Buying a Kayak 101

You're in the market for a new or used sea kayak. Now what? Unless you're an entirely impulsive person, buying your first kayak can be an overwhelming process.

I'm a strong believer that, if you're new to the sport, the best tactic is to educate yourself. One place to start is a retail shop that allows on-water demos. Test-driving a kayak is as important as test-driving a car! Taking a class from a reputable instructional school is another way to learn more about sea kayak designs, and will help you determine what features and designs are right for you.

A few common questions that new buyers agonize over:

- Should I buy plastic or fiberglass?
- What features should I look for?
- How do I know if a kayak is well made?
- What should I look out for if I'm buying a used boat?



PLASTIC OR FIBERGLASS?

Sea kayaks are made in a variety of materials: wood, canvas, plastic, fiberglass, kevlar, carbon-kevlar. Since plastic and fiberglass are the most common materials, I'll limit the discussion to those two.

Each has it's benefits and drawbacks. Plastic is relatively inexpensive, recyclable, and has tremendous impact resistance. On the other hand, its less stiff, deforms and weakens with exposure to heat and UV, is heavier, and is difficult to repair. Even all plastics are not made the same. Single-layer polyethylene boats tend to be less stiff. Several companies, including P&H and Valley Sea Kayaks make 3-layer polyethylene boats, which sandwich a foam core between two layers of plastic, resulting in a stiffer, lighter, and repairable boat. Most recently, thermoformed plastics are now being used for kayaks. These can be molded into more precise shapes, and are very lightweight but lack the impact resistance of polyethylene.

Many new paddlers shy away from fiberglass boats because they believe they're less durable than plastic. Spend a week with paddlers on the rocky coasts of Rhode Island or Maine and you'll see how false that is! Fiberglass boats can take a beating...but most importantly, they can be repaired easily and effectively with materials that are readily available to every boater. Composites are lighter, stiffer, and can be molded into finer entry lines than their plastic counterparts, which makes for a faster, more responsive kayak on the water.

8 FEATURES TO LOOK FOR

For a sea kayak, the following features are a must:

1) Good Bulkheads. At least two bulkheads (foam or fiberglass walls that divide the boat into compartments...this keeps the boat afloat after capsize and aids in draining the boat of water during rescues.) Bulkheads can be made of foam, welded plastic, or fiberglass.

2) Does it have a day hatch? The day hatch is a small third hatch accessible just behind the seat. As the name suggests, it's a place to store items that you might need quick access to, e.g., flares, first aid, GORP, or a camera. This is a feature that I have decided I can't live without!

3) Recessed deck fittings (RDFs). Deck fittings secure the deck lines and perimeter lines in place. These should be recessed into the deck, rather than protruding out from it.

4) No screw holes! One mark of a well made boat is that all the fittings are connected to molded brass inserts...there are no bolts coming through the kayak. Bolts can snag and tear dry bags. But they also can come loose, allowing water to enter your boat.

5) Skeg, Rudder, or None? This is the classic "less filling v. tastes great" debate of sea kayaking. Without getting into the relative merits of skegs and rudders, let me tell you that anyone who says that a rudder is necessary to turning doesn't know a thing about paddling! The truth is, both a rudder and a skeg are used for the same thing: to "trim" the kayak when paddling in a beam wind. This keeps the kayak on course. Turning is effected through proper paddle strokes and boat edging. Remember, 90% of the time, your skeg or rudder will not be deployed. With that in mind, it's up to you to determine whether during that 90% you'd prefer to have your stern end adorned with a sharp metal mechanical device rigged with steel cables or a nice skeg which won't slice and dice you like a tomato during rescues and surf landings! Any guess which side I'm on? ;)

6) Good hatch covers. This is what keeps the water out of your boat. If a hatch cover comes off too easily, that's not always a good thing. You don't want it popping off if a wave breaks on it, or if your scrambling up the side of your boat during a reentry. Kajaksport and Valley hatches are the best. See if pressure on the center causes the edges to pop off, or if you can accidentally pull the hatch off...if so, you may want to look at another boat. You can also check the seal buy putting water IN the hatch and tipping the boat upside down...if it leaks out, you've got a poorly fitting hatch.

7) Toggles. This seems simple enough, but this is one area where well-made boats stand out. Bow and stern toggles should run through the end of the bow and stern, rather than being bolted in with a fitting. A toggle running through solid plastic, or in the case of a fiberglass boat, solid resin block in the ends is less likely to fail. Toggles are used for hanging on to the boat during rescues, but they also end up being used for carrying the boat, tying off bow and stern lines, etc. You want a strong connection there.

8) Outfitting. You should feel like you're wearing your kayak, not sitting in it. To that end, thigh braces are a must. However, remember that outfitting (seat, thigh pads, etc.) can usually be adjusted to fit you or retrofitted with closed cell foam. Bolt-in (rather than molded in) seats can be removed to provide a lower center of gravity; back bands can be swapped out; hip pads added in. In other words, buy a kayak based on its hull, not how cushy the seat is. This is the least important part of your decision making!


USED BOATS: BUYER BEWARE

Buying a used boat can be a great cost saver. A kayak is a pretty simple machine...there's not a lot that can go wrong with it. However, there are some things to keep an eye out for.

Plastic boats
1) Look for deep gouges and excessive wear on the hull.
2) Examine all the bulkheads. If it's a foam bulkhead, it can easily be resealed with marine-grade silicon caulk.
3) Check for "oil-canning." These are permanent bulges on the hull of the kayak, usually from years spent cranked down on a rack.

Fiberglass or composite boats
1) Shine a flash light through the hull to look for thin spots or evidence of repairs.
2) Check the seam (where the deck and hull are connected by a piece of 2" fiberglass tape) to make sure it's intact.
3) Check the gel coat for chips, gouges, and cracks. Spider(star-shaped cracks) and hairline cracks are common in the gelcoat of fiberglass boats. This occurs when the boat flexes under stress (from loading, surf, or the weight of a paddler doing a jig on the back deck) and the gelcoat, which is less flexible than the fiberglass under it, gives. This is common over the bulkheads. However, a spider crack in the middle of the freeboard may suggest a collision, so be sure to inspect the glass behind it.
4) Check to make sure the bulkhead glass is intact.


All boats
1) Check the hatch covers. Rubber hatches should be pliable and fit tightly on the rims. If they appear cracked or are very loose, they are UV damaged and need to be replaced. If so, be sure the hatches are still available for that model. Most British boats use standard covers from Valley or Kajaksport, so that's easy. Many American manufacturers make their own hatches, so that could be tricky.
2) Check all lines for fraying. Deck elastics should snap tightly against the boat. Lines and elastics can easily be replaced.
3) If the boat is equipped with a skeg, make sure it deploys fully. If it has a wire skeg, examine the skeg cable both at the slider and at the skeg for evidence of past kinking. If it has kinked once, it's bound to do it again in the same location.

Spring Cleaning

I hope all of you have been out paddling by now. I also hope all of you have also taken time to critically look at your paddling gear to make sure it is ready for another year of paddling. If not let's go through the most important pieces starting with your PFD.






Make sure it has no tears or parts that have become unstiched. Check to make sure all the zippers, snaps, and adjusting buckles still operate. Check the fabric, adjusting straps and buckles to ensure they still have there orignal strength. Remember your PFD is exposed to the same UV radation that we are but does have the benefit of sunscreen so over time it degrades loosing its structural integrity. Usually this can be seen as the color of the vest isn't as bright, but be sure to pull and tug on the fabric to ensure its strength is still there. Having your vest coming apart in the water would not be the best way to test your vest.





Next your let's take time to examine your spray skirt. Begin on the top surface looking for worn spots, holes, and tears. Also look at the tunnel area (the part that goes around your chest area) for damage. Remember that dirt acts as a grinding agent that slowly destroys your skirt, so a clean skirt will last longer. Flip the skirt over and look at the underside for worn areas, holes, and tears. Be especially mindful of the area that attaches to coaming of your kayak as this area experiences the most stress and wear. Finally check to see that it has the correct tension when pulled over your cockpit. To loose and it won't be able to stay on in choppy and rougher water. To tight and you may struggle trying to get it on and off.





Take time to look at your paddles, both primary and spare. Begin at a blade on one end looking for cracks, chips, anything unusual. Work your way down the blade to were it joins the shaft. Make sure it is still firmly attached, again checking for cracks, splits anything that looks unusual probably needs closer examination. Continue up the shaft looking for the same thing, and continue until you reach the end of the other blade.


Finally take the time to give your kayak a good wash both inside and out. This is the time to check for cracks, dents, God forbid holes. Afterwards start at the bow or stern and slowly work your way to the other end. Check the toggles for wear, ensure the hatchs still seat properly. Look inside each hatch compartment to ensure the bulkheads are still in place and firmily mounted. Check all the deck lines and bungees for wear and replace anything that is worn. Take plenty of time in the cockpit. Check the back band, seat, footbraces, and thigh braces for wear, broken parts. Again TAKE YOUR TIME, this is where you work and play, make sure its functioning properly. This is also a good time to add any padding to make it more comfortable or make it fit better.

Most of this can be done down the basement or in your garage on one of the many rainy days that have been occurring. One of my favorite passages "The sea favors the prepared" comes into mind when I'm examining my gear. Well today is suppose to be sunny and cool but I can't think of a better day to be on the water. Hope to see you there.

Whitewater Fun on the Yougiogheny

On a late weekend in April the 41 North crew, Marc, Marius, Nic, Josh, John, & Wendy along with Sarah, Damon, & Scott from Riverside Kayak and of course Kelly Blades (BCU regional training coordinator)met to whitewater the Yough.
This is the Ohiopyle falls just above where we put in to go down river.





Here's all of the crew gathered together for some final suggestions before we go down river and a motivational speech for those who are anxious at their first attempt at class III/IV river.

Marius playing and showing some of his moves.








Mark and Marius waiting in line to play in the waves.








Mark and Marius on the same wave, making it look easy.









Smiles from Josh (j man) after riding some waves.







I know we all had a good time paddling that weekend. For most of us it was a new paddling venue that allowed us to practice existing skills in a new environment. Some of us swam and some didn't. Josh experienced being pinned to rock by the current, and I glad to say he was no worse for the experience. The area was beautiful and being in the gorge was amazing. Hope you are all out paddling and we are looking forward to seeing you this summer.
