FWIW
1. most people with young families and jobs do not come into large sums of cash and abilities to buy a boat cruising boat. healthcare, parents disabilities, childrens disabilities, work problems, career changes, unemployment, underemployment, college costs...... anyone on this forum could easily come up with a list of "required family expenses". IF boating is not on your combined list now, it will not jump on later.
IF your spouse will not boat with you now on the nice boat, what chance is there that she and the children will join you later on a cheaper, older, smaller vessel.
2. If you current boat truly has that much value, convert some of the money into your house plans, and some of the money into a smaller boat you can use now. IF you love sailing, it will work. If someone in your household hates sailing, wellllllllllll Think about what kind of doghouse you want. perhaps old fashioned bribery is in order, a sort of quid pro float. Perhaps it is the perception that things are not balanced in expenditure of funds that adds to the boating aggravation, perhaps it is poor swimming skills, fear of water, or control issues. Whatever the reason,
3. The margins are too close. IF you absolutely need every last dollar from the sale of your boat, you should really look closely if you can afford or not afford the house either. And being house poor is no great shakes. Just how profitable do you wish to make Bank of america. MOst of us have owned houses and had children, Very few had no boat at all during the time they had those children. and all houses require more maintenance and upgrades......pretty much your entire budget will go there. just sayin.............
4. I used to have airplanes,,,,,,, I loved to fly and travel, even tho I was working plenty of hours, and the plane was paying its own way, the money was coming in, and we were taking quality time to enjoy the trips, and the children grew up learning and experiencing many of the wonders of flying and boating (Which both of them have had to stop during their college and family years) I got rid of the planes and settled on a general purpose water sports boat, that I could fish and cruise a bit with...........
long story short. Several spouses have enjoyed that boat.
IF owning a boat is unacceptable to your spouse, recognize it and make your choices with no complaints. There is no doubt one must choose a spouse over a hobby or passion. But if you have been given an ultimatum. do it eyes open.
5. Boats that are already paid off, are not as expensive as those you are still making payments on. I spend approximatetely the same number of hours a week on the boat as driving in my cars. guess which is easier to replace for me. I know a several people that spend less a month on a boat than their spouse does on booze and cigarettes.
Good luck and all the best to you in your next adventure.
p.s I still have that general purpose boat too. (sometmes spouses make their own choices)
