Wharram Builders and Friends

A Photo & Discussion Forum for Wharram Design Enthusiasts

Hi I'm JL, I'm new to the site.

It's an honor to have the chance write on this forum. :-)

I'm about to build a Wharram.

What type and configuration you suggest for maximum speed performance?

Tiki 30? Tiki 38? Tiki 46? And what sails and rig type?

I would like to build a superfast ocean/coastal cruiser. I don't care much about comfort.

Thank you in advance for the wise answers ;-)

Thank you all for the answers :)  ...so it's seems to be Tiki 30 the fastest Wharram(stock rig).

How can I reduce overall weight during construction?  Any tip? Suggestion?

I am afraid, most of the weight solong has to carry, comes from my equipment:

  • 3 batteries
  • 2 anchors with chain
  • outboard engine with fuel tank
  • portapotty, water
  • sails for exchange ....


Just a couple of weight-saving ideas during construction:

- Alu mast instead of wood

- Use lightweight marine ply 

- Stick to plans and don't overbuild internal structures

Supply your "needs" and reduce your "wants" when it comes to putting stuff onto your boat. 

Having said all that, we didn't do any long-term voyaging on our Tiki 30, so we weren't tempted to load it up with stuff and the boat sailed quite well. Any poor sailing characteristics noted were usually (and appropriately) ascribed to my inferior seamanship.  Keep the weight amidships and off the ends and the Tiki 30 is a lot of fun to sail. Oh, and keep in mind the Tiki 30 (in my experience) tends to be 'ass-heavy' which helps keep the bows up.

A little off topic but, if you were to sail a Tiki 30 alone or maybe as a couple across the Atlantic (or any other ocean), would the load carrying be a problem? I know you can load it up with "stuff" and "toys", but I mean water, food, fuel, sail, etc..

I have experience sailing the Tiki 30 but no experience with fitting out for an ocean crossing. I would defer to others to comment on the boat's payload limits for voyaging. The Fercots crossed the Atlantic in their Tiki 30 and seemed to have no problems with payload.

In addition, JWD states the Tiki 30 can go anywhere, but it's not luxurious. It is camping on a boat.

Look forward to seeing how you progress with your plans!

Check my youtube clips, then you know:

It is a stretched Tiki of 33 foot. We did many times 14+ knots. But it depends the seaconditions re. waves. Tiki 30's are capable to make passages very well.

WD is sold now to a enthusiastic young sailor, I wish him fair winds! The "old" man does retreat himself to the Philippines. But who knows, may be I'll put up a new boatproject in due time.  For the time beeing I strain my motorbike and my cameras.  Cheers Wave

Thank you again for the replies. Every opinion is precious ;)

Hello Jean-Luc

A big boat has a higher potential of speed but she is more difficult to handle and is very very more expensive.

I enjoyed very much my previous Tiki30 with her Swing Wing rig very easy to handle. The canoe shape of the bottom hull accept to be overloaded, but not too much to keep a minimum of clearance under the bridge deck.

Even if you don't care much about comfort, if you want to sail offfshore it's  important to build a light pod. If not you'll be wet and cold quicly and it's not good for your security. In the Pacific the crew aboard their high sea catamarans lived not in the hulls but on the central deck under a shelter as a pod.

Good luck

I know this is a bit of an old thread, but thought I'd toss out an idea.

Early on when I was figuring out which Wharram to build for my situation, which change for the better and I'm  building a Narai Mk IV now.

But I talked with Hanneke about stretching the Tanenui 2'-6" midship, and raising the deck to height bulwarks and the cabin 2", she said it wouldn't be a problem to do so. 

The Tanenui is one the Slimline designs mentioned above. It won't have standing headroom, but would have about 5'-6" headroom built as such.

I don't know how fast she would be but I would think she would get up and go pretty good.

Anyway, just food for thought.

Cheers, Allen

As I recall, Wharram narrowed the beam to hull length on the Pahi 52, and the tama moana : moar faster! Of course, just like with a car, it helps to tighten the "nut behind the wheel." /:)

Then don't choose a Wharram

I've got an old hobie 18 it's quite fast and very uncomfortable and you can have it for a song
