Boat Forum / Building / October 2003

I'm about to settle on a slightly larger boat - moving from a 18ft clinker
fishing boat to about 23 ft.  During test drive ( what IS the right word for

OK, but in neutral it is still turning the prop, ...

Yesterday, I was applying two by four doublers to one or two rafters
and perlins in the roofspace of the homestread, cracked or broken
after half a century's service. I left one doubler stud overnight,
with some Titebond carpenter's glue applied to one face.

I test my DBC liferaft every year. It inflates quite nicely each time, every
time. The fluorescent orange "tent" covering material has developed a black
mold in numerous places.  The mold is right in the rubbery fabric and will

Any idea where I can get scaled drawings or digital images (side
views) of the latest 4 stroke outboards (115 to 140 HP range). I have
obtained some installation dimensions with a sketch attached but these
are for a range of outboards sizes and are poor quality. I was hoping

Does anyone know of any website that specializes in custom
reupholstered boat seats?  I have back-to-back boat seats & possibly
interior in need of reupholstering.  I'd like to get some ideas for
different color combinations and designs and if possible, I'd like to

hulls and liners?
Thanks in advance,

Does anyone have a source for spline weights/lofting wales.  I am gearing up

I need to re-install a diesel tank.  It was foamed in place and an then tab
glassed to the top of the bulkhead and hull.  No problem with the glass work

gallons.

I'm replacing the water pump impeller on a 1980 Johnson 70HP 2 stroke.
When I removed the pump housing, there was a small (1/2" long, 1/8"
diameter) round, bullet shaped piece of metal laying inside.
Does anyone know what this piece is,  and where it fits ?  

Whenever I read opinions, they tend to be given from the standpoint of "I
believe in method A as opposed to method B"
What I need to know, before embarking on an expensive and time-consuming
build project, is some good advice on the relative strength and longevity

   I'm looking for books, articles or websites that refer to canoe design.
I'm a part of a group of students that will built a concrete canoe. More
