What exactly is a production boat?
All boats are 'produced' in some fashion - and no, I'm not being deliberately obstinate here.
My Irwin has Bob Johnstone's (Island Packet founder and designer) fingerprints all over it -
It's built to the same scantlings, uses the same hull designs types, chain plates and keel methods (concrete slurry with lead pigs).
It's not volume of hulls that defines it, more IP's are out there that Irwin's. Year for year IP also produced more.
My Gemini 105mc was "built to a price" point, I suppose you could say that makes it production - although the didn't start a hull until they had a buyer. The customizations I had included and added on while at the factory increased the price 13% - does that make it custom?
Now, I've been on a 1990 IP 38 - so I can see the difference in quality of workman ship, between it and my 3 year older Irwin 38 - no argument there.
Let's be honest here - that handcrafted rubbed finish don't mean diddly to the force 8 storm rolling in. It doesn't make the ride any smoother, the boat point any better - or TRULY affect anything more than the price of the boat.
I've also sailed on Endeavor's - another boat with Johnstone's ringers all over it.
And then too - I've sailed on Guiletta (former poster here) - as custom as a boat gets unless you specifically commission a NA. It's so custom it's one of a kind with it's modifications and only 3 hulls launched in over 10 years.
Guiletta's dynacell foam cored custom interior didn't do a dang thing to keep it from bouncing around on the waves like the 42 foot dinghy it was. It's a great short range cruiser, and a splendid racer; I'd not want it as it's too hard to sail by less than semi-pro's.
