CCT’s explained – part 3: Determining the Correct Sink Tip Length


Skagit heads combined with modern Spey rods have changed our approach to sink-tip fishing not just for steelhead but also for Atlantic salmon; we now have the ability to fish heavier sink-tips and larger flies than ever before. However, with this change has come some confusion. With the wide range of Skagit heads and sink-tip materials available on the market today it’s difficult to know what’s right for your type of fishing and moreover what’s right for your Spey rod! In this series of articles we hope to throw some light on the subject.

The first article of the series is an introduction to sink-tips, the second is all about is matching Sink-Tip grain weight to your Head weight, this the third explains how to determine the correct Sink-Tip length for your casting style and Rod, the fourth explains how best to cast heavy sink tips and the final article pulls it all together and shows you how to lift your game up to the next level.

Have fun.


Sink-tip Length
While sink-tip weight is extremely important, sink-tip length cannot be overlooked. Back in the early days of Skagit there was there was a formula that said your total length of your Skagit head and sink-tip should be about 3 to 3 ½ times your rod length.  Say what???  Not only did that formula confuse the hell out of the majority of anglers, it also goes against the point of casting Skagit heads.  In an effort to create a formula to standardise the length of Skagit heads, it made things far more complicated than they already were.

Sink-tip length is all about personal preference and casting style.  A taller fly fisherman will cast differently to a shorter angler; the taller guy will naturally have a longer casting stroke, which means he can cope with longer sink-tips e.g 12ft to 15ft.  Whereas the shorter caster will probably prefer shorter sink-tips say in for example 10ft to 12ft range.  Casting style will also effect the length of your sink-tips; a relaxed long stroke style is good for longer tips, and a compact aggressive style is better for shorter tips.  And of course, finally a longer 15ft rod will potentially handle much longer tips than a 12ft rod.

This all sounds pretty complicated but to sum it up in our experience most anglers who fish with a 12ft to 14ft rod seem to get on best of all with a 12ft’ish sink-tip.  A 12ft’ish sink-tip will cover most of the fishing situations found in European salmon rivers.

Fine Tuning
However if you would rather determine your ideal sink-tip length yourself and not just take our word for it then we suggest starting with your heaviest sink-tip cut approximately to the length of your rod. Then go to your local river or lake, tie on a length of leader and the largest fly you intend to use for salmon (or steelhead) and cast a few times. If it doesn’t feel good, then cut back the sink-tip (by say increments of 10cm) and keep repeating until you have found the ideal length for your stroke.  According to Tim Rajeff (and he explained the process to us) it is absolutely critical to start with your heaviest sink-tip.

Once you’ve found your preferred tip length of your heaviest sink-tip, you can cut down your other tips to match the length and grain weight.  Let’s start using some hard values to help explain this a bit better. For example let’s say your heaviest sink-tip for your ECHO 13’0 #7 TR Spey rod is 12ft of T-14, at fourteen grains per foot it weighs approx. 170 grains.   Your slower sinking tips should weigh no more than 170grains and the length should be no longer than that of your heaviest sink-tip.  If we cut 12ft of T7 we end up with a sink-tip which weighs approx. 94grains and you now have two sink-tips with different sink-rates for the same length.

Ultimately, your goal is to end up with a set of sink-tips that match your casting stroke and Skagit head of choice; if you decide 12ft is your preferred length, ideally all of your sink-tips should be around 12ft.  By having a consistent length, your casting stroke won’t have to change every time you change your sink-tip.  It is of course possible to cast using different lengths of sink-tips, however your stroke length will have to change as your sink-tip length changes.  For good Spey casters this is a no brainer but for beginner and intermediate anglers having a consistent casting stroke takes the pain out of casting which results in a massive boost of self-confidence.

    Great articles Stuart. Do you have time for an ignoramus’ question
    Following from “part 3: Determining the Correct Sink Tip Length” I’m interested to know how you would choose the correct length of leader (I wouldn’t want to be cutting back into the CCT if it is the leader which is too long)

    Thanks, Andrew

      Hello Andrew – good question. No rocket science here – if I am fishing in coloured water then I just use about 1m of tippet looped on to the front of CCT, and if I am fishing in cold clear water (like on many of the rivers in Norway) then I would use up to about 1.5m to 2m of tippet.

      Hope I could help – Stuart

    Nice article again. I just love stopping by here. Always something new going on.

    Setting up a comfy sink tip is very important when learning to use and fish with sink tips, but… After you get past the basics then it is the fishing that dictates what tip to use. Choosing the correct sink tip for conditions at hand is many times very crucial if you want to catch fish:)

      Thanks for your feed back Jari, its always appreciated. Perhaps you could give us some examples of the tips you use under which circumsatnces…

    Hi Stuart, would love to do so. These are based on the use of a floating belly. When you use a higher density belly these things change.

    I like to use short tips(6-8′) in low water conditions if I’m fishing so called pocket water. Those short tips have also been very handy for estuary fishing for pacific salmon in low water conditions.

    Standard tips(10-13′) are excellent for getting and keeping your bigger tubes down and are the nicest tip length to use (ImHO). Normal water conditions and plastic tube flies is the scenario that I use these tips the most. Very good tip length also for fishing slower water for pacific salmon/steelhead. I think a 12′ tip fished of a floating skagit gives you a very nice swing and that certain good feel that you need to get a pull.

    Long tips (13-16′) are for deep holes/pockets and fishing slower runs in high water. I personally rarely use anything over 15′. I change the density of the belly if i need more umph in my swing.

    I have noticed that the choice sink tip sometimes makes a big difference in your success. The best thing about using a multi-tip line system like a skagit is that you just carry a set of tip in your pocket and change your tip in mid run if necessary. All and all some spots just fish better with one tip then the other.

      Jari thanks a lot for sharing your experience with us.

    I wish I was better at writing in english. It’s just so slow and hard to get your “message” through when your writing in a foreign language. Maybe I should start learning German? Who knows, I might do a better job at that?

    BTW: one more thing to think about when choosing your tip and the density of your belly is the speed of the surface current. The faster it goes, the longer the tip or the denser your belly needs to be, if you want your fly to go down and stay down.

    These new short skagit heads are in my opinion ideal for fishing pocket water with short tips. You can really get the fly to “hang” in those pockets by mending and lifting the running line out of the water. There’s so little belly in the water to create drag.

      Hej Jari your English is very good (much much better than my Finish 🙂 ) and your the message comes over very clearly. Well done …
      … and thanks for the additional tip.
