That's a good story about the canoe.
Sounds likd you made better use of school time than most.
Btw what region are you in, from, intending to sail mostly?

On the subject of interior space:
I was having a browse at DIY boat projects online just yesterday and saw they were mostly all similar 40' plus cats.
2 things stood out from the build log photos. Firstlt, the cabin space is enormous. This is function of thd design and plans. Secondly, the buikders mostly were fairing and finishing every square inch of every surface of the boat inside and out to mirror polish.

These 2 points are actually contradictory to what boats shoukd be like. Traditionally a small sail boat ( as opposed to ocean liner) is going to be cosy and comfortably cramped. You have your berth and tables and cockpit etc, taking minimal space. Just suffucient for the job. Weights and windage kept low. Every spare inch is used for storage and so on.

So i see these bridge deck cats with large open areas huge dining suites, lounge suites big ovensm fridges, several double beds enclosed private cabins. This is not inline with traditions of sailing small boats,
It seems the fashion to try to sell people onnthe luxury of a five stsr hotel whils sailing.
I guess that is a challenge to try and make something like yhat, but i really wonder what the point is, other than selling and money values.

The other point is related, having to polish every sq inch. Again seems pointless except for selling points and showing off purposes.
I faired to mirror finish the rudder blades on sidecar, this was an enjoyable job to do, wasn't too hard, and had a purpose of sailing better.
Some people were spending 3,4,5 years doing only bog, sand and paint.
It's supposed to be a boat. Shiny surfaces where people walk and hold on to are infact going to be worse as it will be slippery.

I would have thought multihull sailors would have a bit more common sense and down to earth practicality than this.

Doug:

    When I was in 6th grade (age 12...1967), I
bought a Trailcraft
canoe kit for a 17' wood and canvas canoe, along
with a fiberglass
option, with money saved from my paper route.   
That was in late
summer before the start of school, and when school
started, I
asked the shop teacher if I could build it in shop
class (my first
year of shop class).   He agreed on the condition
that we copy the
pieces for anybody else who wanted to build.    
The result was a
virtual "canoe factory".  We built 14
canoes that year, and our
"canoe factory" was a featured article in
the local paper, and
even made the TV news.  



    The point here is that it would make sense to
"group build"
some of these smaller designs.  Form a local club,
and get half a
dozen builders involved in building their own boats. 
If you are
going to the trouble of making molds for entire hulls
or half
hulls, why pop just one boat out of it?    The
savings in cost
from buying entire cases of foam and large quantities
of epoxy are
extremely significant.



1/4 Divinicell:   $80.82 per sheet,

                        $67.52 in
lots of 50 sheets



Raka Epoxy:    $98 per 6 quart kit  ($65.33 per
gallon)

                        $746 per 15
gallon kit   ($49.73 per
gallon)

                       



                           
                               
   
                           
                               
   
               

    I don't consider that the HP fits my
application nearly as
well as a cat due to the much greater length required
to get the
internal area I want for a live aboard voyager in all
climates of
the world.   To me it's a tropical boat for
outdoor living, which
is great in the tropics.    The Wharram designs are
popular in OZ
and other outdoor living environments by the same
token, but the
more enclosed boats are more popular in the northern
latitudes. 
The smaller HPs are perfect boats for summer fun. 
Beach proas,
weekenders, cruising the Caribbean, Florida, the
Bahamas, etc.  



    It's much easier to get people interested
in a smaller more
manageable project than a 50 footer.  



                           
                               
   
                           
                               
   
            H.W.

To be a bit honest, i wouldn't mind a more
indepth
explanation of the steps involved. This will
vary with
each designer i guess. Reference books can add
to uuour
info source.

It is expected that a builder will have gotten
enough info
from sources like tgd internet already.



But on the other hand hp designs have probably
less to
learn to be abldd to do them.



I would like to be treated as a bit of an
idiot by the
designer, so tghat at least i would not miss
some of the
important things in th e build.



It would depend on what your background was.


Although i have done years now of building
with epoxy,
glass and so kn i have never infused or
vacuumed anything.
It was a level of extra effort that was not
botherddd
with.



That the whole new hp line is based on that it
means new
learning curves.



It means more detail to organizing and
preparing and
getting bertterf qualitg materials.

More of a labratory setting to build in that a
dusty old
boat building shed..



You need to go and enjoy getting dirtg
somewhere else.



A question for Rob or anyone:



The molds for a hull, say lw hull , is done
full length
(10, 12 or 15m for lw hull) or done with two
molds of half
length and joined after ckming out of
molds?



Saves a lot of space.

But you would need 2 molds made, mirror jmage,
and they
woukd need to be close copies as must meet at
joins.

Seems like one mold piece if space available
would be much
simpler.
