Rockpool Taran Bow / Stern Guards

by John Willacy


Here we take a look at the fitting of Bow and Stern guards to the Rockpool Taran. But before we get in to the how-to maybe we should take a look at the why (or why not).

First take some time to consider the nature of the Taran and your paddling style. The Taran is a low-rocker sea kayak. It is designed as a performance sea kayak and as such requires a little consideration from the paddler. The Taran will not change to match your paddling-style; your style needs to adapt to match the Taran! The low-rocker hull means that any mistreatment results in wear and tear being concentrated over very small areas of the hull.

Avoid seal-launches, dragging the boat or landing bow first on steep landings. The boat is not designed with these in mind. Try whenever you can to launch and land the boat afloat, and think about the positioning of the ends of the boat. Treat them gently.

Treat your boat with care.

People like to individualise their boats, and fitting end-guards can be useful at times, but personally I feel that avoidance is better than cure.

I have a bow guard fitted to the Taran I use for running the Bores, the shallower ones can result in the bow sliding along the river bed. I also have one on my first UK circ boat, it was useful for solo scratchy landings. However I didn’t have one fitted to the 2nd UK Circ boat and it survived pretty well. But I did take care of it. My daily paddling boats don’t have guards at all.

Stern Guards I feel are less important. Fit one if:
a) You are going on a long-solo exped where you will likely drag the boat.
b) You are very hard on your boat.
c) You are really just rather careless. (Excluding point a) – should a 3 grand boat be dragged on the whole?)

The idea

When the Taran was being built for my first UK circumnav we took an idea from my days of Wild Water Racing and fitted it to the Taran – the composite Bow Guard. As a WWR paddler on the shallow, rocky rivers of the UK you learn that the Bow (or Rock) Guard is indispensable to keep a boat hull in race condition.

It’s a simple idea: lay-up a few layers of Kevlar braid (or tape) on the bow of the boat. Once this has cured it provides a tough shield against wear and moderate impact. Weight is minimal (a matter of grams) and if constructed carefully it provides minimal drag to the boat too.

A well worn, chunky bow-guard.

In the racing world the Bow Guard is designed to be removable, held in place with tape for training and easily removed for racing. With the Taran a removable guard is less significant. The added weight or drag is minimal.

A slighter version of the bow-guard.

This guide covers the building of a removable guard.

Building a Bow Guard

First choose your fabric. Kevlar braid will give a very tough guard but can become quite bulky. Kevlar tape results in a more minimalist guard but gives less protection. I use tape for my faster boats and a combination of braid over tape for my heavy wear boats. A reasonable compromise would be 2 layers of 25mm tape overlapped by a layer of 32mm braid. You can use wider fabrics but that may make the guard quite bulky and may be overkill.
A little Peel-Ply can be useful to tidy things up too. You can use either polyester or epoxy resin, though using epoxy will give a much more robust guard.

Cut your material to length – start at the lower edge of the seam and ‘stretch’ the tape around to the keel a little beyond the end of the curve.
You are going to lay-up the fabric on the hull so you need to ensure you can release the finished guard and keep the hull clean from excess resin. So you either can use release agent/wax or for a rough and ready but effective method you can use food wrap (Cling Film). If figure if you are using the former you probably don’t need help from this guide, so we’ll take a look at the Cling Film method instead.

Turn the boat upside down and stretch a layer of Clingfilm over the bow area. Hold the edges in place with masking tape – tension the Cling Film to make it as smooth as possible. Ensure you cover well beyond the working area or you will spend time scraping off resin drips later!
Cut strips of your Kevlar Tape to the desired length, the more strips the stronger the guard but thicker the finished piece. You’ll get a better finish if you can lay up the widest tape on the outer-layer.

Paint a layer of epoxy resin over the Clingfilm in the area where the guard will be. Wet a strip of Kevlar tape on a piece of cardboard and then place it onto the Clingfilm. Wearing gloves(!) – gently ‘pinch’ the tape and run your fingers along the tape from the centre out towards the ends. Repeat this until the weave in the Kevlar tape stretches (a little) and the Kevlar tape holds in place without any puckering along the edges. This may take a little time – be patient! Add your next layer of Kevlar tape and repeat, until you have the required number of layers. Ensure each piece of Kevlar tape is slightly longer than the previous to give a smooth overlap at the ends.

This next stage is optional, it gives a smoother finish but takes a little practice (and patience).
Finally place the Peel-Ply over the last layer of Kevlar tape with a good overlap. Now using your fingers once again smooth the Peel-Ply as per the Kevlar tape. The Peel-Ply does not stretch like the weave in the Kevlar so this can be rather fiddly. With patience (and a dollop of resin) it should give a smooth finish with no puckering. However it can be tricky – remember this one is optional!

Allow it all to go off (overnight – needs to be warm) and then remove the whole thing from the boat. Don’t remove the guard until it has gone off fully or it will distort. Discard the cling film and masking tape, remove the Peel-Ply and then trim any sharp edges of the Bow Guard. Use a hacksaw/band saw to trim the end to length as necessary.

If it is to be a removable guard then drill a small hole at the top, to thread a thin lanyard which in turn is tied to the bow-toggle. The guard is now attached to the boat with a couple of strips of gaffer-tape running across the top end of the guard. Don’t put anything at the bottom end; it will peel away producing a small fountain of drag! Don’t slide the boat rearwards with a taped guard, it will catch and peel off.

Alternatively the guard can be held permanently in place with a thin layer of waterproof grab-adhesive such as Sikaflex.
If you hit anything now the guard will spread the load and minimise damage to the gelcoat.

Stern Guard

On the stern a similar process can be used.
Here a removable guard is less useful. The rear guard is designed for wear rather than impact and so the guard really needs to be a permanent addition for sea kayaking – effectively building a mini-keel strip over the stern of the boat.

I make my stern-guards around 75cm long, reaching from the very end of stern keel. Use wide Diolen or Kevlar tape (50mm). Mask an area of boat to give a slight overlap beyond the fabric tape. Roughen this area using a ‘nylon sanding wheel’ on an electric drill. Clean and remove all dust. Wet this area with resin and then wet the tape separately. Lay the tape on the boat, remove the masking tape and allow it all to dry to the touch – it doesn’t have to fully cure. Re-mask and now paint on a layer of gelcoat or thickened resin (if using epoxy) to give a smooth finish. Mask the leading edge to a point.
Remove the masking tape once again and now you have your stern guard.

 

Here is a summary list for fitting a Keel Strip, the same method is used to make the shorter Stern Guard.
