Garages in High Risk Areas



In city environments like London and Bristol security is at the top of everyone’s list. This is no different when it comes to garages and storage. Garages in high risk areas are often cheap and affordable - but they hold a high price when it comes to chance. There are a lot of crafty fellows out there who will not hesitate a seconds thought to break in, steal and damage property if they see the opportunity. If you are afraid of this happening and are worried your property is at risk you can ensure this doesn’t happen with the right advice and precautions.
If you keep your garage in a high risk area chances are you can’t change the surrounding environment but you can adapt your garage to withstand attempts of a break in. Follow this advice below for peace of mind:

A stronger door
Roller garage doors should be your door of choice. They are industrial, strong and sturdy – a great defence against thieves. With a roller garage door the lock is much harder to break compared to an up and over canopy style. Made out of strong aluminium strips with a tough finish it can’t be kicked in or unlocked without a key. It would take an awful lot of effort for a chancing thief to break through this barrier.

Put steel bars in the windows
If you have windows in your garage you should either brick them up or put steel bars across them. A thief wouldn’t hesitate to put a brick through it if they believed there was a rich bounty inside for them. Thieves can also be crafty and agile getting through the smallest of spaces. No matter how high up or small your garage windows are make sure you remove the risk of an intruder getting in.

Install an alarm
If your garage is in a secluded you don’t want to run the risk of someone spending a lot of time breaking in. With an alarm in place someone will be sure to hear it and the loud sound itself will alarm your intruder.

Automatic lighting
Make sure the garage is well lit. If you have a security light outside that comes on when it detects movement you’ll eliminate any risk of having a thief sneaking around without anyone seeing them.

Install CCTV cameras
CCTV cameras do not come cheap but there are affordable alternatives out there. You can get fake CCTV cameras with a blinking red LED, your everyday thief isn’t going to risk snooping around to find out if they are real or not. Many thieves are repeat offenders so even if they are not doing much they may not be too please about having their faces on camera even if they come across as an innocent passer-by.

Thieves like dark, secluded places where no one can see what they’re up to. With these precautions you can help protect your garage from unwanted intruders. So long as you ensure you have a strong sturdy garage door and your garage should be safe. Luckily there are some great companies out there, whether you are looking for garage doors London or garage doors Bristol be sure to fit the sturdiest style available.

The way to Start A Boat Producing Hobby With Wooden Boat Plans

For all those that are just starting out inside the boat-making hobby, finding the ideal blueprints may make the difference amongst sticking for the process or abandoning it. Like most hobbies, it really is best that first-timers appear for wooden boat blueprints which might be difficult to create with no becoming too difficult.
Look For An Adequately Sized Model
Aiming to build anything also large would take a long time to finish whilst making one thing small would actually be harder. This can be simply because coming up with really modest components need precision which is not yet created in first-time builders. Choose anything that would easily be manageable without having becoming also ambitious. Don't overlook to constantly contemplate your budget when considering the size in the boat as well because the available space that would accommodate the process.
Pick What Creating Method Operates Ideal
There are generally two varieties of strategy when constructing crafts. The first is the stitch and glue strategy whilst the second 1 is the ply more than frame approach. Initial time builders should study every single a single ahead of deciding what technique works best for them.
Exactly where To obtain Wooden Boat Plans?
Wooden boat blueprints would be the most significant aspect of vessel developing. If one particular gets a poorly made blueprint, then the vessel itself would pretty a lot fail. That is why in terms of initial timers, it could be best to purchase a blueprint rather than get it free of charge. This way, they can make certain that they are obtaining a pattern that's completely created with sizes which might be accurate and simple to follow. Of course, receiving a blueprint for free can also be an option and there are in fact a lot of decent patterns out there. However, for top quality results, a bought set of plans would be considerably better.
Always Do The Math
Do not just rely on the blueprints all through the building method. Attempt undertaking the math too, measuring parts and comaparing them to attachments just before really starting to cut, attach or construct. This way, a person can easily spot mistakes and initiate alterations just before they turn out to be also huge to cease.
Must there be any issues throughout the boat generating process, do not be afraid to ask questions. The great thing about this hobby is that you can find already many enthusiasts enjoying it, therefore creating it effortless for first-timers to locate support anytime they have to.
It might look like a good deal of function, but like most hobbies, generating a boat from one's personal hands could be a quite fulfilling pastime.

High Tide


It is above the stone arch bridge, near the Duck Hole Farms, that I notice that I am the noisiest creature in earshot and then some.  Only when I pause my paddling do I catch on to the din that my paddle has been making with all the swirling and gurgling that comes from a power stroke.  It is quite a calm day.  It almost makes my ears hurt.

I put in near the confluence of the Neck and East Rivers just as the tide begins to cross the broad top of the even sinusoidal wave that describes tides in this area.  As I head up the Neck, I observe the vegetation and pilings just to convince myself that I have not misread the tide chart, as my car is parked not more than 3 inches above the water level.  The ebb is slow today and I paddle a short hour before I start to notice and inch of wet above the water.


The osprey nest that was built last year on a detached dock is below eye level and I stop to examine it.  It never seemed a secure location for a nest and I did not see the pair raising any young.  The nest is intact with an old sandal near the center and the carapace and wing bones of an unidentified bird left behind.  The bones are what I would expect from a medium sized shore bird...larger than a pigeon, but smaller than any duck. I suppose they could also be from a young osprey.  I collect them.

Cloud cover during the night kept the temperature warm enough and the wind that comes from the north is hardly worth the paper it takes to describe it.  I push some buffleheads up the Neck and then up Bailey Creek, but there is not much else for bird life down here.  The Sneak is broad at this tide level, so much so that it takes much less time to pass through as each of the kinked bends has been widened into gentle curves.

When I pass the highway bridge the bird life improves.  I flush mallards and some Canada geese and a good number of black ducks take to wing from the typically large distance that they customarily do.

I pass under Foote Bridge and over boulders that are well buried in the high water but I stop short of the jungle, the last 1/3 mile of paddling, because it is also half gymnastics.  The tide is now dropping fast and the current has picked up.  It will be an easy return.

When is high tide


Nerd alert—The word of the day is, TIDE!  Say it with me, T-IIIII-DDD-EEEEE!

It all started with a simple question--when is high tide in Georgetown, Bahamas?  On our journey south, Mother Nature gently taught us land-locked Missourians about tides.  In Annapolis, MD the mean range was 0.97 ft with fixed docks at most of the marinas.  By the time we reached Brunswick, GA the mean range was 6.6 ft with most marinas having floating docks.  In Florida, the mean range goes back down to 2.5 ft.  In the Bahamas, it is 3 ft (mostly fixed docks).  (The largest tides in the world are 38 ft in Nova Scotia!)

Definition:
According to Chapman’s the definition of tide is “…the rise and fall, the vertical movement, of bodies of water as a result of the gravitational pulls of the moon and sun…Tides originate in the open oceans and seas, but are only noticeable and significant close to shore...Curiously, the effect of tides may be more noticeable a hundred miles up a river than it is at the river's mouth because water piles up higher in the river's narrower stretches.”  (versus current which is the horizontal flow of water.)  

The effect of the moon:  When the moon is full, it is called “Spring tides” and have a greater range.  When the moon is quarter, it is called “Neap tides” and have less range.  As we learned in Special Report: What the heck is a perigean spring tide?, "When the moon is closest to the earth, it is called a lunar perigee.  The gravitational pull of the moon is the strongest.  Three to four times a year, the lunar perigee and full moon coincide.  This is the perigean spring tide (or unofficially, the supermoon or "king tide" in New Zealand) and can affect tides up to 20 percent (usually just a few inches).  Apparently, we experienced this once in Annapolis--when it's perigean spring tide, wind blows onshore from the bay and it storms (barometric pressure drop), they get flooding downtown." (See weather below)

The effect of weather:  According to NOAA, “we cannot predict the effect that wind, rain, freshwater runoff, and other short-term meteorological events will have on the tides.”
In an example, Explorer Chart's stated, "...the tides were running at least ½-meter higher than predicted schedules—that would be 1.5 meters above chart datum—Mean Low Water Springs. This was due to the Derecho that occurred in the Exumas on January 6, 2016."  In other words, the high winds had driven more water into the Bahama Banks than usual.

Explorer Chartbook further explains tides by stating, “[it is] part science, part art…Tides are seldom exactly like the predictions.”  and further explaining that tide is affected by local features with differences at cuts.  “Generally, the farther from the ocean, the later the tide.”

The tidal flow in our part of the world is generally a 6-hour cycle between high tide and low tide and changes daily.  There are generally, two high tides and two low tides a day.

I learned the term “rage tide” from the National Park Service kayaking website, while anchored at Cape Lookout Bight just outside Beaufort, NC.  http://www.nps.gov/calo/planyourvisit/paddling.htm 
“Most paddlers will want to avoid the rage tide, the time when the current flows the hardest, as ½ of the total water volume passes through inlets during the third and fourth hours of tide flow. During this time, flatwater will turn to whitecap waves and intermediate terrain can become expert.”

This is further explained by the Rule of Twelfths:  Per Nigel Calder's Cruising Handbook, you can use the Rule of Twelfths to approximate the state of tide.  "This says that in the first hour after high or low tide, the water falls or rises by one twelfth of the total tide; in the second and fifth hours, it is two twelfths; and in the third and fourth hours, it is three twelfths."  This also means that the hour before and hour after, you are still relatively close to high/low tide.

What are tide tables:
According to Chapman’s, The National Ocean Service (NOAA) is responsible for surveying and publishing the computer-generated Tide Tables which are “…PREDICTED times and heights of high and low waters for each day of the year at a number of important points known as ‘reference stations.’”.  This information is available for free at http://tidesandcurrent.noaa.gov

More examples of tide information:
Navionics e-charts:  “Our Tide & Current data are predictions based on the government Tide & Current Stations (including many different sources, which are proprietary information)…Please note that the Tide & Current information do not take Daylight Saving Time (DST) into account, so during this time period the predictions may be off by one hour if the device settings have not been adjusted for DST.”
Garmin BlueCharts: source unknown
Explorer Charts:  pg 72 Bahamas Exumas.  Nassau tide tables, “NOTE:  this data may differ slightly from the Bahamas Dept of Meteorology tables due to different source data.”  They also give a correction range for the Bahamas of Nassau -0:13 to 0:30 (source:  Bahamas Department of Meteorology)
A Cruising Guide to:  The Southern Bahamas by Stephen Pavlidis
A Yachtsman's Guide to the Bahamas
Bahamas Department of Meteorology (bahamasweather.org.bs) daily weather forecast
bahamascruisersguide.com 
The local net (usually references local knowledge)
OR:  the book Passages South, The Thornless Path to Windward by Bruce Van Sant, "Near open ocean you can assume high tide at 8 o'clock local time on the day of a full moon.  Add 52 minutes a day thereafter and do without tide tables forever!"

So when is high tide in Georgetown, Bahamas?  
It depends on who you ask.  For example, on January 16, 2016 (departing Red Shanks anchorage):
11:15 am Navionics chart plotter gave high tide at “Exuma Harbour” 
12:18 pm Pavlidis Appendix E, Nassau 12:38 - 0:20
12:37 pm Dept of Meteorology (“Exumas”)  = Nassau -0:01 
12:38 pm Yachtsman’s Guide to the Bahamas = Nassau
12:45 pm Garmin at “Steventon” (“14 miles from chart center”—North, Nassau + 7)
12:53 pm BahamasCruisersGuide.com  (Nassau 12:38 + 15)
12:58 pm local & charter captain (Nassau + 20)
1:21 pm The Net says Nassau 12:38 + 45 
(Thornless:  The next full moon is Jan 24, so high tide should be 8:00 if "near open ocean". NOAA has high tide at Nassau as 7:51)
That’s a 2-hour difference!  A local told me that high tide can be different at either end of the harbor. If you use the Thornless explanation of "near open ocean" this makes sense. The Northern entrance is the Exuma Sound (very close to the ocean) and the southern cut is very shallow water ("the banks", 11 ft) 

Why do I care?
Anchoring:  While anchoring, we need to know where we are in the cycle. Do we need to factor an additional 3 ft into our depth while calculating our 7:1 scope?  Or will it be 3 ft less under the keels than what our depth finder is reading? If there is a Supermoon or derecho (1 meter = 3 ft x 7 = 24 ft) it could be the difference between dragging anchor or not dragging (ask the catamaran next to us in Lake Worth!)

Skinny water:  Many cuts can be shallow, requiring a high tide to safely navigate through. (Others can have a significant current, requiring slack water to be navigable--another topic, but you definitely do not want to transit during the rage). The ICW also has areas that silt in, requiring high tide to avoid going aground (until it can be dredged again). Some excellent anchorages have a shallow entrance, requiring high tide to enter, but deep water once inside (RedShanks).

At a dock:  If you are at a fixed dock, and tie up at low tide, lines have to be secured with the idea that the boat will rise 3 ft at some point (usually in the middle of the night) possibly straining lines, stanchions or fenders.

Clearing bridges:  Our catamaran (47 ft mast) was in winter storage at a primarily-powerboat marina, with a bridge height just before the entrance of 53 ft. Our visit to the Albemarle Sound had us scooting under the Plymouth, NC 50 ft bridge to ride out the remnants of a Tropical Storm at the sheltered and free town dock.

The moral of the story:
Question your chartplotter.
Question the tide tables.
Confirm the location of the tide info given.
Confirm the source of the info.
Take into consideration the moon phase and weather (especially barometric & wind)
Take into consideration the range of tidal swing (2 ft or 8 ft?)
Compare the depth finder to your charts
Compare the depth finder to tide table
Keep a log
Look around--not just while anchoring but frequently throughout the day to get a feel for the area.
Ask a local fisherman or charter captain:  I've tried this and I get a lot of shoulder shrugs. "It is, when it is." Here's how they do it: visually.  Look at landmarks, pilings, limestone (water marks), sand bars/reef, slime on the side of buildings (visible?  low tide.  Not visible?  high tide)

We've also been known to stand on our stern step and attempt to "stick the bottom" with the boat hook.  We've also snorkelled down to take a look--in very shallow water, we can approximate how much water is under our keels or even stand up!

Don't get me started on low tide vs slack water.
