Catamaran plans, who have I forgotten ?

Turrismo?

 

second number is a running total

I used about 320 gallons epoxy with a falldown rate to wetbagging of about 25 percent. I expect about 240 gallons went into the boat, give or take. The wet bagging is horribly wasteful. My resin ratios were good, but I never had time to skimp on resin in the wetout. Panel infusion would be the only way I'd go in the future.

The epoxy was Silvertip, a non-blushing, low outgas formulation, top of the line stuff, although I'd probably switch to the A brand do it over.

So, I used 2880#/440 or about 6.5x the $2500 you cited. So, your cost was $16,250, or more like $10k US. So you maybe could save $25k on epoxy, but you'd need to infuse the panels or pay help to cutdown on all the wastage.

 

Ya, that was the closest I could find.

This one was listed some time ago but could only find this image.

Listed as a 10 (meter I assume) Turrismo MK3

 

I ran into a few snags as well. Freight was becoming brutal toward the end. My rubrails were like $600 to get shipped. I overpaid for underdesigned hardtop work that turned out nice, but had no drawings.

The bad thing about all the cost is the boat also came in a bit heavier than I wanted. Used mat backed tapes, for example; drove weight and cost, maybe #300 pounds..

 

That boat is really gorgeous. I see some Turrismo 9s as well.

 

It looks from the photos that the engine is mounted forward ?

If you wanted a racer or overnighter it might be ok. I just can't tell much from the pics. Anyway they will either get back or not.

 

I had a look at his sight on the wayback machine. Tourismo is the closest thing listed but that boat seems to lack cabins. The T9 lacks sugar scoops so that's probably the reason for the length.

Or maybe wildfire with scoops

The Tardis 295 power cat , 29'6" , looks like it has scoops , could it be a power cat ?

 

Anything is possible but it looks to me like that boat has it's outboard mounted amidships like the sail boats, and it has part of a rig with it. Boats with large motors mounted aft tend to have fatter sterns.

Also it's hard to tell from the photos but it looks like the bridgedeck roof does not attach to the hull centerline. It LOKKS like it attaches to the deck inboard of the hulls.

Of course this is speculation but it looks like someone got plans for one of the open decks and radically modified it, different beams, scoops, hard deck with cabin. His hulls follow a certain style so hard to say if it started as a Tourismo, GBE or Wildfire. Some GBEs were built double diagonal (not good), or it could be strip or foam.

Hopefully the owner will get back. Wildfire has about 500kg load, I'd imagine Tourismo would be a fair bit more.

Anyway we'll see.

If a Chamberlin Parallax 9 came up for that money in any condition I'd be all over it...but I'd have competition I am sure...

 

Some designers are able to achieve lines that are deceiving with regard to interior space. People are always surprised when they see the cabin of my Skip Johnson Tri.

From the outside it just looks like a slippery aero wedge without really giving away the amount of usable and function space inside.

The Tennant boat might be better than you think, even though looking at things like the diameter of the wheels and size of the car in front of it make it look a bit small in scale.

Based on where the front axle of the trailer lands along the length of the hull, it looks like the motor pod is positioned just behind the dagger boards.

It has a pretty modern look for its age, which is why I suggested and other have also that it maybe modified, perhaps with the cabin being added since the underside of the deck appears to be fresh without any finish?

Hopefully the seller is responsive and you can get the story on it. It’s a good looking boat, and those transom scoops have some great shapes to them. Hard to tell, but there are a few things you can see either side of the cabin against the bulkhead that I thought at first might be the rudders, but now I’m wondering if the are an anchor spot for a drop in hard bimini similar to what the MK3 has which would be cool. I’m a big fan of shade!

BTW, I did find a little bit of interior footage of that MK3, which does look quite a bit roomier than it appears from the outside.

Unless MT did a custom design for them it's almost certainly modified. The std T9 and Wildfire, and GBE for that matter have cabins that interrupt the top line of the boat. I speculate someone got a set of plans built hulls without cabins added a hard bridgedeck and pod cabin. So the interior may be 3' wide or 4' wide, and stooping headroom. Probably more than 4'6" but not 6'. And for some reason they kept the outboard position...left it in the cabin :/

The T9 had fatter hulls so can carry some load, maybe 500-700 kg as I recall, but the others were never load carriers, racers with weekend accommodation. There is too much slope aft for those scoops to have just been tacked on. They would have had to cut the transoms IMO if it was a T9. Maybe not for the shorter boats.

If they started with a donor they did a lot of mods. Cut off cabin and deck that, add scoops, build bridgedeck and cabin. When does it become chasing your tail...

Anyway we shall see. If it's double diagonal I'm out. I've seen how bad a DD GBE can get and it's ugly...really ugly..

 

From the window line it looks like the the heavily modified one done in NZ years ago was sold on trade me named alien from memory had little green blowup alien on it, carbon table etc it was quite the art work. I'll have a foto file of it somewhere but not enough life left to find it. Sorry some of the North Island guys on here may remember it.

 

I finally found some photos of a Tennant Turissmo 9 out of the water and taken from similar angles that aren’t that great, but you can see that it has the same bilge shape, bows, and similar enough scoops.

Searched using the term Alien along with other key words, but no proof of it exists

And I made the mistake of searching Alien Cat.. yikes!

 

Thank you for that. If that is the case any information on it would be welcome. The person who put the ad up responded but it was on behalf of a friend. I can't text as the phone doesn't talk to me as the computer does. (I know they have a speech function but it isn't very good on mine). Hopefully the owner will call or email.

They did say it's WRC.

 

Thank you for that. The pics without the stripes are from the current ad. Looks like the current owner has painted it and addded the bridgedeck.

They cut off the cabins

If it is a tourismo 9 that's encouraging.
