There's wisdom in both. Selling now and restarting the adventure when the future looks brighter. But also weathering a dry spell by storing the boat for a bit (if you can find a place to do that for free).
There's some value in the boat that you can realize by a sale (more than 28 cents) but on the other hand, it's also not as much as for a big boat - I don't expect you can actually live off such a small amount of "capital" for any extended period. However, I can see why you would want to make sure it's not a drain on your finances either (so no paid storage).
You were fishing for sympathy, but, a little bit, I suspect, you are also fishing for opinions to help you rethink, or validate, as the case may be, your decision. So, here goes:
I bought my DS when the second kid was under way. It proved a nice way to give the mother many summer afternoons of peace by herself. So, that first season, it saw a lot of use.
The DS is a great boat to sail with small kids - if done prudently.
Later, there were some years where the boat hardly made it into the water (too busy with work and/or family). I believe three times per season was the lowest count. All I spent on the boat was money for a new tarp. But afterward, I was able to ease back into regular sailing (and maintenance) without the need to first go shopping for a boat. It was nice to not have to start at square one, and to be able to get value out of the initial repairs and, in my case, trailer restoration, instead of loosing all in a sale. (Hard to get your money's worth, other than by enjoying the results yourself).
That would be my take on this question, even though I appreciate that everybody's situation is different.
There's one situation where I would counsel you to sell and get a different boat, and that is if you find a group of people to sail with (against) and need a different type of boat for that purpose. (Disclaimer: I have two boats now, for that reason, and because my original purpose for having a DS for pure day sailing hasn't changed - but that's not a solution that I would recommend - it has it's own complexities). Nothing is better than sailing, except sailing with a group of good friends.
