Server outage and spam

Submitted by administrator on

We were offline for a few hours today. The site was being heavily hammered by spammers of various types, causing the load on the server to skyrocket, and our hosting provider temporarily suspended service in self-defence.

Most of the site is up and running again. Comments and the built-in search tool are, unfortunately, unavailable for the time being until we find a better way to block the spammers.

Crossbeams, little by little

Submitted by Matthew on

Trimarans are finicky to build. There really aren't too many ways to simplify the highly loaded crossbeam structure, particularly when (as in our case) it has to be able to fold for trailering.

Our Starwind 860's aft crossbeams are now sitting partially assembled in the garage. The webs, the strut blocks and the centre blocks are in place, and it is now time to start closing them up.

More S860 crossbeams: Centre bearing blocks

Submitted by Matthew on

The Starwind 860 trimaran's crossbeams are joined on the boat's centreline by a massive hinge pin. This mechanism ensures that the two outriggers fold in sync. The peak load on the centre bearing could be up to 41 kN (about four tons) port-starboard or 11 kN up-down, and the structures around it need to reflect that.
