100 Scuba Diving Facts for the 100th Blog Post

The Scuba Blog had it’s first post in September 2013 about our trip to Mermet Springs in September 2013. We’ve come a long way since that first post. We’ve celebrated 2 Halloweens, 2 Thanksgivings, 2 Christmases, 2 New Years, multiple diving trips to Cozumel, Beaver Lake, Mermet Springs and other many other places. There has been good weather, bad weather, sunny weather, cold weather. We’ve had scuba educational posts, try it posts, and even posts about the enforcers. There have been posts introducing all the employees of Extreme Sports Scuba, all the kids who dive with Extreme Sports Scuba and now we’re on to learning about our adult divers. As you can tell a lot of things have happened since September 2013 and that first blog post that went live, but I’d like to mention another mile stone we’ve hit is the Blog has hit its 100th post. Can you believe there are 99 other posts on the blog about lots of events and educational opportunities that have been experienced through Extreme Sports Scuba.

For our 100th post we thought it might be fun to expose you to 100 facts about Scuba Diving. I know 100 facts sounds like a lot, but remember, we’ve hit a mile stone and there are a lot of good facts, trust me, I’ve been doing my research. Now I’m not going to take all the credit here, nope, I’ve had help from Deb Weston, Justin Weston, Doug Lord, Rachele Lord, Scott Dawson, Joshua Gilmore and Aerielle Cupp. I hope you enjoy reading this 100th post as much as I have enjoyed piecing it together. And just think… some day when you’re on a trivia show and that 1 Million Dollar Question comes up and it’s about Scuba Diving, you’ll have the answer and you can thank us :). Enjoy!

Kayak Facts

90. 1- There are two types of Kayak’s, sit-inside and sit-on-top of kayaks.

91. 2- Sit-inside kayaks place your center of gravity inside the sidewalls of the kayak and your legs are under the deck. This keeps splashing to a minimum as well as keeping your legs fairly warm and dry.

92. 3- Sit-on-tops are more for warmer weather paddlers as you will get wet, but they are great to hop off of for a cool down swim, then jump right back on and continue to your destination.

93. 4- Long skinny kayaks are great for speed and tracking where shorter wider kayaks are very stable and maneuverable but not as good with tracking and will be a bit slower.

94. 5- Flat bottom kayaks are very stable but slower where as v-shaped kayaks will be faster than a flat bottom.

95. 6- Most generally a sit on top of kayak is more stable than a sit inside kayak and will run in shallower water, which is better for rivers and streams.

96. 7- Advantage to buying a kayak from a local dealer, the local dealer can handle the warranty in house where as a larger warehouse store requires shipping the kayak back to them which could get a shipping cost upwards of $150-200.

97. 8- A common misconception with kayaking is you don’t have to roll a kayak over (that has to do with white water kayaking). In recreational kayaking if the kayak rolls over you get out/off, flip it over, get back on and continue kayaking.

98. 9- Fishing off a Kayak allows you to get to most places a boat won’t let you.

99. 10- Watching and reading about Kayaking on the internet is not always the most reliable source unless you know where the facts are coming from. Northwest River Supply started in 1972 has a great learning page with facts and videos to help with any questions that you might have (or going in to your local dealer!!).

And last but not least, the 100th fact…

100. If there’s food, they will come.
