Tips for Multihulls |
 |
 |
|
- Use
cut down plastic milk containers or old icecream containers
for resin, dont use tins or waxed milk cartons.
- Sanding
the boat is a major chore, search out and use the best
sandpaper you can afford. The yellow and green hardware
paper just doesnt cut it.
- Buy
a Rupes or Metabo orbital sander. You will be grateful
for their power, ease of use and long life.
- Use
at least 2-3 coats of epoxy on all timbers and ply as
a minimum. This is easy to skimp on but is totally necessary
for durability.
- With
cedar strip plank boat either run glass fore and aft
(hard to do). Or run glass across the hulls and use a
60mm plus width by 1mm deep rebate for glass overlap,
this will make fairing much easier.
- Use
the best 2-pack polyurethane you can find, expensive
paint is more durable and holds its gloss much longer.
- Buy
all stainless steel screws direct from large Wholesalers
such as Austain. The cost will be less than ½ of
a chandlers.
- Use
fibre reinforced plastic skin fittings, metal fittings
corrode and the cheap plastic fittings can snap.
- The
only mask to buy is a Sundstrom. You only get one set
of lungs (available Worldwide).
- Drum
sanders that fit into a drill are very useful & good
for sanding coves and internal convex shapes.
- Consider
employing a panel beater for fairing and spraying. Their
labour rate is cheap and they are usually suited to boat
work.
- The
cheapest most commonly used fairing compound is Q.CELL.
Available in bulk and cheap.
- Stick
to the well-known epoxy brands such as West System your
boat will have a higher resale value. We have found the
cheaper brands inferior in application and durability.
- A
digital smart level is an excellent tool for all those
BLOODY angles.
- A
good method for attaching bulkheads & benches etc.
Cut to shape and fix panel with small nails such as panel
pins, then use small dabs of hot melt glue to temporarily
fix panel in place. Remove pins and you can now apply
a neat continuous fillet.
- For
inside trim try vinyl and Prelude materials, they look
much better than frontrunner.
- If
you incorporate a Targa, consider using it as a boom
crutch. This works very effectively on my vessel "Subzero" a
Grainger 1250.
- An
excellent inexpensive water tank level indicator is available
from Carac. It works with 5 leads on a resistance principal.
It was designed for American campervans.
ON
DECK
- If
using a painted grey deck tread, consider adding a tiny
amount of green tint, the colour improvement is excellent.
- Fit
black plastic conduit to shrouds before swaging the tube,
prevents mainsail chafe.
- Dont
use second hand rigging wire or screws you wont
be able to insure the rig.
- Definitely
order an anodized mast. They almost last forever and
no respraying required.
- Fit
a zippered lazy jack sail cover. The best improvement
to sail handling devised.
- Use
an experienced sail maker. Our recommendation is GM.
Your vessel will have a higher resale value.
- Consider
getting your sails tri radially cut with cruise laminate.
They last longer and are more efficient than crosscut
dacron.
- For
the rails and stanchions make sure you buy your stainless
piping as 316 and well polished. This is available off
the shelf.
- If
your boat is white, then spray a 4 plus dark bootline.
Otherwise youll be scrubbing the waterline often.
- The
copper based epoxy antifouls dont work very well,
but they make very suitable undercoats.
- 12volt
electric toilets are the answer for large multihulls.
There cheap, dont block and good for landlubbers
to use.
- Place
the inlet and outlets for the toilets on opposing sides
of the hull ( for obvious reasons).
- Consider
a desalinator as multihull performance is directly related
to weight. Abundant water is a pleasure.
- We
have researched the various solar panels on the market
and were so impressed with the new Canon Uni Solar Panels
that we decided to market the product. The panels are
shade tolerant and even work when overcast. Dollar for
dollar these panels have a minimum of 20% output over
other panels available in Australia. With the added benefit
of no glass to break and a twenty year guarantee.
- Available
from Emultihulls at Australias best prices. 64watt shade
tolerant Panel only $600 inc GST.
