How are these models similar and different? I'm curious of different ride qualities, speeds, weight, hull differences

I can't speak for the cafe or the mistress ride. The ride of the flat deck is awesome. The differences are the length, deck, dash, cuddy, cockpit, and weight. Speed all comes down to the engine package. All three have great things to offer. It comes down to personal preference.

The Flatdeck and Cafe racer are deeper cockpits than the mistress as well.

None of the are known to be speed demons. So if its speed your looking for, forget all three hulls! LOL.. Ride quality will be very good on all three boats. There are a couple really nice flat decks for sale now including Sonic700's boat.

The Mistress and the Cafe are virtually the same bottoms. The Flatdeck is a little stretched. They built 4 Cafe's with Notched transom. They all ride great. Predictable, not fast and they take some horsepower to get moving. Classic that will never go out of style. Some great deals out there on some sweet looking boats. Tougher and tougher to find Cash Buyers on older machines, you figure the newest straight bottom mistress and flatdeck is 30 years old.

I wish there were more on the market right now; maybe come spring some stuff will start to show up..

there is quite a bit on the market right now. they are just being bought up

I've had all three Flatdeck very heavy. Plows thru big water Slow with stock 482's trs Like a tank!
Cafe is smaller & nimbler, good ocean boat The cockpit is deeper. I think sleeker lines. 420's trs
My mistress was a Kevlar boat, light fast with stock power. It had 330's originally trs. I repowered it with more hp. Very fast then
I have had a total of 9 Cigaretts since the late 70's Plus many other makes.

They have been selling for the price of motors, gimbals, drives and tabs. Some Great deals have been had, but we all know the cost of updating....it can get stupid.

What are you looking for?
