my dad keeps telling me that going far in my sailboat would take forever. i only want to go a few miles down the bay. he said it would take 5-6 hours on a light breeze he talking about 8-10mph. i didn't think it would take that long. i know some friends that live down the bay that i would wanna pick up and go sailing is it to far? would i really go that slow that it would take that long? i would be sailing with just a main sail and jib. won't be using the spiniakker till later in the year.

How fast do you generally go?

I keep a log of all my sails so I know what my average cruising speed is. I can make little adjustments if I know the wind will be strong or the current in my favor, etc., but generally speaking I like to use a conservative estimate of 3.5 knots for figuring my expected travel time.

If I know I'll be going upwind, I add an extra 50% to me expected time.

For more complicated routes, I use Google Maps to plot a reasonable course and just take that as the distance.

If you know the tidal currents in your area, you can plan your trip to take advantage of them.

Don't forget to add in prep time. Working alone it takes me at least half an hour to get the boat ready to sail. Can be up to an hour as there are always nagging little jobs to do.

Just about everyone has a handheld GPS to record speed these days. I imagine that your 16' sailboat goes at least 3 knots, which would take 1 hour if you are going just a few miles down the bay. If you need to tack twice it will take about 2.12 hours.

Your speed can be approximated by 1.34 times the square root of the LWL. It is purely The "Theoretical" maximum speed is based on the length of the boat at the water line (LWL). For a 16 foot boat it yields 5.36 knts. It does not account for sail area, keel type, etc. You can also look up the polar diagram for your boat. Remeber this is the maximum speed so you need to use proper judgement.

Or, maybe easier with a:



Sometimes easy is good. Will also give you the distance to get home and you can probably figure out the time it would take.

3-4 knts an hour is a safe bet for your actual straight line speed

Unless you really have to go to work the next day, I won't worry about it. Just enjoy your sail....:D
