly what I had in mind.
Haha... especially after reading all these safety reminders.

Now I am getting my ditch bag ready.
