One of the lucky ones.... Just sold my boat looking for another!
Talked with the guy who actually built the boat I've been looking at. It's extremely light and is made of vinyl ester (sp?) I was also surprised at the cost to build another one as he's got two in the works. The motor hours are unknown. He also said the boat is extremely fast and basically on plane when you put it in gear. Downside is if it makes up you gotta drop below 12 knots cause it will pound. Any thoughts?

They all pound if you do not run them right. I would est that to get a 30 Duffy to pound and 12 knots would take 6-8’ from the NW and stacked up real tight with daylight through the tops of each curling wave. The 35 Duffy is probably the best head sea DE ever made in that size. Granted the 30 is much smaller but I am sure all of the qualities stay the same only in less proportion.

The 30' is a skeg boat. And a small one at that. Not at all surprised to hear about the pounding

I believe the 30 " are a far different design then the 31 and the 35. I tried to find the info so I wouldn't not give you wrong Facts, but all i can remember was being told the only similarity was the name. The 30 I believe is a design that has been around for ever, as the 31 where designed in mid 80's by spencer Lincoln . There's a bit of info on Atlantic 's site.
Personaly Not judging or comparing , I've never been on a 30, just FYI.
A 31 -35 Duffy will never really "plane"

Built down or Skeg

This is off the Duffy “Altantic Web site:
http://www.atlanticboat.com/
The Duffy 31 was designed by Spencer Lincoln in 1983. Her hull lines closely follow those of her larger sister the Duffy 35. The Duffy 31 is a built down, semi displacement hull with a fine forefoot and flat after section. She has the tumblehome and sweet sheer shared by all the Duffy's. Her original design as a commercial lobster boat made sea-keeping the top priority in her design. Over the years we have built over fifty Duffy 31's and they can be found lobstering all over the east coast.

I have been searching but I can't find that info on the difference , I'm sure there's an old salt on here that knows. I may have the info in the stack of printed emails from Stacey at genral marine, I will search.

The 30 and 31 are worlds apart. The 30 is super flat aft and is basically on plane as soon as you put it in gear. More like a giant skiff. It was designed I'm told to be a bay boat/inshore lobster it's primary use has been for race boats I'm told. The "voop" (sp?) was a Kevlar Duffy 30. Extremely light weight and fast. Definitely not as seaworthy as the 31 let alone 35. My primary use as in 99.5% of the time is going to be inshore. With all that said she is a great looking boat and her stern is super sexy....

Yes it is a pretty boat. Nice traditional lines. What's the wide open speed ?

With the gasser in it new it hit 41 mph but who knows. They are saying 30knots wot. I think it's going to make a good in between boat. It's not realistic to get a flowers 33 this season soooo I figured this will put me on the water and then when it's time to get out of it I can't get hurt to bad.

On the old ABC website there was a writeup for the 30', just as there are writeups for the 31, 35, 37 etc currently and I wish I could find a cached version of the website that shows the writeup...it said flat out that Spencer Lincoln designed the 30' for racing.
