Hello all  boat  bilders  out ther my name is H?kan
Im a Swedish botbilder on the island Orust knewn for bots  like
Halberg-Rassy  Najad  Afrodite Mal? and others. I hav ben asked to install a
Bow Truster in a 50 fet long 40 tonn hewy ketch. My company   AB Orust Marin
& Interior has made  som  chacges in the interior and noww the oner wants to
instal a truster. Non of the meny yards hear vats to do it.
Properbly due to the lack of experions with Ferro Cement boats. I Promist to
se iff I cud do itt. And i will iff i kan find out iff itt is posibel and
advisibel.

My  plan is siply to do itt as iff the bot was in fiberglas. I vill use
epoxy  nott polyester. I will fill a small distans betwin the drumm and the
hull witt a elastik mastik type Hybrid. I sel off a kompartment so  i can
fill the distans undet the tunnel to giv the boat stringth in case itt
rammes some thing or hitts a rock.

Tanks  for reading  thiss I am dyslektik and I prefer bildig bots befotr
wrigting.

After you work on that boat you need some English lessons! I would
rather see that you install the thruster tube in the same manner
as done in a steel hull. With the steel substructure in ferro you
should be able to flange in a steel tube bolt it and bed it in mastik.
The best way would have been to do it when the boat was constructed.
I just hope your firm has Lloyds behind you if this thing sinks.

OK, somewhere in the translation- well if you were over here you might
perceive this posting as coming from one of the occasional jolly jokers that
do a little comedy here.  I clicked on "source" and yep it's from Sweden,
Hakan really does have to figure out how to drill a big hole in concrete and
putty a bowtruster in. Use a lot of putty and get management to sign off on
the job before launching.  Anybody know how to say "hammerdrill" in Swedish?
Maybe find a surveyor that would recomend against doing the job.

I understood your english fine through the accent in text.  I am a naval
architect working on a ferro cement boat and the owner wants to install a bow
thruster also.  I would make a flange on the tube also and (thru?) bolt it to
the hull.  Make sure the concrete is sound on the surface also.  Maybe
strengthen the surface with epoxy coating befor applying the mastic.
Interested to hear what you try and if it works.

Good luck

Karl

Yes, I understood him as well.

To the ignorant jerks that thought the original poster's message was
funny:

I have a son and a business associate that are both dyslexic. The
business associate is an award-winning industrial designer.  He could
not write in _English_  as well as the Swedish guy-and he has been
speaking our language all his life.

If you think dyslexia is funny you must really bust a gut over other
genetic disorders. Maybe cystic fibrosis must really have you rolling
in the aisles?

Get me any ten boat guys, line them up and say the words"ferro-cement boat"-
how many of them cracked a little smile? The other element of humor in
Hakan's post was the job he got handed, lot of guys would have tried to bail
out. See, if Hakan was writing about a wood boat, exact same post, he would
have got straight answers, wood boats are serious.  Actually the answers he
got had some good advice in them. Why do I think Hakan and his buddies at
the boat yard probably give it to each other a lot worse than what he got
here, didn't Vikings kind of invent "guy stuff"?

I thought H?kan's post was hilarious, not because of the dislexia (I didn't
notice any dislexic constructs) but because his accent actually shows
through in his writing. I had no trouble at all following his meaning
and found the style delightful. Welcome to the newsgroup H?kan, I hope you
become a regular.

Regards,

Bruce

I see the biggest problem as cutting the hole without damaging around it.
Concrete is a brittle material and tends to crumble. There may be someone in
the area who does core drilling with diamond tipped core drill that has a
core drill of the right diameter. This is a tool that will cut a clean round
hole through reinforced concrete with no damage to the edges if done
correctly, and if it is mounted right it can cut into an inclined surface or
curved surface no problem. It is cooled with water, so no contamination.
Good luck with the project Hakan, let us know how it works when its done.

Well  i will cutt tis hole  on way or the other. Ven i kutting  in fiberglas
we us  steal shaft  and fix a smal rotor on a arm so we kan sving the axel
arund  and gett a hoal with out bilding komplikated fixturs. I dont trust
the cement hull for bolr binding  so i think i vill use  fiberglastube and
fasten itt with Epoxy lamiat.
