As a “wish I were sailing” viewer, my compliments on another great Q&A. If my 4 years of engineering school had that much humor combined with such practical knowledge, I might have stayed awake the entire time. But had to laugh at Adam using his engineering scale as a straight edge. In my high school drafting classes that would have earned you a slap upside the head. And your using a permanent marker on the scale edge would given the teacher heart failure. You both are a joy to watch....safe travels. Go for 20 minutes!!!

Finally some sailors who got the reefing rigging right! Love how you patiently explain everything. The halyard to the back so that you only need to attach the ring near the mast and the other can stay behind the steering wheel is very important. I'd suggest you'd rig your 3rd reefline all the way to the back as well. Once you need it, it'll likely be windy or rough seas, you wouldn't want to have to go playing with lines near the mast then. Likewise, you can fit a downhauler in the third reef ring to help get it down in strong winds or even lead it back to allow for an emergency reef fit.

I had an idea where you could do the equivalent of a charter, but with a patron, and instead of paying in cash, they could bring equipment/hardware/whatever for a boat upgrade that you want to do but is cost prohibitive, and then be an extra set of hands to help do the project, while living aboard for a week or two. I can't speak for anyone else, but I think that would be a fantastic vacation. Spend a couple weeks on your boat with you, adding a new thing that I brought along as luggage to pay my way.

Love your channel, you two are cute as puppies! (keep in mind I'm purt near 60).

We ourselves are in the 'Putting Her Townhouse and My Land Up For Sale Phase' concurrent with the 'Boat Shopping Phase' deciding on our BWLASV (Blue Water Live Aboard Sailing Vessel). We hope to see ya'll out there one day! Keep up the good work and... "To the wind that blows, the Ship that goes, and the Bonny Lass that loves a sailor!" PS. (forgive me if you know this, some may not...) Running a sail under the hull like a band-aid to seal a hull breach is called "fothering". This method was used to help refloat HMS Endeavour in the 1700's when she went aground on your Great Barrier Reef. =/|)=

Something that made 'reefing theory' make more sense for me, was the thought that most cruising (displacement) sailboats have a 'design' hull speed and that that speed limit is pretty well fixed. The amount of power we need to move the boat is also relatively fixed. It's the amount of power available from the wind that varies wildly. When adding or reducing sail area (by reefing down or adding say a spinnaker) or by tweaking and trimming the sail shape we are just trying to catch, gleen, or get, just 'the right amount' of power from the wind to move at the boat's efficient hull speed.

Very cool video, highly informative for less experienced yachties. You mentioned that you wouldn't mind runners as well as your cowcatcher, if it ain't broke don't fix it, runners can be very dangerous for your rig, less so on a cruising boat because the likelihood of an accidental gybe is far less than when racing, if your boom hits a runner in an accidental gybe say goodbye to the rig, it will snap the mast quick chop, as happened on a 48' racing boat a few months back, limped into port with the top half of a carbon fibre spar and all the rod rigging on deck, two destroyed carbon racing sails and the spar, that's a few 100 K right there. I'm a huge fan of a Solent rig, all the benefits of a cutter without the need for a cowcatcher or runners because both forestay and inner stay go to the masthead. Great rig setup IMO. When we race, either the 48' or the 64' we have a dedicated guy on each runner with dedicated self tailers to mitigate the risks involved with runners, trust me losing the rig at over 20 knots boat speed is F$#@ing scary. Fair winds and safe sailing

More crew means more help, if someone is willing to fly to your location is obviously ready to adapt to living aboard and dealing with issues as they arise, anyone considering crewing aboard a sailboat should watch some of the SV boats that seek rough water to push the limits of the boat and crew, this will give you an idea of what a rough passage can look like. There are also many crew websites like crew finder etc, with experienced sailors.
