    Best use of budget?

    We've been real happy with our F27 as a family boat (3 kids, started with an F242 and outgrew it), and they hold their value well. If you are considering that route and haven't already, join https://fct.groups.io/g/main and post that you are in BC and looking for a Corsair/Farrier. Boats sometimes change hands thru connections on the forum that were never listed elsewhere. Best wishes for your recovery.

    The likelihood that CL's efforts would change the world's mind about Texans is the same likelihood that all of us working together could change the world's mind about Americans. (We're not all that way! lol). Zero. FWIW, I'm a native and spent all my formative years in Texas, and the loudest and most obnoxious and openly/casually racist person I have ever known well is a white Jewish native of the lower east side of Manhattan. But I know he doesn't represent all New Yorkers. On the other hand, the size of the stick up the ass of every New Englander I've ever met has only been matched by their inflated sense of superiority.

    Tides

    I would say that there are tides and "tides" as commonly understood by sailors, surfers, etc. By definition, the tides are deformations due to gravitational forces, and so are not a function of wind, atmos. pressure, and river flow. Doesn't even have to be water - there are solid earth tides. Sea level tides in open ocean, continental slope, and some part of continental shelves are known to incredible accuracy now, thanks to satellite altimeters like Topex/Poseidon (launched in 1992) and follow on missions combined with tidal modeling. Tides in coastal areas with complex bathymetry are not known nearly so well, unless you are close to a tide gauge. "Tides" as most people experience them, i.e. I want to know when it's coming in or going out, and by how much at a particular spot on the coast, are very much affected by wind, pressure, river flow, and even wave conditions. But oceanographically speaking these are separate effects on sea level. The really long period tides (decades+) are also really small and wouldn't have a noticeable effect on the local tide to the average observer. But there is growing evidence that the "king tides" which are increasingly common are due to the "regular" tidal harmonics combined with sea level rise due to steric effects (warmer water has very slightly more volume) and melting polar ice.

    Vendee Globe 2020

    Yes knowing how they must try to squeeze every bit of speed out it seems reasonable even if of very secondary importance to wind. But listening to race reports, reading Herman's and other posts, etc never heard/saw it mentioned. The data from altimeters that measures the SSH may be up to a few days old depending on position relative to satellite ground track and orbit, but there's numerical ocean models that constantly assimilate this data and update surface current ocean product. I would think these teams with high dollar budgets would be tapping into something like that.

    Vendee Globe 2020

    When plotting courses for these boats, do the navigator(s) take the eddies of the ACC into account? Would seem that 1-2 knot current is a non-factor when the wind is blowing 30-40 knots, but maybe at low wind speeds?

    Vendee Globe 2020

    The resolution of the SAR satellites used to create these ice products (SAR meaning synthetic aperture radar in this case) is about 100 m (50 m pixels). RS2, Sentinel-1, and other SAR sensors are capable of much finer resolutions, but at the cost of such a drastically reduced area coverage that they are no longer practically useful for wide area ice monitoring. SAR is especially vulnerable to what is called speckle noise, when means in practice that to distinguish ice with an acceptable false alarm rate, any potential target (ice in this case) that is smaller than a few pixels across must be filtered out because it is much more likely that it is speckle noise. As a result, these satellites are not currently capable of detecting icebergs smaller than say ~250-500 m in size minimum. It's definitely not going to detect any boat-size or smaller growlers. The no-go lines are likely based on where the large stuff was detected, and climatology/statistics extrapolated from that, but plenty of room for error there. So it should not be especially surprising if small remnant bergs are being detected visually (or by feel, yikes!), as appears to be the case from Varan's post.

    That's a trailer sailer!

    Whoa, having the CG of the mast behind the wheel sounds dicey indeed! Good luck engineering a solution on that one! A common and simple mod for many in the Corsair community (haven't done it myself) that may help you as far as the mast staying centered is as follows. Keep only the rod (or replace it) of the rear support which will continue to serve as an axle. Upon this, thread 3-4 (however many appropriate) lawn mower wheels (the smaller kind 6" diameter or whatever). On the ends, use much larger diameter wheels (10-12" or whatever is typical for the rear wheels of some push mowers). The whole assembly of 5-6 wheels still fits inside the outer poles of the rear support, keeping them captive. Simple, cheap, effective solution to the problem of mast wondering laterally as it is slid forward/aft. On my to-do list even though I don't raise/lower much.

    Cool boat! And as a north Texas native I'm more of a Rangers fan but love that your sporting those vintage 70's Astros colors. What kind of mast supports do you have, and what are you considering? I'm slow as hell at mast raising/lowering on both the Corsairs I have owned (it's a rare event for me, I keep her mast up on a trailer at the marina) but it never took more than a few minutes to move the mast to/from transport/raise. On these boats, the supports are only two: lying the mast on the pulpit, and a removable support that inserts into a bracket on the transom that has a wheel on top. Lower mast onto aft support, walk forward with mast rolling along wheel aft until you reach pulpit to stow. Opposite to raise. It's definitely the brute force part of the operation, but only takes seconds to minutes, depending upon if your spreaders snag. Some guys build there own middle support at the mast step if they are hauling boat 1000's of miles but not necessary for short hauls. Here's a couple of pics (not my boat) that I pulled off the web.

    New Corsair 880

    You should join the Farrier/Corsair Trimaran group on groups.io if you haven't already and seek opinions there as well. There is an established poster on that forum who enjoyed his F27 for many years before deciding to move up to a brand new Corsair 31. He then documented how he spent the next 3+ years correcting Corsair's build mistakes. To this day, he remains quick remind the forum of his disgust at having to do so much of Corsair's quality control for them. That's just one man's story of one boat. And I don't know enough about the Corsair company to say if the issues of a few years ago are the issues of today. This post is not intended to rag on Corsair. I'd sure love to have an 880! I would just say that if getting a boat that is proven ready-to-go from day 1 is high on your priority list, you might want to steer clear of a brand new build. Save a 100 grand and let someone else iron out the kinks. My first "family" boat was a F24 Mark 2 which I got when the kids were 5, 3, and 1, for all the reasons you stated. Five years later and the kids are bigger and so I traded it six months ago for an F27 which needed some love. I have spent most of the last six months fixing her up and making her pretty. F27s that have a long list of needs can be had for near 30K or less. But there is no reason you need to go that route. If you are willing to go to 40-45k, you can buy one from some anal perfectionist who does rigorous maintenance, has done all the modern upgrades, and just replaced the sails a couple of years ago. Mid 30's for something in between. Or look at an F28. Even a turn-key used boat is still going to have a couple of things that need to be done. But good chance of that with brand new as well (from what I hear, never had one myself). Yesterday I was in moderate wind with my buddy screaming across Biscayne Bay on my F27 at 15 knots under main and genoa. And my sailing skills are average, at best! And yet this is a safe family boat that makes a great platform for day sail exploring, picnicking, snorkeling, etc. You'll love it.

    American Dumbass

    This is an Austin tradition. When I was a student there in the 80's, all you heard was "yea should have been here in the 70's when Willie held court at the Armadillo World Headquarters blah blah blah before it got so damn crowded". A great song from my period there by a band called Ed Hall was "Things were so much better before you were here". Went there for the first time in years with my family last year, and damn it is crowded. Still, if it just had salt water. I had to laugh reading this. Everyone in my family is a native Texan. My sister and her husband (also a Texan) moved to a ski town in NM a couple of decades ago. Since covid, no one has seen each other in person, so we have these big family Zoom calls with mom and dad, other siblings, kids, etc, and not a single call goes by without them bitching at us about "you damned Texans need to ..." based on whatever asshole behavior they just witnessed from a Texan in their beloved little ski town. WTF sis on a lot of different levels there. Texas is certainly full of assholes. So is Florida (duh) and yes even Hawaii, the two places I have lived in the last 3 decades since leaving my homeland. Just different species of asshole. Texas also has a shit-ton of exceptionally cool people. Cruisin' Loser sure sounds like one I'd like to have a Shiner Bock with.

    How long did it take to find/buy your boat?

    My first boat was a Phil Bolger design I built myself. Super simple, should take me about 3 months. 5 years later, I was sailing. But if you are looking to buy used, you're already ahead of me here. Moved to Hawaii. My 2nd was a Hobie 16. My girlfriend (now my wife) and I looked at it and bought it. Total "search" was maybe a week? Fast forward a few years, back in South Florida. Knew I could never give up the speed and fun of a multihull, but have 3 kids now. Did some research and decided a Corsair 24 was the way to go. Looked at a Mark I here in Miami that was in crap condition and passed. Looked at Mark 2 up in Vero and bought it the next week. Maybe six weeks had passed once the idea of a Corsair entered my head. This spring, cruising in the Keys with family (kids much bigger now) decided we needed a bigger boat. Talked to a friend a few days later, who knew and much older guy with an F-27 that wanted to downsize. Within 10 days we had traded boats. I've spent most weekends last 4 months replacing rigging, doing lots of little jobs, making her pretty again. Ready for fun now. Moral of the story: it helps a lot to know exactly what you want, and live in a place with lots of examples of what you want.

    Single mission or multiple mission boats

    Ha, you explained things for me before I greatly simplified my post. I was just reading about F82-R on the Farrier site. About the same length as the F27, and about half the weight! There's your single vs multi-mission in a nutshell.
