Tour boat design help needed - low wake, high speed, shallow draft ... oxymoron

What about this fire rescue Catamaran?

What are the specifications? I like the jet drives. With a different layout it can be a great tour boat.

Yes, and this boat is 3.5m wide, designed for railway transportation. We have developed 10m version of this hull, but not complete yet. This is full planning boat, not optimum for low speeds.

In general, for Your case it could be custom design - more expensive but serves the purpose.

I got it... Well just as an idea this is what I am looking for...sort of.

By the way I asked for a quote from a local boat builder to build a 10x3m M-hull out of fibre glass and this is what he gave me:

Plug: 37000 euro 8 month duration
Mould: 25000 euro one month duration
Hull: 13750 euro, 3 weeks
Decking - 5500 euro 6 weeks

How do you think they are? I have no clue and nothing to compare it to. I know is a dumb question but ...

Plug for 8 months??
For instance, this company built first 10m cat in 4 months, from loft drawing delivery, building set of molds... to launching. Yes, they worked hard...

Yeah... I was saying the same thing. They where working the mould old stile and than I asked about cnc mill for the mould ... there is only one in the country for that size and they have asked 3000 EUR to make 3d model so they can estimate the cost... what a joke.

Probably the 28-footer here would serve your purposes, but may be rough in larger waves. They can custom-build, so could probably add skirts to minimize wake.

If you want jet, specify the Mercury SportJet at a minimum (that is what the Phantom uses - it is basically a SeaArk Predator Jon with a Merc Sportjet), but the larger jets (e.g. - Hamilton) would be better for longterm durability.

Thanks for the Info. Those tour boats look great. I have been contemplating over that design and was looking at Trident tour boats that has round pontoons. I know they are inefficient but simple to build. The thing is If I build one of these boats outside the country the shipping will kill me. I almost bought a 35 feet Trident from US impounded one. It was a great price but shipping and taxes almost doubled the price...

This model http://www.mshipco.com/commercial/mo...yworkboat.html from M-ship suits my needs but in a smaller version. I might ask them to see what would be the cost of plans and all for such hull since they have one working. I could even settle for the same model if price is good. In aluminium I could build it here at a more reasonable price than fibreglass as moulds and plugs are a killer for short run.

What is a reasonable price to pay for such plans? I have zero experience here. Say for a 10mx3m aluminim hull the type seen at the M-ship link above?

Another thing I didn't mention is the engine must be central as the boat accesses narrow canals 4m wide sometimes and the water at shore line is not deep and full of vegetation. The single engine central installation is ideal in such situations. For that a catamaran will not work unless outboards are used.

When you choose Stock plans they are cheap...couple hundred dollar...when you go custom !! much more. Plenty of stock plans for all sorts of craft on the internet.
