Well, as a poor lowly public servant, I had to take a more conservative approach than most. I waited until I could pay cash for both boats I have owned.
The wife and I do fairly well for our area at just over 150k a year combined. We have a fair amount of cash in savings and I put about 20% into my pension and 457. The wife is also contributing to her 401k.
I would have a lot more disposable income if I didn't live with 3 princess' (wife, daughter, and yorkie) that have no clue how to spell "thrifty" or "fiscal responsibilty".
But we love our boat and will have another bigger boat as soon as we can afford it without a payment.
