What readers who applied it say

★★★★★
I've run spreadsheets my whole career and I still almost bought a boat with a soft transom because it 'showed well.' The dockside checklist caught it in eleven minutes. Walked away, saved myself what would've been a $22,000 mistake.

★★★★★
I'm not a mechanic and never claimed to be. The hull number section alone told me the boat I was about to sign for had a rebuilt title the broker never mentioned. I walked off the dock without a word.

Bought my Volume II copy after almost signing on a 'turnkey' cat. The rigging cost breakdown alone showed me $9,400 in deferred maintenance the listing never mentioned. Best $47 I've spent this year.

Marcus Kellerman

I spent eleven years brokering and surveying used cruising sailboats out of three East Coast marinas before I stopped taking new clients. I watched retired engineers, disciplined savers, careful men who'd never overpaid for anything in their lives, sign for boats they hadn't really looked at. I started writing down the exact sequence I used myself — the same twenty minutes, the same seven checks, the same questions that make a broker go quiet. I tested it across more than 140 documented boat inspections before I ever wrote a word. This isn't theory. It's the walkthrough I wish someone had handed me before my first boat.

Why I Wrote This Down

For over a decade I watched capable, careful men do more diligence buying a used car than a $90,000 boat — not from carelessness, but because nobody ever gave them a real method, just a survey and a handshake. I wrote this because I got tired of hearing about the 'quiet sale' eighteen months later, the boat that went back on the market at a loss nobody wanted to discuss at the yacht club bar. Every checklist here came from a real boat, a real dock, and usually a real mistake I watched someone almost make. I organized it so you could run it yourself, in twenty minutes, before a single dollar changes hands. That's the whole purpose. Nothing more. Marcus Kellerman

Frequently asked questions

I've already read the forums and watched hours of boat-buying content. What's actually new here?+
Forums give you opinions. This gives you a sequence — the exact 20-minute order of operations, on the actual dock, that catches what scattered advice misses because it's never organized into one repeatable walkthrough you run yourself, every time, before a surveyor ever gets involved.
Won't a marine surveyor catch everything anyway?+
A surveyor works after you've already fallen for the boat and after you've already paid for the survey — often $500-1,200 non-refundable. This system tells you which boats are even worth paying for a survey on, so you stop wasting surveys on boats you should have walked away from at the dock.
I'm not mechanically inclined. Will I actually be able to use this?+
Yes. Every check in the walkthrough is designed for someone with a checklist and two hands, not a wrench and a torque spec. No tools required, no engine teardown — just where to look, what to press, and what questions to ask before you write anything down.
Why not just buy new or 'turnkey' and skip all this?+
Chapter 1 of Volume I is built entirely around this question. The turnkey label is a marketing term, not a mechanical condition — and the premium you pay for it rarely buys you the certainty you think it does.
What's actually different between Volume I and Volume II?+
Volume I is the physical walkthrough — hull, rig, engine, listing language. Volume II is what happens after: what the boat will actually cost you in year one, the 18-month rule sellers don't advertise, and how to price a rig, an engine, and a hidden osmosis problem before you sign.
Is Volume III necessary if I only want a coastal cruiser?+
Especially then. Volume III shows you the exact ratios — capsize screening, comfort ratio, ballast ratio — that reveal when a boat marketed as 'bluewater capable' is actually a coastal design with an ambitious listing. It's ten minutes of math that can save you from a genuinely dangerous mismatch.
