The 31' Searunners have made ocean passages, & you see them come up for sale
pretty regularly. Though as stated, they are prone to issues with the centerboard
trunk. And I've seen one or two where the loads from the spar were starting to push the trunk out through the bottom of the boat.
Some of that's age, & some is design. So if you get one, have a good survey
They're good for 1-2 folks, but you really have to watch the weight. As, for example, on mine, once I off loaded my library from the aft cabin
to my storage
unit, the ass half of the boat rose 1.5". And that was only 100lbs +/-
Realistically, they all could use transom extensions. As Jim Brown did to his 31' on the main hull
. But even with that they're not great for loads. And IMO, all of the boats could use higher volume amas, for the extra buoyancy. Both for cargo carrying, & because as all 3 hulls on the boats are designed to be sailed with much of their transoms immersed. Often by quite a bit, which is slow.
Not slow in the miles sailed per day kind of thing, but as compared to boats which aren't dragging their asses that much. And it's noticeable in light airs on all Searunners. But even the 31's will tick off miles in a breeze, with gear
As to that Shuttleworth
that you're speaking of, yes, it appeared to be a smokin deal. And Kurt's boats do come up for sale
, but many of them sell by word of mouth, pretty quickly, before any advertising's needed. Though as with anything, sometimes you can entice an owner into selling.
Richard Woods's boats get listed with regularity. Though the vast majority of them are in the UK, which only makes sense. As many/most of them get built there. But the prices are reasonable for cats.
One other option with his boats is to buy hulls & or components from www.BoatsmithFL.com
And I gather that they'd also be happy to build you a finished boat too. Which you can also do with Kurt Hughes's boats, & many others.
Edit: To me DB's being an issue hasn't crossed my mind, after spending a bit of time with Kurt (Hughes). Especially given how hugely strong properly built ones are. As, other than the optionally sacrificial tips, you're not going to break good ones. Plus with the kick up systems & the crash blocks. No worries.
Read Kurts stuff on how they're built, & how strong good ones are & why. Along with the info on kick up systems. Including Shuttleworth's. And get a bunch of design catalogs from various guys.
As for the cost of half a dozen of them, you'll get a decent education on multis. And it won't cost you any more than a nice dinner with a lady friend.
That & when I first took an interest in multis, I read everything which I could find, which was really insightful. And also, folks in the community are happy to help you learn a lot about them.
