People love to bash things on the internet. I don't like the new 22, but's almost certainly not going to be around for long so it's NBD. I thought the 26SH was a great boat, but the price seemed very high (not much less than a Regulator 26XO), hence they're not being made. The 22 will probably be the same, though I really don't understand why Parker is having such a hard time making new boats that are priced reasonably.
The meat of the Parker line up seems to be the pilot houses, and it doesn't seem like those are changing (if anything, they have made small improvements that make them better, like the changes to the transom, adding color to the hulls, better color schemes for the fabric, better looking console set ups). I know some people liked the MVs, but they were strange boats that seem to only appeal to a very narrow category of boater. I have a 2300 and think it's the best big 23 on the market (for the price), and I don't understand why they didn't sell well, but the fact is that they didn't sell well, so Parker did what needed to be done. As long as Parker doesn't mess up the big center consoles or the pilot house boats, the world will go on. Side note: they keep talking about getting away from wood, which I think is bullcrap and a cheap cost-cutting scheme, but as I understand it they continue to use the wood stringer system. I'll be curious what they do in the future, my guess is that there is a lot of infighting in that company as to the correct direction to go.
