Building catamaran in Maryland

Hi there! Quick question for those in the area and who built their cats. Trying to work all of the logistics before proceeding to a long journey, but can't find any info on that. Found marina that can handle the 26 beam cat (good for launching).
Question is is it possible to transport the cat of that size to that marina, looking at the area to purchase the land and set the shed there for build. I know it's a big mountain to climb but I'm determined and will build the boat one way or the other, would love to be near my location which is Potomac, MD. Will be building it with my cousins and oldest son so about crew of 4-5 of skilled home builders and I personally work a lot on auto and motorcycle suspension mods. All of the tools are available. Plan is to build Grainger's 48 raku cat. Please if you know anything or someone who's done it let me know, I'd like to do my homework.
Cheers, Yev

Good luck. great choice of vessel. Can't help re area as I am based in Australia. Make sure you shed is not too far from home making daily travel an issue for building.

Re: Building catamaran in Maryland

You'd be wise to find out what the plans for land developments are anywhere between where you plan to build & the water. Ditto on the stringing of new electrical lines which the boat might clip in transit to the water. As well as narrow turns, etc. So it's worth talking to some trucking/boat moving companies now. But even with all of this research, odds are in 5yrs there will be problems you couldn't have predicted. So some of how large of a pain the above depends on how long the build takes.

As to the work site, you might also look into renting a lot in a light industrial yard, or some space in one if you find a company in one that has some extra room.
They're fenced lots, again, inland. Where you can just have a lot. Or phone, water, power, etc. as well. And I've rebuilt a few boats using them in SoCal as they were much cheaper than boatyards, & didn't mind dust & noise at odd hours.

Regardless, at the worksite: buy a cheap RV or mobile office for the site, & a porta-john. And poof, a place to live where you can build on the (relatively) cheap. Also one option for a decent workshop are the "portable" industrial metal buildings, which can be assembled by a few guys in a couple of days. Though in MD, given the weather & seasons, you'll need a fully enclosed shop/shed to build the boat in.

Also, post this, & other build queries over at www.BoatDesign.net/forums as there are plenty of pro builders, & advanced amateurs who are members there. And if you find any other sites of interest, please let us know. Ditto if you start a blog on the build. Which one, now cached, one is on the building of a Farrier 44 Supercruiser catamaran. I say cached, as the boat's now done... after almost a decade of building F-44SC Catamaran

Another tip is to look into some of the courses offered on building using composites. Both via the Aerospace industry, & Marine industry. Everything from the basics, to vacuum bagging, to infusion. And also plenty of ones on systems design & installation, such as to meet ABYC standards.

EDIT: Subscribe to Professional Boatbuilder magazine, it'll have articles & resources which will be a big help to you. And their back issues are great too www.ProBoat.com
Plus many boat designer's websites have a slew of helpful links, & are worth browsing for same.

Also, it would be great if you could post the links & names of information sources you find to be helpful. Along with useful little building tricks, etc.


PS: On the design, is she primarily built using the flat panel construction style, much like Schionning's Arrow series? Perhaps even being available in kit form?

Re: Building catamaran in Maryland

find somewhere warm and dry otherwise your stored materials will go moldy after 3 months ie plywood.
also particulary important is the storage of fiberglass cloth which in damp/humid conditions will absorb moisture at an alarming rate,making it useless due to its water content.
this goes for composite nidocore/polyeurathane boards as well.

a used shipping container,insulated with dehumidifiers would suit this purpose,and save you thousands in damaged materials that have become unusable.

Re: Building catamaran in Maryland

Congratulations on your choice of design. It's quite a striking looking vessel; beautiful.

It does look like a flat panel design, which will save lots of time. If I had it to do over, I'd certainly lean that way, and I'd strongly consider a kit as well. Building isn't much fun, for me; so getting the structure finished and painted, quickly, would make things much more pleasant.

That boat's going to be very fast.

I have no information about building in Maryland, sorry.

Good luck.
Paul.

Re: Building catamaran in Maryland

Check with the local road authorities regarding requirements for oversize loads. Assuming it's some 2 lane roads, it should still fit (obviously confirm if there are tight spots). They may require police escort or other requirements (at your cost).

Re: Building catamaran in Maryland

It's BIG fun moving catamarans from one place to another. NOT.

Permits.

Police.

Crew

Power Company workers

Special trailer

City workers to remove and replace traffic lights

We live out in Frederick County and I was building a 40' cat until a health issue (surgery to replace thumb joint and advanced Osteoarthritis) arose that brought everything to a sudden halt. I had already built a 62x26' hoophouse, had tools, epoxy, first delivery of marine ply, etc.... What I did:

1. Made sure I had room for the hoophouse on our property.
2. Made sure the neighbors were clued in; some contributed/offered right of way for a tractor trailer to cross their land to get to the road (in the country here!)
3. Contacted the DMV who gave me the name of a company that takes a car and plots out the route from you to the water (Baltimore in my case), making sure you can get under bridges, etc.....
4. Contacted a local trucking company, showed them the plans, dimensions. They had a low-boy and a truck crane that would lift it and set it on the low boy with chafe protection.
5. Found a place to launch off of 95 in Baltimore
6. Found a marina that could handle the beam
7. Woke up in searing pain, found out about my hands and that if I started building I *might* last a year, got a bottle of Tequila, made margaritas, tore it all down the next day, listed it all on Craigslist, sold it and planted trees.

Sad day, but a good decision for me. Best of luck for the next 5-10 years. I have a friend making fairly good headway on a Voyager 40 from Bernd Kohler; he's in his 6th year.

Re: Building catamaran in Maryland

Wow thank you guys for all the input!
As far as material will be used is foam core (Corecell, divinycell, airex etc) with vacuum bagging method using S-glass fiber cloth and some carbon fiber for reinforcement to keep her light. For power Oceanvolt will be used with big lithium bank and solar panels
along with a small power generator in case if needed. Two AC units, water maker, fridge and a small cooking stove is a must everything else is optional and probably will be skipped. Now the real problem is how to transport and where to build, I don't think transporting it through some tight spots is even an option. So I'm looking at lots and land right near that marina and still need to drive there one weekend to look at surroundings and talk to people at that marina if there is an option to build major components at home then transport it there to put her together. Another option but I'm not sure if it's legal to buy a land with the water front access, build it there in the back yard and when it's ready call up the crane to launch it from my property ( I know it sounds crazy but possible?). I'd build my own ramp if it "is" legal so I could put and pull the cat out of the water whenever is needed and store it in the shed. Lots of research to do before I even buy the material. The shed will cost me around $35 - 45K and will be climate controlled. I know nothing usually works the way we want it to but I'm trying to think of every possible scenario.
Downunder: you Aussie folks know how to design boats/houses well, admire your style!

UNCIVILIZED: All valid points! Raku48 is mostly flat panel design except for bottom of the hulls that have no hard chines as Tony stated, they way they are build is to strip plank the bottom, flip it up install bulkheads and then the rest will go on top. I've looked at Schionnings arrow and it's impressive how fast people can build them but not a fan of design and talking to Tony Grainger was really pleasant experience. So when everything comes to the point to build I'll hire the project supervisor from local marina who's specializing on infusion and work on composites. For now I'm talking to a guy who's currently building Schionning 1500C version using corecell and vacuum infusion in Netherlands. Lots of good info he is posting on facebook daily and amazing build that is close to completion. Look him up on facebook using "Tri-Cat Sailing - zeilmee.nl" his name is Paul, working by him self with his wife. Very nice guy.

atoll: Thanks for the tip, I'll make sure that the storage and environment is top notch before proceeding.

svquintana: I hear you on challenges of building but I really love working with challenging tasks, at least for me it beats seating at home in front of TV. I'm really forecasting it to be a long project at the same time as efficient as possible. Found local CNC matching place, would be nice to let them rout all of the flat panels for build while working on hulls and jigs to save time. Adn I hope she'll be fast as we intend to keep the front of the boat empty only with water tanks, two double beds will be on the back of the hulls and no junk or storing bikes up front to keep her light and fast.

GordMay: Thank you and hope to contribute in the future!

valhalla360: Yep that will be the task, so far reading all of the county roads and limitations.

Cotemar: Amazing pic's is it in France? I don't think our movers will do something like that or even have capabilities. So far I've called two and after giving them measures was denied

LeeV: Sorry to hear about your experience, hope you're doing good even though people I know with this problem told me it's day to day thing. Thank you for advise, it may as well be Baltimore if Annapolis falls through.

Re: Building catamaran in Maryland

In Europe they have special tilting cargo trucks for the purpose, I have not seen them here in the US. You might want to complete 2 or 3 pieces and completed at the marina where it will be launched. Good luck, there are numerous problems along the way in building a boat, particularly a cat. Good design, if you are at it full time with help you are looking at 1-2 years, if its part time a lifetime.
Wish you all the luck and enjoyment.

Re: Building catamaran in Maryland

Duflex is great to work with, very light and strong.

Best of luck with your project.

Some photos of my build here: Member Galleries - Cruisers & Sailing Photo Gallery

I would suggest that if you go with electric drives, you fit a genset big enough to run both motors at around 2/3 power continuously.

There seems to be a tendency to fit very small generators. There's a Schionning Arrow recently launched that can only motor at 4 knots for any length of time. In flat calm conditions.

Pushing into 20-25 kts, he's going to be lucky if he can steer.

Re: Building catamaran in Maryland

Keep in mind that you can build many of the boat's smaller parts in a quite "tiny" space. Even a garage. And that many builders will assemble many of a boat's components in a shop at or close to home. Then moving them to a boatyard/close to the water when it's time to connect them, thus turning things into a large structure (complete boat). And that with many cored composite boats this is relatively easy to do. Though it's also possible with some timber boats as well.

With some designs you can even go so far as to build the hulls, & bridgedeck cabin assembly "at home". Then move them to a boatyard, & do the final assembly & paint there.
Or even fully build the boat "at home", then cut it apart at designer approved locations, move these parts to the boatyard, & then reassemble them there.

Yes, there are some limitations & compromises with the above, but they're worth looking into. As well as discussing with a few designers.

After 4 years building you only cruised for 7 hours?
