Advice please about open deck cat designs

[SeaSeeker]

I am searching for DIY plans for an open deck, day sailing cat to be used in protected water with consistent 5/7 knot winds. Want something between 36 and 48 ft. preferably epoxy&ply stitch and glue to be built by a professional yard not experienced with this type of construction. Needs to be suitable for 15 to 25 pax loading from beach for one hour cruise and for sunset booze cruise. Outboard 30/40 hp, rig can be sloop, junk, crab claw. I've looked at the Wharrum designs but don't see any that are just right, no need for below deck cabins, just a small head and galley. Also have seen drawings of a KONKTIKI, repeat KONKTIKI 48 which looks very close but can't find any other info. about it.
Any suggestions, ideas welcome, thanks

Scape, Voyage and others make a day charter version. There is a MaineCat 41 on YW that is licensed for day charter but for less people. A true open bridgedeck is a rarity.

About the best for your purpose's and with the stitch and glue method would be a Tiki.. you don't have to have the cabin area's.. contact Hannake at Wharrams and I'm sure she could knock out a variation for you in no time..
Having owned the 21 and 26 versions I can assure you they sail very well and the schooner rig would be well suited to your needs methinks..

If you are having a professional yard build it, why would you want to use a method that they aren't familiar with?

Consider, checking with tourist areas in the Caribbean. They are pretty common for almost exactly what you suggest. I'm sure you could get ideas or even find a manufacturer.

The 38' Hughes is here; Kurt Hughes Multihull Design - Catamarans and Trimarans for Cruising and Charter
What came to my mind were the Simpson Woodwinds, not quite what you described but the freeboard could be cut down ?

I couldn't imagine a wharram would be the best design when the average wind speed is 5-7K as the OP says.

I would be going for something very light with a large sail area. KHD would be great.

Very good point.

It would probably cost less to build a glas/poly catamaran at a pro shop.

Thanks all, as usual the community responds with much sage advice.

Have a look at the Malcolm Tennant Multihull Design Ltd - Home site. Malcolm designed a number of open bridgedeck cats before he tragically died.

Believe it or not, this open deck catamaran was a home built Shuttleworth design. I'm amazed at the finish quality. No idea how he did it. But I'm willing to take lessons.
