Paste the listing. We check it against the Loop's hard limits and whatever we hold on that model, and we tag every claim with how well it's verified, including the ones we can't answer.
| Air draft | The one clearance you cannot route around is 19'6".

| Water draft | Most listings don't give a loaded figure. Under 5'0" is the preference; AGLCA prefers under 3'0" plus local knowledge for the inside New Jersey route, and sends everyone else outside. Ask for the design figure and the loaded figure. The delta is a function of hull form, not a constant, and nobody knows it until someone measures. | ASK |
| Range | Depends on tankage and the speed she's actually run at. The number to beat is Alton to Paducah, about 250 mi, the longest published run with no fuel stop. | ASK |
| Length | Inside every practical limit, and inside a 50′ personal ceiling. Length is rarely the thing that stops a boat. It is on the list because slip and haul-out billing use overall length, not hull length. | CLEARS |
Nobody has called a yard. It's the oldest open gap in our notes on this hull family, and we aren't going to invent one from a brochure: a number nobody measured can't fail your boat, and that beats handing you a figure that only sounds like an answer.
Live from the shared model layer. These are the same rows a dossier renders, with the tiers and sources they carry right now.
On a 1999 390, the owner found the bustle's foam had been removed years earlier. Both mounting seams had failed, the drain plug had failed, and both trim-tab wells had cracked at the edges, and the platform deck was soft at purchase. The fix was three large deck hatches, recoring, and heavy glass work over the seams, the drain and the tab wells, about $30,000 in all, with no water getting in since.

On the 350 and 390 the swim platform is an EXTENSION OF THE HULL. It displaces water and contributes buoyancy. So a platform full of water is not just weight far aft, it is lost buoyancy at the stern, which is why it moves draft and trim more than you would expect. The originals were foam-filled with no inspection access; water leaks in at the joint under the rub rail and saturates the foam. The foam slowed complete flooding but never kept them dry. Most have since been modified with access hatches, drains, or standalone bilge pumps. Source: a Mainship 34 MK1 owner who operates a 390, Trawler Forum, 2026-07-23
An original sealed platform is a latent water-saturation risk: weight, trim, and eventually structure. A retrofitted one has been addressed. A listing will never mention this and a survey has no particular reason to look. Source: a Mainship 34 owner who operates a 390, Trawler Forum, 2026-07-23

The gates above are the Loop's. Yours sit beside them: budget, layout, route ceiling, 40 criteria you tune once. Every boat you add is scored against your own list.
When the ask moves, log it. Every boat keeps a dated price history with the change computed, so a real drop is visible the day it happens, and a quiet raise is too.
Paste every listing you find. The boat keeps each source on its record, so a syndicated copy or a relist lands on the boat you already hold instead of looking like a new find, and where two listings disagree you can see it.
You still need a survey. We just keep you from wasting one on a boat that was never going to fit.
