The adjustable fin on the ski is designed to “fine-tune” performance characteristics which may vary between individual skiing styles, skier weight and boat speed. There are three types of adjustments that can be made to the fin: depth, length, and distance to the tail.
Distance to the Tail of the Ski
An adjustment forward (toward the tip of the ski) lifts the front and drops the tail during an on-side turn. An adjustment backward drives the front into the water and raises the tail.
More depth improves stability and holding power, while less depth makes it easier to turn.
An increased fin length drives the tip of the ski into the water during the off-side turn. A fin with shorter length raises the tip of the ski.
Each type of adjustment will substantially change the performance of the ski. The less the leading edge of the fin is out of the ski, the more the fin will keep the front of the ski up. The longer the leading edge, the more it drives the front into the water.
In order to accurately verify results, only one type of adjustment should be made between ski rides. Do not exceed .020″ of adjustment per ski ride. Exceeding this tolerance can result in unacceptable results and quick falls.
Once the ultimate fin position has been determined, mark and/or measure the fin position. Therefore, if the fin is accidentally moved the exact position can be easily readjusted.
Wing / Spoiler
The wing is designed to help slow the ski down as you approach the turns. The more angle you set on the wing, the faster your ski will decelerate into the turns. The tolerances for the wing angle should be kept between 6-10 degrees.
ADJUSTMENT OPTIONS – PROBLEMS AND SOLUTIONS
|Difficult to initiate turn||Decrease fin depth, and/or move fin forward|
|Unstable and/or too fast into turns||Increase fin depth and/or move fin backward|
|Too much ski tip in water on both left and right turns||Increase fin depth|
|Too much ski in the water while turning off-side causing breaking at the waist||Decrease fin length|
|Too much ski in the water while turning on-side||Move fin forward|
|Too much ski tip out of the water during on-side turns||Move fin backward|
|Difficult to initiate angle across wakes||Move fin forward|
|Ski overturns and gets too much angle across wakes||Move fin backward and/or add depth|
|Ski changes edges too slowly||Decrease fin depth and/or move fin forward|
|Ski is too responsive||Increase fin depth and/or move fin backward|
1. To adjust fin settings:
2. Record wing angle and remove the wing
3. Loosen Allen screws on the fin clamps to allow the fin to slide with only a slight pressure
4. Adjust to desired settings using set screws
5. Tighten Allen screws to hold fin tightly in place
6. Check measurement after tightening screws as sometimes the fin will move while tightening
7. Replace wing to desired angle using D3 Skis angle gauges
When starting out in the sport, it’s important to ask yourself “What size wakeboard should I be buying?” Well, whether you’re looking to buy a new board or just ride a hire board at your local club or lake, it’s important that you choose the right size board for yourself. Riding a wakeboard too big or too small can make your journey a lot harder, and therefore, a lot less fun.
Different wakeboard manufacturers will have different guidelines for choosing the right size board, but fortunately there is a general guide to follow.
To put it simply – the heavier your body is, the larger the board you’ll need. More body weight requires a larger surface area to keep you on top of the water. OK, enough of the science, here is a table of bodyweights with suggested board sizes:
|YOUR WEIGHT||WAKEBOARD SIZE|
|< 100 lbs||or||< 45 kgs||=||< 130 cm|
|90 – 150 lbs||or||40 – 70 kgs||=||130 – 134 cm|
|130 – 180 lbs||or||60 – 80 kgs||=||135 – 139 cm|
|170 – 250 lbs||or||75 – 115 kgs||=||140 – 144 cm|
|200 – 275+||or||90 – 125+ kgs||=||> 144 cm|
You’ll see there are a few weights that overlap, so if you do ride at a cable park or club, and do get a chance to try out a few different sized boards, then it should help you choose the right one for you.
OTHER FACTORS THAT MAY INFLUENCE YOUR CHOICE OF WAKEBOARD SIZE
Your skill level will also have an impact on the size of wakeboard that’s most suited to you. Some regular riders prefer a board at the shorter end of the scale and others will prefer a longer board.
A shorter board is generally slower on the water as there is less surface area for the board to glide over the surface so can be harder work. On the plus side though, it’s easier to spin and easier to land when you’re riding a smaller wakeboard.
The opposite can be said of the longer boards, they are generally quicker on the water and easier to learn on as they have a greater surface area and won’t sink so easily, BUT, the fact they are larger means they are heavier and therefore harder to perform tricks on. Larger wakeboards can also be harder to land when coming back down to the water after any air or trick on an obstacle.
Taking the above into account, if you are new to the sport, don’t think that you should ultimately buy a longer board to learn on. If you do intend to ride regularly or you have lots of experience of other board sports (snowboarding in particular), then you may find that you outgrow the board too soon and wish you’d gone for something slightly smaller.
If you are a complete beginner then it’s always wise to learn on a hire board to get the feel for it. And possibly more importantly, make sure it’s not a quick fad that you will soon tire of, wakeboards and bindings can be expensive pieces of kit to be left sat in the garage collecting dust.
