Re: can I afford to continue sailing
Something you can try is finding out if your marina will do half seasons? You can launch her in July and might save close to half. I know some marinas on Lake Michigan will do month by month slip rentals too.
We had to take a break for 3 yrs from boating until the $$ was saved and it made since to do it again. So maybe think about taking a year off?
As some have mentioned already, take your family vacations on the boat. Instead of flying to Disney Land or spring break in FL. That alone will save you more than enough to keep the boat in the slip.
Anyone here giving advice on how to deal with your wife is just silly. You know her, they don't. Do what's best for your kids. I the end they are all that matters. Not you, not her and certainly not the "BOAT".
