What readers who applied it say

★★★★★
I've bought and sold six boats since the '80s and thought I knew what I was looking at. The hammer test caught soft transom wood on a boat I was ten minutes from buying. Nobody at the dock said a word about it.

The bilge on that pontoon was spotless, which should've told me something right there. Chapter 5 explained exactly why a too-clean bilge is the tell, not the comfort. Saved me a trip to a boatyard I didn't need.

I'm retired, on a fixed income, and I'm not paying six figures for fiberglass that'll blister in ten years. This showed me where the honest old steel hulls still sit, cheap, at yards nobody's looking at anymore.

Rennie Boat Value

I spent close to thirty years around boatyards, from the Chesapeake to the Great Lakes, first as a rigger's helper, later doing pre-purchase walk-throughs for buyers who didn't want to pay a full survey on a boat that might not be worth it. I watched the same men, mostly retired, mostly careful with their money, get talked into rotten hulls by a good paint job. I started writing down the exact checks I used on the dock, the ones that take seconds, not the ones that need a moisture meter and a certificate. My own boat is a 1974 steel-hulled cruiser I bought for less than a used pickup truck. It still runs.

Why I Wrote This Down

For years I did informal walk-throughs for guys about to buy a used boat, most of them retired, most of them careful with their money and tired of being talked at by a dealer or a slick seller. I kept seeing the same tricks work: a fresh coat of gelcoat over a soft transom, a bilge scrubbed cleaner than the rest of the boat ever was, hardware that didn't match because half of it got replaced after a leak nobody disclosed. I started writing down the exact checks I used, in the order I used them, so a buyer could do them himself in the time it takes to walk the dock. This isn't a substitute for a proper survey once you're serious about a boat. It's what tells you which boats are even worth that phone call.

Frequently asked questions

I've been around boats my whole life. Why would I need a book to tell me how to look at a hull?+
You probably already know more than most buyers. This isn't a beginner's guide to boats, it's a condensed set of the exact ten-second checks a surveyor uses so you can catch a hidden problem the same afternoon you see the boat, before you pay someone else to confirm what you already suspected.
Isn't this what I'm paying a marine surveyor for?+
A survey is still worth it once you're serious about a boat. This is what you use before that, on the dock, to decide which boats are even worth paying for a survey on. Most buyers waste survey money on boats that fail in the first ten seconds anyway.
What if my boat isn't fiberglass?+
Chapters cover steel, wood, and older layups directly, including where the good bones are hiding under ugly upholstery from the 1970s. The rot and corrosion signs are different by material, and the book walks through each one separately.
I'm on a fixed income. Is this really worth the money?+
That's exactly who this was written for. One avoided rotten-hull purchase or one skipped boatyard bill covers the cost of the whole system many times over. Nothing here pushes you toward a new boat or financing.
I already own my boat. Is this only for buying?+
Volume II is built for the boat you already have, tracing leaks, fixing common failures yourself, and keeping the trailer from stranding you. Most owners use both books together.
How is this different from other used-boat guides?+
Most guides are written by people selling something else, a course, a survey service, a dealership relationship. This comes from years of hands-on dock walk-throughs, and it stays focused on what your own hands and eyes can find in ten seconds, nothing more.
