48″ Day charter project

6 Comments

Hi! I’m starting the build of a kurt hughes design day charter cat to be completed spring 2022 in southwest florida. it will be a cylinder molded wood composite build. I’d like to communicate with anyone else who is currently building, or has built a similar boat. i’m a professional boat builder, having built and worked on several of kurts designs.

couple of questions:

  1. anybody have a suitable dagger board mold? or want to use mine when i’m done with it?
  2. any good leads for sourcing rudder shafting?
  3. if anyone needs uni or triax i have found somebody with a couple tons nearby (sarasota area). vectrix and very reasonably priced. let me know in the comments and i’ll post info.

10m power cat update

Leave a comment

At the end of 2018 I posted a power cat hull build. Upon completion of the two hulls, they were picked up by the owners and taken home to Maine to build the crossbeams and cockpit, as well as fit engines, electrical, etc. I’m happy to report that the resulting boat looks spectacular, and the owner/builders say that the shakedown cruise went well, with a smooth dry 20 knots. stock props.

Explaining the Sarabi Anchor System

Leave a comment

Barry showed this to us several years ago. It keeps the down load off of the bow tube, and snugs the anchor back into or near the main beam.  A big roller lives at the end of the bridle, which the anchor line and chain run through.

The live picture is of the Sarabi installation. They used it for years crossing the Pacific. Salty Cat, a KHSD 45 has the same system.

Building power cat hulls

9 Comments

I took on the job of building a set of hulls for Kurts 28’ power cat design which we stretched to 31’ by adding about 2.5 inches to every station. We upped the stringer size by 30% and glassed with 8oz rather than 6oz but otherwise stuck with the plan and laminate schedule. We used multiple layers of 8 and 10oz to make up biax tapes, i find it makes for easier fairing and allows for tapering the buildup. We did a half-way-to-yacht quality fairing job, primed with 545 and installed cleats, hatches, fuel tanks, and fuel fills. There will be lightweight 25 hp engines mounted on rear transoms. We finished both hulls and shipped to the owner in maine, who is going to build the cross arms and center cockpit over the winter. I really can’t recommend committing to building a boat over the summer in sarasota, florida in a non-airconditioned space, but, in the spirit of running a marathon, and other ridiculously painful ways to enjoy yourself, we did it.  Total build time, including purchasing, hardware, and mounting on a trailer for shipment, was in the neighborhood of a thousand hours. LOTS of pictures after the break-
