The Cape Dory 30 is a genuinely sound Alberg full-keeler with a short, predictable problem list, most of it age rather than design sin. The survey is really an audit of bedding, one aging diesel, and the consumable parts any forty-to-fifty-year-old boat has quietly used up.

Three of the 10 model-specific checks

These are free, and always will be. The kit has all 10 for this model, plus 83 general checks covering the fast screen, every system, the sea trial and the haulout, 17 repair-cost reference lines, and the walk-away list.

Budget rebedding for the bronze ports and deck hardware

Rebedding is near-certain on any un-refit CD30, so check the interior below every port and fitting for water staining, and be glad if a prior owner used butyl or polysulfide rather than silicone, which corrodes the bronze.

Operate every bronze seacock, including the raw-water intakeSafety

The Spartan tapered-plug seacocks are excellent but seize when the grease dries out between haulouts, and a seacock you cannot close, or a rotten wooden backing pad under one, is a sinking risk.

Meter and tap the balsa deck core around every fitting

Water enters at chainplates, stanchion bases, and winch and cleat pads on boats that were never rebedded, so expect localized wet readings there, though end-grain balsa tends to keep the damage contained to the offending fitting.

Straight answers

Is this a substitute for a surveyor?
No, and it does not try to be. A professional survey is what your insurer and your lender will require, and you should buy one. This kit is for the trip before that: deciding which boat is worth paying a surveyor to look at, and walking aboard able to see what is actually in front of you. It also makes you a far better client, because you will know what to ask the surveyor to focus on.
What form does it come in?
A web page built for the job: checkboxes, note lines, and a print layout that comes out clean on paper if you would rather carry it. It works on a phone in a bilge with no signal once the page has loaded. No app, no account.
Are the cost figures reliable?
They are broad US ranges at yard labour rates, and the kit says so on the page. They exist to tell you whether a finding is a $500 problem or a $30,000 problem, which is the decision you are actually making on the dock. Get a local quote for anything you intend to negotiate on.
What if I buy the kit and then buy the book?
The $19 comes off. The kit price is credited automatically against the digital edition of Cape Dory 30 at checkout, so nobody pays twice for the same research.
What if I do not end up buying this model?
Then it did its job. Most of the value in a kit like this is the boats it talks you out of, and the general sections, the sea trial, the haulout and the walk-away list apply to any boat of this era.
