AICON 64..?

Well, it's clear the OP made up his mind before coming here. That's fine, proceed. He was waiting for one person to speak positively and finally one did in spite of others strongly negative. He's dismissed the negatives and latched on to the positive. I know nothing about Aicon. Just reading the thread and commenting on what I see. Proceed very carefully and I hope it works for you. I caution you though that you can have a sea trial and a boat survey and an engine survey but if you go into them with a mindset saying you want to buy, then you'll find a way to dismiss any negatives there too and may ultimately regret it. You're going to be paying for opinions. Be sure you listen to them.

I'd strongly value what Capt J, Mapism and Affrayed Knot posted. As to it having $150k spent on it or being unused or a great deal done it was, I consider all that to be sales talk and don't listen to too much of it. I don't know the price but the price of a discontinued line and especially the price in the US for a boat seldom seen in the US should be far below what you would think and if you go to resell it later, it will be even worse. Look strongly at how long it's been for sale in one of the best selling seasons we've ever seen.

Or how about looking at a top quality brand.....such as Hatteras?

Who knows what is a good price on a 64' Aicon because they're out of business, have very little following and built very few 64' yachts. I'd say a good price is around what a similar sized Jefferson would sell for.......or Meridian.....or Silverton.......close to the same size......

Someone please tell me the brand boat that is problem free. What are the areas that bring the biggest bills? Pretty much the same on whatever he buys except that paying the extra for a Hat or such may push him into an older boat with more hours which could bring on those big bills sooner. I would not buy a new boat from a company without a good track record, solid footing and a good support network. Once you're dealing with a 10 year old boat though the individual boat stands on its own. The opinions I'd be most interested in are about handling, performance and known hull problems. Save $100K or $200K and you can afford to do a lot of rewiring and such. Olderboater does make some good points though. 1) Don't talk yourself into any boat. Look with an eye toward why you shouldn't buy the boat or bring someone with you who can have that eye. 2) A lesser brand will be harder and probably take longer to resell. So make sure the deal you cut takes that into account. Make on the front end what you may lose on the back end.

LUXURY CUSTOMIZED YACHTS | AICON YACHTS

Seems to be again in business under new ownership.

The main reason I don't like new boats is the "new boat bugs", and they're why dealing with a solid company is so important. I remember when another yacht brand first showed up here. Getting paid for warranty work was a nightmare. However by a boat's 10th year I would expect most deficiencies to have been addressed either under warranty or by subsequent owners.

A website does not a business make.

So they've had a few designs developed and supposedly introduced one of those designs, the 66. How many have been delivered to customers?

And let's note that the CEO was involved heavily and a key board member and President of the North and South America group when the company failed and the Partner (and money man) is best known for SEC violations of price fixing and lobbying and other such activities.

So a new company perhaps or just vapor. I don't consider you back in business until you have deliveries to non related third party customers.

Assuming that the Aicon in question is the one listed for $785K in Stuart, it does seem that there are a lot of options out there in that class for quality yachts with better known, good reputations, even if you had to go a couple of years older (Sunseeker among them). I have learned not to judge a boat entirely by its listing (we all know that occasionally some are better than they show in a listing, many are worse), it is always curious to me when the myriad pictures seem to focus excessively on tablescapes (as in the case of the $785K Aicon) vs equipment spaces and critical details. Doesn't mean there's anything necessarily wrong and there's nothing wrong with one or two pictures of a well set table on the aft deck, but you have to wonder what they were thinking in this case.
Edit: it made me wonder if the boat was in charter and they were repurposing marketing pictures. After a quick search it comes up as having been offered in a fractional lease program as well as for "rental." Perhaps this is not the boat but there are many similarities to the OP's description. If it is and the boat was built in 2009 and splashed in 2012 as the OP mentioned, it should not be listed as a 2012 IMO. Red flag regarding honesty for me.

As has been well said, if pursuing this boat is where you have landed, just be sure to go in as "eyes wide open" as possible. As emotionally involved buyers we can rationalize negatives. Having objective, expert third parties you trust and are willing to listen to in the mix is obviously critical in any boat purchase of this magnitude.

I noted years ago at a boat show that the dealers wouldn't allow people into their engine rooms. The fact is that most are selling a lifestyle dream not a boat. Where the family will spend their time is more important to most buyers than what will concern a captain.
In regards to your red flag, if you look at the thread '2021 Global Order Book' you'll not that several of the yachts in production have been delayed due to the purchasers wanting a newer year boat. It's marketing. Most boats don't radically change designs one year to the next like cars. So the relevant date is the splash date although the Hull ID # could end up causing sellers to one day have to explain why they think an 11 y.o. boat should fetch what an 8 y.o. boat does.

You're convinced. Fine. You searched enough on facebook to find a happy owner. Make a reminder to yourself that the unhappy owners no longer own one. It's old history now.

As to why you don't see more answers of long time owners, there aren't many. Never sold that many and certainly not popular on YF. Didn't sell is why they're out of business.

As to every boat having their issues, that's a BS philosophy tossed around by those boat brands with more than their share. All may have some but some historically age better than others. For instance, Hatteras better than Azimut. Ferretti better than Prestige. Westport better than Vicem. The used market normally reflects those values.

Let us know how the survey goes.
