Kudos to the original poster.
Sorry if what follows seems pedantic.
From my perspective, ( a Ph.D. in Finance) the imminent economic situation (2019-2020) is not good. Economic systems reset regularly, the duration/intensity being the result of causal factors. The more 'structural' the cause, the worse the reset. The last recession, while bad, was actually minimized by the world's reserve banks flooding capital markets. At effectively zero interest rates, there was a massive wealth transfer of savings to corporations and the very wealthy.
After ten years, there is no longer a high probability of the next recession--it is underway at the moment. For those wanting 'proof', the evidence is abundant: look at the major international players (China,
Germany, US, Japan). However, you will need to do this outside the mainstream media. I say this because of the dominant political agenda. There are any number of websites/blogs with good insight into what is happenning.
The only question is how bad it will get. For most of us cruisers, our
income depends on
retirement funds, 401K, pension plans, social
security etc. Given the 'evidence' I am seeing, I worry more about those failing than the 'value' of my
boat. Do not think social
security is guaranteed. In an economic crisis, everything is on the table.
Possible outcomes range from more of the same:
Reserve banks continue QE (quantitative easing), flooding markets with even more low interest debt. The result is low GNP gains with massive increases in debt. This will only postpone the inevitable, or result in a prolonged period of very slow recovery.
to a massive global implosion.
Other than buy gold as a hedge, or invest in real, incoming producing assets there is not much you can to do except tighten your belt. Imagine a structural collapse of banking, currencies, etc. with so much debt outstanding that governments are unable to do much about it except flood the world with more fiat money--think inflation. Another reason to buy gold/real assets.
Now, I've done my doom and gloom thing, to answer the original poster.
Asset values (your catamaran) will fluctuate based on demand and supply, and the rate of currency exchange, itself the result of demand and supply for the exchange currencies. Factors influencing exchange rates include relative inflation, interest rates, real GNP growth, various risk elements, and so on.
If I was trying to avoid the issue you raise, I'd buy gold as a store of (perceived) value and medium of exchange. If you had a
monohull, you could store it in the
keel.
