Comments:

Specifically designed to provide a state of the art offshore stock plan design. The past ten years has seen the introduction of wave piercer type fast catamaran ferries around the world. This type of design was generally resulted with conventional designs having rather straight up-right stem profiles, which give excellent performance but are rather visually unattractive. The Mack Truck look as one designer put it. The Z Bow concept has the best of both worlds, an attractive appearance and good performance. Pioneered in Australia and many of the countries leading Naval Architects have spent time working on these designs, known within the NA profession as "Z Bows". Boden Boat Plans have combined with Waterline Technology Naval Architects to bring this state of the art technology to the small catamaran scene.

Yesturday I Asked for a stable fishing boat in predominantly protected water and a centre consule model of the Z craft; I actually wanted a walk around consule;

Thanks

Is it possible to construct a trailable 7-7.5m Zcat? If so what horsepower would be required? Thanks.

Are (CNC) cutting files available for this design? Also, in general, are cutting files available for the other (alloy and steel)designs on your website? Thanks!

are you aware of the wave-piercers done in St. Croix by Gold Coast Yachts and Roger Hatfield? They started at about 38 feet and went all the way to 104 foot but ran into structural problems at that size.

Am I right in assuming PDF details are the eclectronic version of the plans? Thanks!

I have purchased the pdf pack and was wondering if you could send the basic CAD file as seen on your site. This would be most useful in exploring deck configurations. Thank you

Would it be possible to reduce the Z Cat to a length of sayn 5.4 (18')?

In regard to the aerial view I noticed that the 2 up has a rounded bow while the Z Cat has a chisel/wedge shaped bow which I prefer: Given both were going to be built at 6m which is your recommendation?

Regards

Tony

How would this alloy cat handle compared to a similarly sized fiberglass model?

Thanks for your previous response; Given a desired length of around 18'-6" to 19' what is your advice on the choice of boats for mostly protected water (recreational fishing)i.e. which do you think is more suitable the Z Cat or the Two Up and what beam & power would be recommended at this length?

Thanks again

Tony

What length could this design be extended to with out needing to exceed the max trailer regs? cheers.

I require a stable fishing boat mainly in protected water (bay) could I see the z cat centre console version & is this suitable or what do you suggest?
Regards

Tony

what sort of engine shaft length should be used for rough off-shore applications

I would prefer to build in Baltek or a glass/foam sandwich panel. Pro's & Con's for the Z cat using these types of material?
If sandwich panels are viable can you supply plans to suit??? Thanks

can hamilton jets be fitted with diesel engines to this boat

I would like to build the cat out of steel would this be possiable and what would the weight difference be.

Is it possible to downsize this plan, so that a boat of 5.5-6.0m could be built.

This craft seems to be a new design, what are the benefits of the wave piercing design appart from the obvious asthetic improvements.

Thanks for your patience; I am narrowing this down: What is the minimum size the Z Cat can be reduced to and do the wave breakers have to be on as I prefer the deck shape (aerial view) of this cat as opposed to the 2 up?
Thanks Tony

to ask the question in alloy Z Cat thanks for the great site,just wondering if you guys could suggest how to buy alloy at the right price to build one of your boats thankyou

A lot of cats suffer from tunnel slap due to small sponsan size, how does the Z cat fare?
What height are the topsides from internal floor measurements?
Is it possible to install larger capacity or extra fuel tanks in a 7-7.5 metre Z cat for long range offshore?
Thank you.

I have just ordered a PDF details pack of the Z-Cat. I hope it includes the suggested layout etc. of the hardtop version. If not, please supply such details.

I have a cnc cutting table. Would it be possable to get the files in .DXF format.

Hi,I am looking for a boat plan approx 7m suitable for offshore fishing with plenty of room for 4.I am undecided as to go with a mono hull i.e. the sea boat or go with the z cat.Can you explain the difference in handling between the two,& what would be your choice
also approx cost difference if posable. thanks dazza

what email address can i use to send an email to you ?

thanks for your reply the enlarged z cat with foward cabin as yiu sugest is what I,m after I will reseach the yamahas .They have come a long wa since I first sarted boating. thanks greg

how would this boat perform at displacement speads 2.8 m x 8m with less HP I would like about 12 knots

the extended version of the z-cat sounds like a good first build but then i would be looking for one more in the 60 foot size , any chance of that in the future?

Are plans for for a larger Z cat, say in the 9m range with more beam??

Are the hulls planing or sem-planing?

Is this the same for Two-up?

Are there any advantages other than the flash look of the wavepiercer compared to a conventional cat hull?

Which hull shape would perform best into a head sea and going 'downhill' with a big following sea?

What would be the upper weight limit of motors to maintain an even keel?
Would this change much if the length was extended to 7m?

Would the Z be OK as a 7M with 2x140hp Suzuki 4 Strokes @ 191kg each and 600l of fuel (4x150l tanks).
I preferably want a trailable Cat but OK for extended trips. If OK. can you give me an indication (approximation) of its draught with these tanks full and in a hardtop config. but otherwise unloaded. Would it be advantageous to include (add) a wavebreaker during construction.

I have heard that some cats are ''WET''. How would you rate the Z Cat and the 2 Up?

Comparing the 2 up and the Z Cat will there be and differences with handling at:

1. Picking up buoys
2. Wharfs
3. Getting on and off trailers
4. Running up to a beach
5. One man handling

Why is the Z cat 300kg heavier (50%) than the 2up but only 0.7m (12%) longer? I under stand the plating is 4mm but is this on bottom only or sides as well? Is the structure also a heavier construction? How is the displacement less than the 2up?

How hard is it to modify the Z cat to length of 18 foot and what do you think the hull wegiht would be also what would be the perfect outboad size


thanks

What length & beam can the Z cat be constructed to be better with larger capacity fuel tanks & room for long range offshore?
What size outboards would suit this (I would like to stay light & economical like the Suzuki 140-175hp)?
Would it be possible to modify to a walk through transom?
Thank you.

Further to the hull design and performance; could the Z cat be built with conventional 'mack truck' bows with the same waterline length?
I am more interested in performance than looks and guess it would be a quicker build.
