    Rolex Middle Sea 2020

    O55 light, 2 MOD 70s, Paradox/Shockwave, a Multi50 and an Ultimo. O55 rating seems optimistic, Paradox’s rating seems favorable, MOD 70 match race should be fun, and the Ultime doesn’t even have a rating. with not much else going on, should be moderately interesting https://www.rolexmiddlesearace.com/entrants/?year=2020&race=5e25756baec57e0000a2a44c&category=5e25756baec57e0000a2a438

    Did something break on Shockwave?

    Race to Alaska best boat

    Does anyone have pictures of the bicycle pedals setup on Mama Tried?

    Assy vs Sym

    Is there a chance that a bowsprit + asymmetric spin + jib might outperform a poled out symmetrical spin downwind? A displacement 40’ cruiser/racer (Bene First40). 10-15kt TWS.

    Rolex Middle Sea 2020

    Just via modeling it in software? Or actually trying things on the water? Is there a VPP so good that it can model waves, foil and sail drag/lift trade off, etc accurately? Or are those just paper gains so far?

    Assy vs Sym

    Okay, what about same size a) assy+jib vs b) symmetrical? VMG downhill? Is there an established truth? Big$ ocean racers seem to use a), but they are reaching, short handed, and not in displacement mode (even without foils).

    Assy vs Sym

    As large as it gets in both cases. Or, put another way, what relative kite sizes might result in a similar PHRF rating (I know, cue rating committee jokes).
  8. You’re right, was looking at the nearly identical pic:
  9. You’ve got to give them points for the tiller, no wheel on a 57’!

    Last of the Gunboat 55’s

    Hadn’t realized they were so narrow - 25’ beam vs say 28’ in A55/57 that is a similar size and configuration. And 2 of those flipped. Could it have contributed to Rainmaker’s crew feeling unsafe and abandoning an apparently intact vessel?

    Last of the Gunboat 55’s

    Vb 55 #9 STARR is on YW for $1.65m offered. Surprised about it being fitted with centerboards, but looks pretty high on its lines in the water and not stearn-heavy.

    Boat 4 sale; not mine

    Why do you think that is? because you can push them more on a mono, given no risk of capsize?

    Boat 4 sale; not mine

    Well, yes apart from the N2E and Transpac with Mighty Merloe, are there others? Fastnet and C600 had the same 2-3 MOD 70s fighting it out among themselves but no one else close on elapsed. Ultimes were built for trans-oceanic races. Were they ever in a race with MOD70s or ORMAs (not a rhetorical question, I really want to know)? Think their biggest race was 2018 RdR, where 2 finished close, 2 finished weeks apart, and 2 "retired". There is probably a way to put together an exciting race circuit with assorted one-time 'round the world record beaters, just doesn't look like anyone figured that out yet.

    Mighty Merloe beating MOD70s is an interesting subject. I suspect that it’s down to the crew and local knowledge, but would love to hear more. Did it sell? Are there other races where MOD70s, ORMA 60s and Ultimes race together? I guess it would be informative to ask Tritium’s current owner why he’s selling and wants to do the next Transpac in a sled.

    But you won’t... not boat-on-boat. New ones will kills the old ones. If absolute SOG per $ we’re the target I agree with you. But the target is SOG relative to others. The only honest race is fixed $ budget. Here’s $1m, first around the globe in one piece wins. And even there the resale value needs to be managed. A $1m budget where you’re okay to lose it all is more than $1m budget where you think you can sell what’s left for $500k.

    Three general racing types: 1. One design or close (class 40, multi 50). The best resale. Think J-boats, Lasers, Figaros. 2. Cruiser-racer PHRF racers. Dual use makes resale okay due to cruisability. 3. Development, “no holds barred” racing. America’s cup, etc. The highest outlay for the least resale. If you’re not competitive anymore against other cutting edge boats utility drops to zero, or negative, considering the effort and costs.

    Where is the limit on an f27/f28?

    If burying the lee ama is no big deal then you don’t have the critical information where it actually matters. Once the lee ama is submerged you’re in the negative stability zone (not as steeply negative as flying the main hull, but negative) — more heeling momentum brings less righting momentum. I think the right cruising tri design needs the amas sized so that burying one is the “oh shit” moment, not the “let’s see if I can ride this one out” moment.

    Over the horizon

    Curious as to what the energy loss rate is for: a) hand-steering vs b) rowing machine to alternator to battery to auto-pilot chain. Looks like 80% loss? Like 40% at each stage? Soma and Dave — what are your real-time strategies for Gonzalo? Euro model says its nuthin’ (because it thinks it will hit land in Venezuela).

    Over the horizon

    I was thinking it may serve an extra motivator for exercise... can also attach a rowing machine to it.

    Over the horizon

    I always thought Tesla’s power wall was a way to eventually recycle old car batteries... Dave — you once said you have a stationary bike for cardio on board. Any thoughts of attaching it to a generator? Or it’s simply not enough KWHs for the hassle?

    Over the horizon

    Hey soma, any reason you chose AGM over Li-po? And have you estimated the weight cost of A/C?

    Is this what we have come to?

    Didn’t see many complaints about the same thing on Rapido 50 renderings:

    AC45F Lux for sale

    How many athletic men in helmets does it need to launch and sail it? I’m sure it’s a nice boat, carbon fiber and all. But possibly an example of how the clearing price for old race multihulls might actually be negative. Which is a shame.

    Used cat market

    Wiley Sharp of Denison puts out pretty useful quarterly reports on brokered cat sales. The latest is here: Q2’2019 I put the data from Q1’2017 to Q2’2019 into my supercomputer and made some charts... Only used cats 49’ LWL and longer (cuts out a lot of 47’-48’ FPs, Leopards, and Lagoons since this is SAILING Anarchy). Also removed 3 sales that were on the market more than 5 years. This left 116 sales over 10 quarters. Chart 1: Depreciation stops at 20 years and at $200k. The two yellow dots are both Privilege 585s both sold in Jan’19, I suspect there is something dodgy about those sales, both in France. Otherwise pretty clean data. Chart 2: Average years on the market since listing. In practice probably longer, because of de-listening and re-listing. At over one year this is the true deadweight cost of selling a cat. Brokers do work for their commissions (some more than others). The difference between the offer price and the listing price is not a real cost — listing price is just a guess and a marketing signal, (accepted) offer price is the true market price. But cats spending a year until the clearing price is found, accumulating depreciation, dock fees and maintenance, is the real economic loss. So what Wiley Sharp is doing in disseminating these data is a real service to buyers and sellers, since more information = faster decisions. Chart 3: Sales have picked up in 2019 from 10 per quarter to 15-20. This could also just be more sales getting input into YW’s sales database. Chart 4: Average selling price. This picked up in Q1’2019 on the sales of 3 Outremer 5Xs (yum!), and 3 somewhat dodgy sales of Lagoon 620s (Venezuela, Turkey, and Spain — if you need to get your money out of Venezuela pay $1.5m for a Lagoon, but I don’t know). Q2’2019 is the lowest price quarter. Interestingly 55’ Wormwood Avalon appears to have sold in May this year for almost $300k. Another one that I quite liked was Pinta 52’ tri, sold in March for $225k after almost 3 years on the market. I almost went to see it, but “granite countertops” stopped me.
