The Sailor Behind the Helm: Kevin Boothby, PhD
Kevin Boothby brings a high-resolution diagnostic mindset to the Gilmer platform. Holding a PhD in Physics from the University of Chicago (1996), he transitioned from a corporate career in risk management to the sea in 2001. His expertise is grounded in his ability to manage the technical and physical forensics of an engineless vessel, famously documenting his 30,000 NM circumnavigation as a study in radical self-reliance. He represents the definitive voice for mariners seeking to master the technical stresses of blue-water handling through the "Small is Safe" philosophy. Source: professional profile archive
The Boat: SV Ruth Avery (Gilmer 31)
The Gilmer 31 is a legendary Thomas Gilmer design, known for its extreme structural integrity and traditional lines. Ruth Avery is a significant 1984 kit version built by C.E. Ryder Corp (Southern Cross 31). Following a forensic refit over 20 years ago, the vessel has undergone a radical transformation, most notably the removal of its auxiliary engine. Key technical features include a 31ft LOD and a heavy-displacement hull, providing the structural integrity required to manage the high-velocity "Northers" of the Atlantic. In 2026, the vessel serves as a world-class laboratory for engineless seamanship. Source: kevinboothbysailing.com

Back to the Bay, Season’s End | Ep. 351
Despite forecasts of moderate southerlies, I spend hours drifting off of Cape Lookout in near calm conditions. But alas the winds fill in, though never as strong as forecast, and send me on my way around Cape Hatteras and on to the Chesapeake Bay. This will be the last passage of the season, as I...
Gulf Stream Carnage | Ep. 350
The winds freshen from the east, kicking up the Gulf Stream. While getting into the head compartment the door flies open and tears off the top hinges. OK, another repair to make. Southerly winds a head of an approaching front blow me into the narrow entrance to Taylor Creek, in Beaufort, NC. Th...
A fair wind! … after only five weeks of waiting | Ep. 349
Waiting for favorable offshore weather can drive you crazy. Even the kinder, gentler northbound run in the spring (as opposed to the southbound run in late fall, invariably a bear) can have you sitting in port for weeks. Of course it's tempting just to sail and hope for the best. In time exp...
Well this is unexpected | Ep. 348
I enter Biscayne Bay via the Cape Florida Channel on the faintest of winds. Then an entire month passes as I shuttle back and forth between Key Biscayne and Dinner Key, all the while looking for a weather window to head offshore for the Chesapeake Bay, or Beaufort ... I'll even take Fernandina...
Finding a Fair Wind to Biscayne | Ep. 347
The first segment from Key West back to Biscayne Bay has you steering ENE, which frequently means that either one is going to slog into the prevailing easterlies, or wait for a southerly slant. Being gaff rigged and engineless, I opt for the latter. But that does mean some waiting, and as the weat...
The Circle Closes on a Zephyr | Ep. 346
One month and one week was the nine-hundred mile loop I sailed from Key West, to Panama City, to Boca Grande, and back. My mini-mid-winter odyssey. It was certainly better from an educational standpoint than laying at anchor in the Keys all winter while waiting for warmer weather to head back nor...
The Charlotte Harbor Tour (between cold fronts) | Ep. 345
Still lots to see of Boca Grande and Charlotte Harbor, but the winter cold fronts are coming through fast and furious. Which means that tourism has to yield to the exigencies of finding safe anchoring ahead of severe weather. SUPPORT HOW TO SAIL OCEANS ON PATREON: HOW TO SAIL OCEANS ON RUMBLE: ...
Baffling Winds, Beautiful Boca Grande | Ep. 344
I finally enter Charlotte Harbor, four days out of Panama City, FL, owing perhaps more to the flooding current than whatever wind there was. But an afternoon sea breeze works up to propel me to the anchorage off of Boca Grande Marina. Boca Grande is certainly scenic, although the nearest Publix ...
Panama City to Boca Grande … almost | Ep. 343
I'm off to a glorious start from Panama City, bound for Boca Grande and Charlotte Harbor, romping down the Gulf with fair northerly winds. But in total defiance of the weather maps, the winds just south of Port St. Joe shift southeast--dead on the nose--so I find myself tacking and barely maki...
Grand Lagoon, Tricky Exit, Southbound | Ep. 342
I find my way ashore to St. Andrews State Park, where I can land the dinghy, dump trash, take on water, and ride my bicycle to the Publix. So that's a win, even though it cost me $4 to get back into the park. Anyway, there's a window to head back south to Fort Meyers, and I'm going ...
The beaches are breathtaking, but the winter is cold | Ep. 341
After provisioning and exploring Watson Bayou, I make my way to the highly recommended Shell Island anchorage. It does not disappoint. However, the weekly frontal passages bring not only brisk northerlies, as they do everywhere in Florida during the winter, but bitter cold with overnight temperat...
The Ghost Coast | Ep. 340
I slowly approach the Gulf Coast. Light winds prevail. Even with the white sandy beaches and tall buildings in sight, I see almost no signs of life other than a few small powerboats. Nothing on AIS. Can't see any sailboat masts. Did some apocalypse just occur? Once inside St. Andrews Bay ...
Passage to Panama City | Ep. 339
I depart the buzzing and booming city of Key West, northbound for Panama City, Florida. After a mild frontal passage, which puts me through the usual sail drills, conditions quickly moderate. Wind and seas diminish over the next few days, making for slow but comfortable sailing. SUPPORT HOW TO SA...
An Excursion to the North | Ep. 338
After a period of active weather, the weather maps are clear for the next week. Fair winds for northbound passaging are indicated, so I decide to push off for Panama City, FL. Besides my visit to Galveston, TX, in 2002, I have yet to cruise the Gulf Coast. SUPPORT HOW TO SAIL OCEANS ON PATREON: ...
The Anchoring Dance | Ep. 337
I arrive in the Florida Keys. Warm waters, sunshine, carefree ... um, no, not carefree, not in the winter. Cold fronts come sweeping across the Keys typically once a week during the winter months. The low islands offer little wind protection, and the holding is not always great. So one has to ke...
To Key West! | Ep. 336
I arrive in Biscayne Bay in the middle of the night (naturally), nearly fourteen days out of Poquoson, Virginia. After re-provisioning and making some repairs, I am promptly off to the Florida Keys. SUPPORT HOW TO SAIL OCEANS ON PATREON: HOW TO SAIL OCEANS ON RUMBLE: HOW TO SAIL OCEANS TEE SH...
Slow Sailing. Nice Sunsets | Ep. 335
Following that screaming gale I spend a week inching along toward Biscayne Bay in little or no wind. Entering into the Bahamas the seas become flat as a lake, and the sunsets are spectacular. Still I wish I was progressing a little faster, especially when the fresh food runs out. SUPPORT HOW TO S...
Dream it, do a lot of work, then live it | Ep. 334
After a screaming gale I get light airs. Not complaining, although the slow progress does get frustrating after a while.

Full Gale | Ep. 333
I am unable to get far enough south to avoid gale conditions ushered in by a passing cold front. No option remains but to reef down and ride it out. SUPPORT HOW TO SAIL OCEANS ON PATREON: HOW TO SAIL OCEANS ON RUMBLE: HOW TO SAIL OCEANS TEE SHIRT: DONATE: WEBSITE: VIDEO SOUNDTRACKS:...
A Race Against Time | Ep. 332
The usual late fall offshore passage scenario. You depart the US east coast on the tail of a cold front, which supplies you with favorable northerly winds. But there's always another front moving through in a few days' time. The typical strategy is to sail south as fast as you can, by w...
Here We Go | Ep. 331
No offshore weather window will be perfect. So long as the forecast calls for mostly fair winds and no severe weather, that's a window. And so it is. Well almost. I have to move south fast in order to avoid a rather strong frontal passage four days out. Other than that, looks like a decent...
Cruising the Corrotoman, looking for Southbound Weather | Ep. 330
Despite the light and fickle winds I work my way up the Corrotoman River to a place called Sandy Point, where I am detained for several days on account of inclement weather. It is October after all.

Yes, but can you sail into Jackson Creek at night? | Ep. 329
A forecasted gale obliges me to put in to Put-in-Creek, on the East River of Mobjack Bay. It is still too early to head south, and October is a great month for cruising the Chesapeake, so the choice is clear. Owing to light winds I don't make Jackson Creek until just after dark. A tricky ent...
