SAILING NAKED!!!! (Learn to sail without Electronics) chart-plotter

This entry is part 3 of 3 in the series Sailing Naked

So, far we have shed the anemometer and our knot-log. Now for the painful part, the beloved chart plotter. I guess you could say that the chart-plotter is like our underwear (I’ll bet Raymarine, Garmin, Furuno and Simrad never thought their staple product line would never be used in the same sentence with underwear). Both may well be the hardest to shed. But be brave naked sailor want-to-be, we will do it together and get this boat navigation down.

What is it about the chart plotter?

The chart plotter really isn’t all that magical in its basic operation. We attach a GPS antenna, that doesn’t do anything more than receive from satellites our exact position on earth, and places that location graphically onto underlying charts on a TV screen. Yea yeah I know they do lots more buts that’s all extra stuff.

The good news is that if you use your chart plotter then you’re already familiar with using charts. So your dilemma in shedding your chart plotter is just to figure out where you actually are and to locate that spot on a paper chart. That my friends, is known as navigation.

Boat navigation

Boat navigation is the skill set that changes everything. It is what separates people that sail (maybe very well) from sailors. Navigation opens the doors to your dream destinations. Having the ability to navigate safely without electronics allows you to travel near and far with confidence. It also gives you something to do while on that long tack between A and B.

When you set out on your naked voyage you have two choices. You can have faith that Poseidon will guide you safely to where you want to go or you can keep track of your location, study your intended route and monitor your progress making changes and decisions along the way to accomplish a safe passage. The first…yeah, not so much. Navigation takes training and practice. Navigation gives you confidence and once mastered it, is very rewarding.

How to learn boat navigation?

So, how do you learn these valuable skills? The best way is to enroll in an American Sailing Association (ASA) Coastal Navigation (ASA105) class. At Sailing Florida we offer a full range of ASA classes including 105. Yours truly teaches this class and I need the work.

The ASA has established prerequisites for ASA105. Those prerequisites are the successful completion of ASA101, 103 and 104. However, they only apply if you actually want ASA certification. You can attend a 105 class and learn the art/science of navigation without getting certified.

ASA class formats

ASA 105 is offered in two formats. The first is a home-study course where you have the study material and you progress at your pace. When you are done you come to class with me for one day and there we review your work, iron out the rough spots and review for the exam. You then chose to take the exam and have it grade in class or you take the exam home, have it proctored, and mail it back to me.

The second option (and the one that I highly recommend) is a 32-hour class. We can set this class up to fit your schedule (days, weekends, or evenings). Contact Captain Dave or myself to discuss all the options. See you there!

Time to go sailing naked!

So there you have it. We have shed the anemometer, the knot-log, and even our beloved chart plotter, learning boat navigation at it’s core. We’ve talked about alternatives to all these expensive power consuming, mind dulling electronics. We have a path to Sailing Naked, wow I feel free already! FEEL THE BREEZE! YAHOO!

Hey, I just got a great idea. Let’s put together a Naked Sailing trip. Let’s set out on a journey! Let’s go to Key West NAKED! I like it! Contact Sailing Florida or myself and let us know your thoughts. We will learn a lot, have a lot of fun and accomplish something that not many have tried. Basic sailing skills will be required (and maybe no cameras) but that’s about it.   I love it when a plan comes together.

Thanks for reading and I expect to see a bunch of naked sailors on the dock. You know I’ll be there. Go out sailing and be On the Water…With Captain Frank…Naked!

SAILING NAKED!!!! I have the guts, do you?

This entry is part 1 of 3 in the series Sailing Naked

Part 1 of 3 (I think)

Sailing Naked

For those of you that have actually met me you might be thinking; “Oh no Captain Frank please, you’re gonna make me go to therapy to get that image out of my mind. How could you”? So, before you dial the out-reach hotline let me assure you that I will remain fully clothed when I sail, most of the time anyhow.

What I’m talking about here is going sailing and leaving the electronics turned off. Actually turn them on but cover them all up except for the depth instrument. Whether you’re day sailing or taking a trip to destinations near or far, sailing naked will dramatically improve your technique, confidence and navigational skill. But it takes practice.

In this series we’ll take a look at our electronics and how we can get over our addiction to them. Let’s start with the anemometer.

Our anemometer:

The anemometer utilizes a weather vane to gather wind direction data and a series of cups or paddles that spin in a circle to relay to us the wind speed. We don’t need that digital windmill on top of the mast. We have everything we need to know where the wind is right next to (not under) our nose. If you turn your face very slowly you will know exactly when the pressure on both your cheeks is the same. If your hearing is good enough you will hear the wind in your ears. At that moment you are staring exactly into the wind. With practice you will learn to stand behind the helm with your face positioned so you know where the wind all the time. Anemometers are notoriously inaccurate and often incorrectly calibrated. Most of the time they are giving you bad info anyhow. Regarding wind speed, get familiar with the Beaufort scale so you can identify the wind speed by looking at the sea-state (the waves).

Close hauled:

If you are sailing close-hauled then depending on your boat and the tack you’re on you should be looking some where between 1 and 2 or 10 and 11 o’clock. Trim your sails in close. If you are heeled more than about 12 degrees, or if you have more than 4 degrees of rudder applied or if you can’t hold the helm with two loose fingers then you have either poor sail trim or to much sail up. Fix it! Less sail area trimmed well is way faster than too much. Keep those tell-tales flying and the main from luffing (unless you’re double reefed and still have to much power (what the hell are you doing out there anyway?)).

Close reach:

The wind is on your face from 1:30-3 or 9-10:30 o’clock. Trim the jib to make the tell-tales fly and trim main until it just starts to luff, then ease it slightly. It’s that simple. Close reaching is what God actually intended man to do. It’s just right.

Beam reach:

We all know what a beam reach is, right? The wind is blowing perpendicular to the centerline of the boat (right across the beam). If you turn your face to the 3 or 9 o’clock and your face is getting that “I’m in the wind” feeling then guess what. You’re on a beam reach. So, trim your sails silly.

Broad reach:

Okay, I’ll admit, it’s harder to tell where the wind is when it’s behind you. However, last time I checked my spine and neck were capable of rotating and while the wind pressure on your face is less apparent (because the apparent wind is less), it is still present. All sailboats with a jib have a built in alarm system forewarning of the dreaded accidental gybe. As we sail deeper off the wind we ease the main further and further out.

Eventually the main steals the wind from the jib (sneaky greedy man, shame on you) and the jib gets weak and finally collapses from lack of oxygen. This indicates that you are getting into the gybe zone. Turn the boat slightly upwind and jib flies proud again. So see, we don’t have to have a TV screen telling us what’s going on, our sails tell us. By the way here’s a great little tip. If you see that collapsed jib turn the wheel away from the boom to prevent the gybe. Wheel toward the boom to gybe, wheel away from the boom if you’re scared.

When we broad reach we are pretending to be a “square rigger”. It’s all about presenting sail area to the wind. Don’t let your jib billow out in front of the head-stay. We want to create a wall perpendicular to the boat centerline with the luff of the jib. If we let the jib billow in front then we have given away the largest area of the sail. The luff area is parallel to the wind (not very fast) rather than capturing the air (fast).


The jib tells you when you’re running. It’s trying to get to the other side of the boat. Let it go! If it loves you and you let it go it will stay with you.

Well there you have it. The anemometer is no longer holding you back from sailing naked.  We’re one step closer to sailing naked!

Till tomorrow when we get together again On the Water…With Captain Frank
