Wizard - the ultimate trailable boat

Wizard under sail

The WIZARD is a revolutionary design that offers 5 - 6 berths in 3 cabins, standing headroom, easy trailing, stability AND performance. The lifting hatch combined with the 'pop-bottom' gives standing headroom in the bridgedeck. The latter is raised when sailing. For the first time in a trailable catamaran there is a genuine double bunk.

It is roomy. In its 22' length there are 5 berths in 3 cabins for privacy (3 singles in the hulls and one double on the bridge deck), a separate toilet compartment. Galley and a dinette seating 5. There is standing headroom in the galley using a "pop bottom" in the bridge deck. For an interior drawing see Sango which has a similar layout.

It is fast, the computer predicts speeds of 10 knots under power (with a 15hp outboard) and 16-18 knots under sail (with the racing rig). Practice confirms this, see the youtube video of a Wizard sailing in S California, below.

Yet it is maneuverable and easy to sail single-handed. It has shallow draft and is beachable.

It is legally trailable world-wide behind a family car. One person can assemble and rig it in under an hour ready for launching with no heavy lifting (e.g. the mast is raised using the trailer winch).
Wizard overcomes the trailing problems outlined earlier by using separate launching trollies. The road trailer uses swinging "gallows" to allow the boat to be raised clear of the ground (again using the trailer winch). When in the "up" position the crossbeams hinge and the hulls swing under the central cabin to reduce the width to the 2.5m trailing limit.

"The whole operation - (unfolding and launching the boat including stepping the mast) - had taken 20 minutes of easy work."
"Extremely good maneuverability under power"
"She was close winded, well balanced. I found her an extremely easy boat to sail"
"She's spacious and has the feel of a larger craft"

David Hunter writes: "I finally organized some photos, (see below) these show the boat at 45 to 55 hours build time all is going well. While I'd rather be sailing than boat building I must say its very exciting to see it coming to life before me. Thanks for all your wonderful back up email support, I hope not to ask to many tiresome questions."

You can see a youtube video of Ralph's boat here (15.3 knots fastest speed!)

and another one here (taken using a video camera attached to a kite - brilliant!)

I have drawn removable hull cabins for the Wizard and Sango. A sketch is below.

The cabins are removed for trailing and fit one inside the other on the cockpit. The new cabins give more light and ventilation and increase headroom to 1.5m (5ft). Although designed for the hard chine version they can also be fitted to the original strip plank boat. You can see basic drawings HERE.

I am sure once you have got this far with building your boat this will be enough for you.

Note: If requested hard chine plywood hull plans will be sent as an email of pdf drawings free of charge when you buy full building plans

This has to be one of the best finished amateur built boats I've seen. Well done Ralph Maggio of S California!

After finishing his third race Ralph reported:

"By the time we got to the mark the wind had built to about 13 knots and all six monos (30' and bigger) had passed us and were setting there spinnakers for the next 5 mile downwind leg.

Turn at the mark, unroll the reacher and we are off. We keep it hot, and do a steady 10 knots seeing 12 and 13 in the puffs. Jibe over to lay the leeward mark.

Round and harden up to a very close reach to just lay the next mark about 4 miles ahead. Round that one and head to the finish line. We are first over all with the next boat 20 minutes behind! "

Donald Mckee writes: "I have just lifted out after my seventh season of sailing. It was one of my best because I retired 2 years ago and just dawdled about Skye, Scotland. I was stopped in the street in Portree by the skipper of a 32 mono who asked me how fast I was going when I passed him going across Broadford Bay. He was horrified to hear that I was doing almost ten knots, haha. Also in Skye, a man came up to me and offered to buy Cornalari on the spot!! I am delighted with the Wizard, thank you."
