First a couple easy, cheeky suggestions that I am surprised to have not seen anyone mention above. Then a bigger idea that will work wonders for some of you ...
1. Stop drinking at bars. Seriously. Pay attention to how much money you spend at the bar on alcohol every time you go out. You don't have to stop drinking (although you'll likely cut down somewhat) but just stop handing all that money to the bar. Get your cheap vacation-saving ass a hip flask if you want to go out. :: $50-100 per week turns into $2500-5000 / year.
2. Stop smoking. Seriously. Do the math already -- a pack a day habit will pay for a nice vacation in a year. Do I have to mention the health benefits? Your air consumption will improve as well, so your dives will be longer and more enjoyable (more fun for your money). Smoking is also a factor in a large number of diving related injuries and fatalities. Do your self and your loved ones a favor and quit already; you've probably been thinking about it for years. Reward yourself with a vacation at the end of a smoke free year. :: Right now, a pack of cigarettes in the US costs between $5 (Kentucky) and $15 (New York), yielding somewhere between $1800 and $5500 per year in vacation savings (to say nothing of the medical savings later in life).
Right, so that's anywhere from $4300-$10500 per year just from (1) and (2). So, here's the big one that could change your life (as if quitting smoking and drinking in bars hasn't already) --
3. Next time you get a raise at work, just pretend you didn't. Don't start spending it, just carry on like you never got the good news. Adjust your direct deposit to shave that extra money off the top and put it into a separate vacation account. As the money accumulates, use it to buy 3, 6 or even 12-month CDs with higher rates of interest on a regular and recurring basis. Consolidate the CDs when they mature with the excess money in the account and buy another CD. If you are clever, you can stack them in such a way that you have liquid capital available in the account every month (for OMG, EMERGENCIES or for a quick last minute trip that has come up), with larger amounts becoming available every quarter, every six months and every year. This takes some discipline to manage, but establishing a CD ladder like this is a very effective way to increase the interest on money you are saving while keeping it more liquid than if invested in a single CD. Make the effort to adjust / reinvest your CD ladder part of your monthly bill paying routine. It will be come wrote, for the most part, and once you are familiar with the process it will be relatively quick and painless. :: I don't know how much your salary is but most people with this hobby have decent jobs with decent incomes and their annual raises are likely measured in the thousands of dollars. Put it into your vacation account... You deserve it.
