What is the difference of a boat value, let's say from a boat (everything is the same) from year 2000 to 2002? or from a boat 2006 to 2007? How much does a boat depreciate per year? roughly.
Or for example, A new boat 2014 is worth say 200K.. What would a 2010 same boat would worth? All things are eq. HOURS, ETC.

Depends how old the boat is. Older, clean boats have already depreciated and won't lose their value as much in the same period of time vs a new boat.

I would guess new boat depreciation is more-or-less the same as with new cars, but maybe not quite as bad....

I'm LOOKING FOR A PERCENTAGE OF A SORT. Let's assume it is 2002 now. How much a same boat year 2000 would be worth, in 2002 (book value if you will) I know in 2014 they pretty much the same. But there is got to be some percentage loss from year to year.

I dont think there is an exact percentage that a boat appreciates from year to year. Boats no matter what year is only worth what someone is willing to pay and how bad they want that particular boat. Year to me only comes in to play when banks get involved. An asking price is just that a asking price.

Your question has no easy answer. Older boats with highly desirable engines and low hours are worth more. The new boat sales crash 2007-2014 changed any generalized depreciation rate in force as some used boats actually gained value during that period since new ones were not being produced.

Exactly.

Also, a year 1985 boat is going to depreciate very little from 2000 to 2002, assuming it's in good shape. A year 2000 boat is going to depreciate a TON from 2000 to 2002, even if it's still in fantastic shape. Depreciation diminishes year to year over time.

I gotta agree with the above, there really is no answer to this. Even the best guess would have such a margin of error it would be useless. Brand of boat, is it 100% OEM, where it was used, options, ?. . . . . . heck even color and where you are at in the country, the list goes on. There are only two things that determine the exact value of a boat. What you will take and what someone will pay. When those two lines cross on the graph you have the precise value of a boat. Sorry no easy answer Peter i know you are shuffling around your personal fleet at the moment good luck with it you really have a nice boat.

^^^^^^ Everyone above has it covered.

Hi Paradox,
I see your point at trying to determine a value or depreciation on 2 older boats, just a years apart in comparison (both being identical in overall set up, hours, condition, etc).
If the boats are basically the same without model year changes or technology improvement.. values would be similar within a few percent depreciation , in my opinion.
Boats are so different in the resale market natiolally compared to vehicles because it is a specialized market + there are so few for comparison . Typically there may be a only a few available used (of the same boat) or maybe one for sale of an exact model or a particular rigged boat.
I see depreciation a litte greater the first couple years ,then the values slide gradually thereafter., its hard to give an actual percentage.
Also it is hard to give a depreciated value because asking prices used vary quite a bit these days and who knows what the actual sale price finally is.

you said..."Or for example, A new boat 2014 is worth say 200K.. What would a 2010 same boat would worth? All things are eq. HOURS, ETC."
I would think that 2010 boat is worth about $150K IMO (assuming the 2010 is a superb showroom example)

That's about 6+ percent depreciation per year...

I am in South Florida and the market is unique as there are many boats of all types , in operation all year long. If we add salt water to the equation then that better supports the depreciation stated above. The variable can change a lot, location, use, how it is stored,..etc..

Hope this helps, have a great day on the water !! isn't that the original plan!!

I appreciate the comments. Thanks. But some of you missing the point. The question is depreciation as it relates to time. Not what is any boat worth, or can be sold. No price comparison is involved with location or model, color etc. Assuming that all is equal, to one year to another. There is a concept called "future worth of money" in the finance world. I understand the concept, and trying to put in something in a mathematical form. xxxxxxxx1 sort of hit it on the head. NADA, shows some values. No matter what the boat will be sold, or how much one would willing to pay, but there is a math. NADA shows a value of 15k for a 1991 boat. No value for 1995 since there is no DATA for the 1995. Only a few were made, no records. So, if a boat depreciates x % in the first year. Y % in the second year, Z% in the third etc. what are the percentages? I know it's a diminishing formula, so I guess, this might work. 10% first year, (may be more, in my mind) 7% next year. 5% third year. 2% 4rt year. hardly any change after. so if NADA shows 15K for 1991, based on this a 1996 boat value in 1996, should be 18k. +- in 2014, both 1991 and 1995 boats would be worth about the same 6-7K. I'm not asking current values, I'm looking for the math of depreciation or the future worth of something based an diminishing returns.
