Thanks guys, but I don't have low blood pressure. Yep it was low in Dallas when they got to me but normally it is ok and in fact it has started to creep into the high 120's the last couple years. Isn't getting old great :wink: .

Joe on the other board suggested that I might try some of the anti-sea-sickness stuff before going ashore. So far I've never been sea-sick but did buy some over the counter stuff so might try it before I go in later.

I was thinking last night that since I've been aboard, March 9th, over 40+ days ago I've only actually been off the boat on shore for maybe 8-10 hours max in that time so need to get on shore more. During those days there has probably been only a couple hours the boat was never rocking to some degree so my body is really use to that.

About Bob's comment on looking like you are drunk that did happen when Ruth and I took our first trip to Florida. We had been on the water a couple weeks and a cold front was coming so decided to put the boat in a slip at Jensen's on Captiva and stay in one of their cute cottages. We tied up and were taken on a tour of a couple cottages and in one there were a couple ladies still cleaning. I walked around and couldn't walk in a straight line. It was kind of embarrassing as it was about 11 in the morning and I'm sure they thought I had already been drinking :o .

When I have the episodes on shore I get a little anxious thinking back to Dallas and need to get past that which I am 95% of the time. Russ the tech in Florida since my batteries should be good for 9 years after he turned things down a little. I hope so because I don't look forward to getting cut open to put new ones in but hope I'm around and they have to do that :wink: ,

I took a Dramamine today before going ashore and felt a lot better. Not 100% but way better than before. So I thanks Joe (on sailboatowners.com) for the idea. I walked around a lot and ate some really good Snapper at Edgewater restaurant/bar even though it took a long time coming but I had nowhere to go. I felt better about the place after seeing all of the locals that came in while I was waiting to pickup phone-in orders.

So today I waited for the slack water to to in and go through the narrow opening into the Lake Victoria but of course hit the incoming tide leaving and I can't believe the current under that bridge. I had the 3 1/2 HP wide open and hardly moved through it. Not near the waves outside so didn't get soaked going to the boat.

Image

Notice the depth of the back of the dinghy above as it gets into the current and he has to give it some gas and it sinks and the bow comes up. Now...

Image

... as he is in the current and on a lot of gas the back goes down even further. It is an interesting ride through there with the current. Right now the tides are running a little over 3 feet and all the water to fill and drain Lake Victoria on those 3 foot changes goes under that bridge.

I was going to drain the carb this morning but it started right up but then died a couple hundred yards from the boat like it was out of gas. Got it started and ran it a lot harder and it never died again. I did drain the carb when I got back to the boat. I'm thinking there was some water that was plugging the main jet at part throttle and when I finally ran it WOT that it sucked it through, just a thought and I'll never know.

I ran out of money, what I took ashore, so will get more from my stash and go back in tomorrow and get more groceries as they have a well stocked store right at the dinghy dock. I also found this little general purpose store that had about two to three times more merchandise that what looked like would fit in there. The aisles were very narrow. They even had a weight belt so bought it and one 3 lb weight. Anyone have any idea how much weight I need with a full suit and with a partial suit (short legs/short arms)? I'd bought another belt and some weight some years back but not sure where it is, probably on the Endeavour. Most items on these islands are very expensive compared t what we are use to paying but they had fairly large SS carabiners for less than I' found in the states so I bought a couple as I use them on everything.

I also got water from a spigot on the dinghy dock and a lady and her husband that were there, had just got to Georgetown, asked if she could test it for salinity and I said yes and she pulled out a tester and put it in the water and said that if was good at 300 something. She said under 300 was better but that this was fine. Thought that was interesting. Not sure if I'll need to drink the water or not. I started with 62 gallons total with 12 of that being water from the grocery store in the 2 1/2 gallon and 1 gallon sized containers and still have 33 1/2 gallons left at the moment. I drink as much or more than I use for washing dishes and sponge baths. I could of probably made the whole trip on what I started with but tomorrow will fill up 2 other 4 gallon containers and maybe use some of that for washing cloths if I don't do that at Rocky Point. I washed cloths twice with rain water from inside the dinghy (had some salt water in it) and that worked well but I had painted the dinghy flooring with some blue paint and it is coming off in little specks in the saltwater environment so had the blue specs on the cloths and towels so probably won't wash like that again, at least not the towel,

Sumner,

Congrats on another great adventure!

As are many, I am enjoying living vicariously thru you right now and look forward to your posts!

I happen to be a free diver and may be able to help you with your weight belt question...do you know the thickness of your wet suit (probably 1, 3 or 5 mil)? Is it a farmer john style? Are you weighting the belt to snorkel/free dive or for scuba (the weight difference is big between the two styles)? And are you using snorkel, free-dive or scuba fins? Last one...are you "heavy" in the water or buoyant naturally?

Stay safe and keep the adventures coming when you can...while relaxing along the way! 8)

Thanks this would be to free dive with either the shorty suit or with just the vest where I might not need any weight. I just want to be able to get down to say 10 feet when I want to. I use to be a really strong swimmer but age has taken a toll on that. I got the full suit for western waters in the colder months if I needed to dive on the anchor and did once and could barley get down 10 feet with no weight.

Full (head to feet) must be 5 mm as it is heavier than the shorty but can't find it on the suit.
Shorty (arms and legs) is 3 mm
Vest is 2.5 mm
Shorts that I also have are 1.5 mm

I'm 6-1 and probably 160 now, was 155 a couple months ago so still might be that. I've never been able to float with much more than my mouth out of the water being lean but with any of the suits I can easily. I'll be using a snorkel and fins sometimes, don't really like them. I know when I bought the other belt that I can't find I think I got about 4 weights with it but never used it. They have a couple more 3 lb weights at the store but I only bought one but will go back in tomorrow, might leave here Sunday, probably Monday for sure and won't have another chance to buy them. I'm thinking I'd test things in shallow water at first. I wouldn't mind having the weight for the full suit but hate buying it if I don't have to since I'll find the other belt and weights when I get back. So for now weight for the shorty suit and just the vest is the plan. If you could get back on this tonight that would help a lot. I need to go in tomorrow around 8 am to work the tide right at that bridge,

Thanks,

Sumner

Sumner,

For the depths (10-20ft or deeper) that you are going to...in an abbreviated suit or light suit...to free dive...2 lbs (for 1mm) and up to the 2-4 lbs would be about right (for 3mm of protection)...so your 3lb should be good...add scuba gear and you are in the 4-6lb range.

When you throw the full suit on (5mm plus ish)...you might be in the more 4-5 lb range to free dive....add scuba tanks/gear and you are likely in the 6-8 lb range.

In both cases...the smaller/less effective the fin...the slight upward (1lb) weight adjustment may be needed...just have your quick weight release procedures rehearsed as you practice in 10' or so of water as you find the optimal weight for you. The 3 lb weight you have is a solid middle ground...I'd try to pick up 1 more (only if you scuba) or optimally 3 more 1lb weights for free diving so you can fine tune a pound or two as you dive at different depths and temperatures. Also, fishing weights (1-5 oz leads) can help in a swimsuit pocket.

Hope that helps...remember to spend 2-3x (3-4x age adjusted) as much time on the surface as you do under the water to prevent shallow water blackout (can happen to the best/fittest swimmer/divers in shallow water)...time yourself...important, if basic. I also always deploy a long (50-100'), floating driftline with a float or life jacket on the end (cheap, yellow polypropelene works great) behind the dinghy/boat for unknown current/wind divergences or fatigue/cramps (you can't swim hard enough when you/the boat are going opposite directions due to wind and current effecting each player differently)!

And remember...have fun!! 8)

Fair winds and great diving!

Thanks,that really helps and they did have fish weights there so I'll get a few and appreciated the rest of the advice. Never knew about worrying about time under water in shallow dives,

Huh, I have lived years in the dive capital of the east coast and never heard of that Swb until now.
Will def. take it easy scrubbing the bottom of the boat after reading up on it. Was just out there last week doing just about everything the warnings say not to :?

All,

Glad to contribute to a great community of sailors that's given my family so much of their time and experience! :wink:

Our free dives here are frequently in the 80-120' with about 2 minutes on the bottom spearfishing ...so we are deliberate in what we are doing...but Shallow Water Blackout (SWB) (latent hypoxia) can kill you in 10-15'or less (and in the Bahamas/Keys...30' can look like 10' and you can 'reach' for the bottom and get in trouble too)...so be careful while having fun!

Here's a good link on SWB:

And a technical link for those of you who want the science:

Fair winds and safe diving!

Hi Sum,

Some of the most beautiful coral formations are located in little cuts where substantial current runs at all times except for dead slack. You can safely snorkel in those strong currents by using a technique called "drift snorkeling". Simply attach that long line to your dinghy, like Fishstalker suggests, and then attach the end of the line to your waist. You can then get into the water, snorkel over the great coral gardens which favor places with strong current, and then when you're finished with your drift, pull the line in to retrieve the dinghy and climb back in. That can be easier said than done. A boarding ladder is helpful. Lacking one, you can fashion a help with a short line in the water and a loop large enough for a foot at the end.

Chinook,

Thanks for elaborating on that part...very safe way to snorkel! I didn't mention this part as Sumner is likely not spearfishing in the Bahamas (illegal), but for those of you who may give it a try somewhere...and perhaps helpful to Sumner to visualize the possibilities since he may be doing some solo exploring/boat maintenance in current/wind...

I actually use my dinghy in the manner Chinook describes so well, with me not attached, but holding a short (10') line (when free diving/hunting...I would attach if just snorkeling) while scanning for targets on the reef at the surface and drifting with the dinghy. Then I have a 100' float line off the back of the dinghy in open water (for wind /current divergences) and attach my gun to the dinghy via a 2nd long (150'), 200lb fishing line (looks like really thin rope, not clear fishing line).

That way if I spear something and there are a lot of sharks in the water or it is a big fish that will take some effort/time to land and I am short on breath...I can just let the gun/fish go and recover both from my dinghy (spear is attached to gun by coiling wire...think phone cord style). Thus, my dinghy acts as a float buoy to tire the fish (tuna in deep water)...and I can catch the dinghy via the float line off the stern.

Thanks for describing that. I'll try it. I've probably been overly cautious but have read of people getting separated from their dinghy's in the water and swimming off the Mac in the Keys I couldn't believe the currents where you thought there should be none. I'd have a line of the stern and swim up ahead of the Mac while it was on anchor. Being alone isn't the greatest safety wise and I'm aware of that so to this point just swam in protected bays.

I'd bought some video cameras that weren't that much to use on the race car and they came with holders to use under water and I'd like to try them out.

Thanks for the help on this guys,

Sumner

One of the best places to try drift snorkeling is near the little cove we anchored at on the south end of Hawksbill Cay. I'd spotted a notation on the chart labeled Coral Garden and we had to check it out. It was incredible, however the current running through the cut between Hawksbill and a small rocky coral islet scared us. I hadn't learned or thought about drift snorkeling while tethered to the drifting dinghy at that point. It would have made the experience much more enjoyable. If you get the chance, that anchorage is one of the prettiest we stayed at during the whole trip, and we had the place all to ourselves (another instance where the shallow draft Mac can get you in to places other boats wouldn't dare attempt. Good luck with your cruise back up the Exuma Chain. I hope the weather will enable you to stop and savor, when and where you wish.

Sumner,

I've been a SCUBA diver for just shy of 40 years and I fully concur with fishstalker on the weight recommendations. You said that you normally float in the water with your mouth just above the surface. That would mean you almost neutrally buoyant at the surface without your wetsuit. When you are neutrally buoyant you will neither rise nor sink in the water. That is what you are aiming for with your wetsuit on as well. When you are properly weighted you will be able to float vertically at the surface with your chin just touching the water while you are breathing normally. The weight belt is not supposed to pull you below the surface. It is just there to get you back to a state of neutral buoyancy. You can do all of your testing right next to the boat.

Being neutrally buoyant means that you wont have to expend extra energy (oxygen) just to get below or remain below the surface. Once you get down a couple of feet the air bubbles trapped in the neoprene of your suit will begin to compress and you will get less buoyant the deeper you go. At the depths that fishstalker and I dive that is a significant factor. At the depths you will be diving you will just notice that you won't have to expend any additional effort to stay at depth after the first few feet.

Stay safe! Don't hyperventilate (intentionally or due to stress or exertion), stay calm and begin with a surface dive. Your legs should not really be anything other than a weight to push you below the surface until your head is about where your feet started out. I can see from your pictures that you are not carrying a lot of extra "insulation" but for short dives you might try not using the wet suit at all. I seldom use one in the Bahamas. My only concern in suggesting it though is that the wet suit will give you immediate positive flotation if you drop the weight belt so you will be losing a bit of a safety margin if you are not also using a snorkeling vest.

I look forward to your updates. I've been planning a trip to the Tortugas recently and I was pleasantly surprised to see that we picked a lot of the same overnight spots going down the west coast of Florida. The Bahamas won't happen for me this year but I will definitely be going over your logs when I do. Thanks for sharing your experiences.
