    hey guys,

    im not yet certified but i hope to be soon. ive enjoyed reading all of your posts and i have a few questions.

    im a big guy (6'1" and 350lbs) can anyone tell me how this will affect my diving.

    ive contacted local dive shops and they say the weight thing is not a problem.

    i know that i have to be able to tread water for 10 min. and have to swim 200 yards. i dont have a problem with either of those.

    do i have to wear a wetsuit in warm water?

    is it going to effect my bouyancy?

    i dont really know what all to ask but if anyone can think of things i might need to know it would be really helpful.

    thanks,
    jim

    Heya jiminey,

    Welcome to diving! (or soon anyway)

    Do you have to wear a WetSuit, No. Its really a matter of comfort, but wearing a wetsuit WILL add bouyancy to you.
    As fat muscle is heavier than fat the more muscle the better you will sink. The more fat the more positive bouyancy you will have.

    The dive shop was right, you shouldn't have a problem with the weight, assuming youre in good health and all, and diving will contribute to better health too!

    Believe me, Ive been diving with those MUCH bigger than you, heck they would make you look like Danny Devito standing next to Andre the Giant. Just as everyone does you will gradually learn what is the right amount of weights for you and you will end up doing just fine. Good luck and let us know how it goes!

    =-)

    Jiminey:
    While buoyancy control and such is possible, from your height and weight, it would appear that you are “a bit heavy” for your height. Such individuals should bear in mind the fact that some forms of DCS are the result of an excessive number of gas bubbles in the venous blood stream. These bubbles come from adipose (= fat) tissue in which nitrogen is very soluble. These bubbles can find their way, under some circumstances, into the arterial blood circulation. From there, they are carried to either the brain or spinal cord where they can cause neurological DCS.

    Thus, conservative diving is important. That means,
    [sp] slow ascents
    [sp] reduced no-decompression limits (NDLs)
    [sp] no strenuous exercise following the dive


    Good diving!

    I dive occasionally with a fellow about your weight, but lacking a few inches in your height. He feels that diving is the one athletic activity he can do without being disadvantaged by his weight. In other activities he quickly tires or becomes short of breath from the exertion of carrying all the extra weight.

    Remember, when diving correctly you are neutrally bouyant.
    That means you are essentially weightless when in the water. Doesn't matter whether you weigh 100 lbs or 500 lbs on land or in the boat, you weigh nothing in the water! Imagine the feeling of weightlessness when you're used to carrying 350 lbs around all the time. I'll bet you feel like a kid again.

    You may have a bit of a problem buying gear off the rack, but all gear can be special ordered in sizes customized to fit virtually any size and shape. Look around on any dive boat and you'll know that some of those folks could not have found their gear in a shop (ha, ha).

    Go for it, and get wet often.

    Jim,
    Let me first start by saying "Welcome to diving". Once you experience the beauty of the ocean, you're hooked. Size and weight will have little to do with your diving ability. I've trained several guys with similar proportions to yours. If there is one bit of advice you retain from these boards do this:

    Think about buying a weight integrated buoyancy compensator. Guys with your build usually have to combat a traditional weight belt because it has the tendency to want to wind up around your ankles... trust me this is not good. A weight integrated BC has specialized pockets that allow you to distribute the weights in the most optimized way possible. This will spare you most back pain and allow you to do a few skills more easily throughout your training process. It will also allow you to float with less effort on the surface.

    During your training your instructor will most likely tell you that the majority of diver distress happens on the surface, not during the dive itself. With a non-weight integrated traditional style BC, the BC will want to keep itself on the surface (while inflated) while the weight belt will want to see whats on the bottom.... Since the two systems aren't somehow tied to one another this could be quite awkward. Some students try to compensate for the problem by tightening their cummerbund, which does nothing but put pressure on the sternum, which in turn makes the student sea-sick. Nice huh?

    There are also safety related issues in favor of the weight integrated BC that can be addressed as well. Such as not having to deal with a weight belts tendency to want to hide the buckle (the belt likes to spin at depth). Plus the fact that a good weight integrated system won't come off unintentionally at depth. One other point is that a weight belt is a two inch nylon webbed belt that has all the weight on it, if you think about how your body is positioned while diving, the lower back isn't the best place to put that kind of pressure. A weight integrated BC on the other hand will distribute the weights throughout the length (app. 24") of the BC while diving as well as during the entry/exit process.

    Why is it that I knew you would eventually have a reply?

    Most of what you have to offer I agree with and feel serves somebody well. BUT, I'd hate to be at a party with you and try to have the last comment!

    Peace, but I couldn't resist.

    Ok - i know this was mentioned a while again now but I havent been keeping track of this thread!

    For years now I have been saying "fat floats" whenever me and my mum and sister use to go swimming - only joking about with them of course.

    From the comment King Neptune made earlier - it makes it sound true - is it really????

    Yes Abby, it's true. It has to do with Archamedis Principle and the relationship of the differing densities of your body composition. Everyone is unique in build, and therefore it's highly variable.

    This is primarily the reason why some people can sink effortlessly to the bottom of a pool and just lay there, while others have to fight to get the the bottom, and the moment they stop they bob to the surface like a cork.

    Cheers Mario

    Nice to know. I told you a while ago about my instructor friends and how they weigh me down - I think that says it all really!!!!!!!

    Judging from your pictures, it didn't look like you need to switch from Guinness to Guinness Light anytime soon. Then again I could be wrong... perhaps the 'towel' added a gram or two? LOL!

    And what's this about my ugly mug? If you think that's bad, wait till you get a look at 'ol Mad Dog himself! Yikes!

    ScubaBaby,

    You may be a little too young to remember but if you look back at the old atari video games you will see that If "Mario" is an "Original" that he is short, very hairy and is some sort of banana eating primate!

    KN

    I do remember the Old Mario games - i have a box at home full of all the little stupid things!

    Even if he is hairy and short and has a problem with bananas he is still sweet! Running round and that - very cute.

    And Mario S Caners pic is even better!

    I was talking to a friend about why the actually put so much weight on me yesterday.
    (After finding out fat really did float I was quite concerned about his opinion of me!)
    And he said that it's because I am a woman! Me not being to happy about sexism, jumped on him for saying it and then after I'd tried to strangle him with my "towel" I let him explain. :p
    He said it was to do with having "more air spaces!" Such as the fact women have wider hips therefore this space is taken up with air. Is this a true reason or is it still that they are trying to drown me???

    Dear Mr Jiminenycricket.

    Unfortunatly they haven't told you the truth about being a big guy and diving.
    As I said it can be a cold and lonely place.
    I myself am 6'4" and 113kgs. (249lbs)
    Doing most of my diving from boats I find that I and I alone get placed on one side of the boat to make it level.
    This leaves no one to talk to for the whole journey to and fro, while all those lettuce eating skeletons laugh and joke the whole way on the other side. I know they are talking about me you know. Please excuse me as I wipe away yet another tear. And the food they serve would'nt fill a flat snake. I mean you can't call 1 peice of chicken and a spoonfull of coleslaw lunch can you. :nono: Tip No1 take FOOD. Tip2 DONT share food.
    Shore dives put us on a slight advantage. Just sit back and watch the stick insects struggle with tanks and weight belts while bellowing Its too heavy

    On a serious note you will have a great time diving, good people and good times ahead.
    I find I dont get cold and only dive with a wet(lycra) shirt and my wetty long johns and that's in winter about 10 to 15 celsius. Can't remember when I last wore my jacket. Different folks different strokes. You should be able to buy a weight belt that will suit you they can cut it to your size. Tip No 3 put a plastic bag on your foot to make your wetty slips on easier, getting it off is a whole other matter. Don't let the bag blow into the water though.
    Tip No 4 dont go to crazy buying brand new gear straight away, try to hire or buy second hand first and see what you like and need first.


    BIG GUYS/GIRLS RULE
    Almost forgot to be politicaly correct.

    I noticed from an earlier post that someone sugested you buy a weight integrated BC. Although I find them very comfortable, you should find out how much weight it can actually hold. Some of the ones that use velcro to support the weight pouches WILL come lose during your dive, or worse, during your deco/safety stop.

    You should first get a second hand BC that is in good shape and that it fits, you may have to suffer with some of the more uncomfortable weight belts for the time being. As a new diver especially considering your size, you will use a great deal of weight to get you down. As you gain more experience, you will drop some lead off your belt and feel much more comfortable. Once you get down to about 10 to 12 pounds of lead, then you will want to look into weight integrated BC's.

    Welcome to diving, you will have a lot of fun and get a great cardiovascular workout at the same time. ;)
