Buy the boat you want, life is too short. Either take out a loan if the rate is good enough, or if you had been thinking of a refi on your home, pay for the boat that way.

Let's see here... paying 2.25 - 2.75% (haven't looked recently) on a refi if you were going to do it anyway...

Or...

Paying cash for your boat instead of investing that cash, and losing out on 4 - 40% return on your investment?

The pride of paying cash can cost you money when you could be using it to make more.
