Harness Lines Advice

May 9, 2018 by Robin McDougall

Hello. We want to buy Chinook harness lines for Gretchen. Can you reccomend alength and/or style? I got some for myself, but even though I got long ones and keep my boom low, they seem short and sort of hard to get in and out of. I also want to get her an easy uphaul. Thanks! Robin

DUOTONE has very good equipment. I recently bought this one: https://easy-surfshop.com/do/item/DTK-44900-8120/DUOTONE-Chicken-Loop---Quick-Release-FREESTYLE-Kit I recommend to write to them in the chat, they will help. I hope I helped. Bill

Alex and Paul have covered most of the key info, I'll just put my vote in for getting an adjustable set of harness lines at least for the first set. You can make large or small adjustments on the water, so its much easier to get them "dialed in" properly. As you get used to them, you may end up moving your boom higher or lower, and have to readjust them again. I personally use adjustable lines on all my booms because I'll go out in marginal conditions, and if the wind drops I can loosen the lines and still hook in to save my grip strength.

Awesome! I can't find a video but that site has more details on the EZ Uphaul advantages. Here's another picture they have

Lifting the sail without using your hands is an advantage but it goes away in heavy chop/waves where you end up using your hands because of balance. The grips for me work better in heavy conditions.

Don't bother with non adjustable harness lines to begin with. Most forum posts I've read over the years recommend the length to be your forearm from wrist to elbow but that was never true for me. The wave crew here sail with some SHORT harness lines, I hate those. The shorter the lines, the less mistakes you can make and more likely to be catapulted while learning.

OH! I get it now. Okay. I'll check with G and see what she wants. :) Robin

No no, the POWER UPHAUL does NOT hook into the hook. It's just a regular uphaul, with grips.

This is the EZ Uphaul I'm describing:


It has the rope that goes around the boom front, the bungee cord that goes around the mast foot and the loop that you grab and hook into the harness. NO GRIPS.

Sorry, I may have confused you. Unless you're sailing waves, just get the EZ Uphaul.

OH! That makes sense. Basically, they work the same but have different styles of "grip". THANK YOU!

The EZ uphaul works like this (if the image below shows, if not click THIS LINK

With the EZ uphaul, you put the lower hoop around the harness hook and lift with your feet. This takes the strain off your arms and back and uses the harness to lift the sail. This does work but it's not perfect. Notice the EZ uphaul has the KNOTS where your hands go.

The POWER UPHAUL has the EVA FOAM grips. They're just a thick, foam grip that helps you grab the rope. The grip helps tremendously on your hands. I personally found this a bit better for me. You can always add something similar to the EZ uphaul instead of knots. The knots suck. Perhaps the new model of an EZ Uphaul you saw has nice grips now? I'm not sure.

Hi Thanks very much for this information and the link....I am a bit confused. I am looking at images of the power uphaul and the easy uphaul. I don't really see the difference. Can you help me understand what is different about a power uphaul? Thank you! Robin

I have the EZ uphaul and found that I never really used the function where you hook into the harness. I don't think it works that well, specially in choppy conditions. It does make grabbing the uphaul easier by the loop that hooks into the spreader bar but while lifting I still ended up mostly pulling with my hands. Maybe if I had shortened it would have worked better but I'm 6'1.

What I did find worked better for me was the Dakine Power Uphaul. The handles make a huge difference compared to knots on the uphaul itself. Grabbing something that's not a rope feels much better.


For first set definitely get adjustable, I still wouldn't ride without them. Preferences change once you progress and adjustable make all the difference.

ez uphaul is awesome. harness lines can be confusing. several factors: boom ht, position of mast foot, position of lines(fore & aft), wind speed, sail size, venue,etc. fwiw, I use long lines w big sails - 30 cm - they allow me to hook in more easily, hike out on board, and carry the boom higher (mast foot pressure). w sm sails, lines can be a little shorter. many use adj length lines but they are more $$ and must be rinsed freq. fyi, hooking in & out is always a little hop in light air, in heavier air raking the sail back does the trick. great pr photos, btw!
