Please tell me it is worth it???
My questions to you are: What are your priorities, what are you loosing? Junk? And is it just you or ALL of you that want to cruise? A house divided will not stand! A vessel is a sailors true home!
As one of the other readers stated "Move to another city" where you can sail on a regular basis and even spend the weekends on the vessel. Also I would suggest keeping a trailerable vessel (for now until you decide) that only costs you for minor up keep and it''s use, assuming that the 25'' Catalina is on a trailer. A vessel in the water assumes more maintenance and money.
Living aboard saves money but how much room do you need? Aquiring things will run you right out of a vessel. Can you all live on just the necessities. Cruising is the same as living aboard but water, food, power and money are not at easy to acquire.
But, at least you are asking the right (experienced) people! You just have to really get truely involved to find out if it''s for you all!
