are catamarans easier to build than conventional v-hulls

I would like to know if this design can be customised to be 6.1 to 6.4 meters long with a 2.5 to 2.7 meter beam, with cabin layout to sleep 4 and still have room for fishing, plus have the option of outboard or inboard/outboard legs. AND do the plans include dxf plasma cutter files.

Is this the same boat as the Riki Cat shown in the construction area? If not is information available on the Riki Cat?

will this desin work with 2.7 meter beam?

I have been considering building a catamaran for commercial crabbing.I have been considering the z cat.However I know just how sea worthy these hulls can be.would the two up be suitable to use as a displacement hull for this purpose with twin 30hp engines on the extended version.
Also would the design be rugged enough or is this hull really only for pleasue use.

I see you are getting a lot of interest in single engine cats,
1, what are the associated problems with going to a single engine?
2, can they be cured by the fitting of a jacking plate?
3, if I purchased a plan and wanted to run a single outboard would you include a splitter in the plan?
4, Did cecil design that cab in 1954?
5, how does the built boat sit in the water ie, bow down, stern down or level?

could u give me an ide of what the performence would be wiht a singel 135hk if we modify the transum and place it in the middel ?? would it get her out of the water ?

can i build the 2 up by the information i get from the pdf files ??

can the two up be shorterned to 4.8m to 5.0m and made to 2.3m wide and run a single outboard

What would be the increased weight of using 4mm sheet for the bottom and side plates?
Would this impact handling and fuel economy greatly?

What is the waterline length of this Cat?

can this be shortened to 5.2 metres and fitted with a single outboard

i am interesting for vision cat
do you have plans?
whats the prize?
details?
