Doesn’t the idea of a lovely three day sail in wonderful old boat sound nice? Here are a few things to think about before you sail away.

1. Do check the price. It may be possible to take an actual, fairly luxurious cruise instead of sailing on one of the oldest boats in America.

2. Do make sure you fully understand the size of your “room ” on the boat. If you are hoping to have any romantic action in your cabin it would be good to know ahead of time that you and your partner each have a small bunk and these bunks are not on the same wall.

3. Do know ahead of time if you and your partner can both even stand up at the same time in your “room” on the boat. If the answer is “no” consider other options.

4. Don’t leave without checking more than once to make sure you have Your luggage. Even though you carefully packed All the luggage, did Yours actually make it to the boat? If not you will have a fantastic time with no changes of clothing and nothing warmer than a sweatshirt. Don’t leave without all your luggage!

5. Don’t get on a boat where the crew is planning on having a lot of assistance from you and the rest of the paying customers. Like, for instance, doing your own dishes or pulling in ropes and such.

6. Don’t think you will get everything outlined in the brochure. Will you ever go onto land during this excursion or will you just ride around and around on the boat being quite sure you’ve seen that same shoreline five times in three days. Do ask the boat crew if you will ever see any of the sea creatures promised and what about the island lobster bake?

7. Don’t plan on real bathroom facilities and do ask where the shower is. Ha!!

8. Don’t even think of taking this kind of boat trip if you don’t like small spaces. Not only is the berth area minuscule, there is no other place to play games or cards except the galley, also tiny and often being used to fix the meals.

9. Do consider this boat trip if you enjoy working while on a very expensive vacation in the smallest accommodations imaginable while possibly seeing no sea life and not eating promised lobster!

These are some do’s and don’t of a boat trip I’ve actually taken.

Bluetooth devices will normally operate at 2.4 GHZ
in the license free, globally available ISM radio
band. The advantage to this band includes worldwide
availability and compatibility. A disadvantage to
this however, is that the devices must share this
band with other RF emitters. This includes
automobile security systems, other wireless devices,
and other noise sources, such as microwaves.

To overcome this challenge, Bluetooth employs a
fast frequency hopping scheme and therefore uses
shorter packets than other standards within the
ISM band. This scheme helps to make Bluetooth
communication more robust and more secure.

Frequency hopping
Frequency hopping is basically jumping from frequency
to frequency within the ISM radio band. After a
bluetooth device sends or receives a packet, it
and the device (or devices) it’s communicating with
hop to another frequency before the next packet is
sent. This scheme offers three advantages:
1. Allows Bluetooth devices to use the
entirety of the available ISM band, while never
transmitting from a fixed frequency for more than a
short period of time. This helps insure that
Bluetooth conforms to the ISM restrictions on the
transmission quantity per frequency.
2. Ensures that any interference won’t
last long. Any packet that doesn’t arrive safely
to its destination can be resent to the next
frequency.
3. Provides a base level of security as
it’s very hard for an eavesdropping device to predict
which frequency the Bluetooth devices will use
next.

The connected devices however, must agree upon the
frequency they will use next. The specification
in Bluetooth ensures this in two ways. First, it
defines a master and slave type relationship between
bluetooth devices. Next, it specifies an algorithm
that uses device specific information when
calculating the frequency hop sequences.

A Bluetooth device that operates in master mode can
communicate with up to seven devices that are set in
slave mode. To each of the slaves, the master
Bluetooth device will send its own unique address
and the value of its own internal clock. The
information sent is then used to calculate the
frequency hop sequences.

Because the master device and each of the slave
devices use the same algorithm with the same initial
input, the connected devices will always arrive
together at the next frequency that they have agreed
upon.

As a replacement for cable technology, it’s no
wonder that Bluetooth devices are usually battery
powered, such as wireless mice and battery powered
cell phones. To conserve the power, most devices
operate in low power. This helps to give Bluetooth
devices a range of around 5 – 10 meters.

This range is far enough for wireless communication
but close enough to avoid drawing too much power
from the power source of the device.

If you are ready to invest money for a future event, such as retirement or a child’s college education, you have several options. You do not have to invest in risky stocks or ventures. You can easily invest your money in ways that are very safe, which will show a decent return over a long period of time.

First consider bonds. There are various types of bonds that you can purchase. Bond’s are similar to Certificates of Deposit. Instead of being issued by banks, however, bonds are issued by the Government. Depending on the type of bonds that you buy, your initial investment may double over a specific period of time.

Mutual funds are also relatively safe. Mutual funds exist when a group of investors put their money together to buy stocks, bonds, or other investments. A fund manager typically decides how the money will be invested. All you need to do is find a reputable, qualified broker who handles mutual funds, and he or she will invest your money, along with other client’s money. Mutual funds are a bit riskier than bonds.

Stocks are another vehicle for long term investments. Shares of stocks are essentially shares of ownership in the company you are investing in. When the company does well financially, the value of your stock rises. However, if a company is doing poorly, your stock value drops. Stocks, of course, are even riskier than Mutual funds. Even though there is a greater amount of risk, you can still purchase stock in sound companies, such as G & E Electric, and sleep at night knowing that your money is relatively safe.

The important thing is to do your research before investing your money for long term gain. When purchasing stocks you should choose stocks that are well established. When you look for a mutual fund to invest in, choose a broker that is well established and has a proven track record. If you aren’t quite ready to take the risks involved with mutual funds or stocks, at the very least invest in bonds that are guaranteed by the Government.
