Transport; Trailer Transport; Using Your Boat For Towing - Terhi Tender Eignerhandbuch

Smaller Terhi boats can be transported by car on a
sturdy roof rack. Larger models should be transported
on a purpose-built boat trailer.

5.1 Trailer transport

You can easily transport your Terhi boat on a trailer.
Make sure, however, that the trailer is compatible with
your boat. Check that the load capacity of the trailer
is sufficient for your boat, its engine and other equip-
ment. Terhi boats are very light for their length so
ensure that your trailer is sufficiently long to accom-
modate your boat. It should have an adequate number
of keel supports, and load bearing supports and all
these supporting points must have a sufficiently large
surface area, so that point loads do not become exces-
sive. This is especially important on small roller trailers
where there are few rollers as standard.
In transit, the engine should be in normal driving
position and the steering friction should be firmly set
(tiller models). However, make sure there is enough
space left to the ground. If there is a risk that the en-
gine might hit the ground while in transit, the engine
should be tilted up and supported with a separate sup-
port beam or detached from the boat.
WARNING! Do not transport the engine attached to
the boat when the engine is tilted up without having
secured it with a support beam. The engine or the boat
can be damaged, or in worst case the engine can fall off.
Check that the seat hatches are locked with their
security clips in place. Do not leave loose items or ex-
cessive loads in the boat during transportation.
Fasten the boat securely to the trailer, before com-
mencing the actual journey but take care not to over-
tighte n the fastening straps. The bow strap should
point forwards and downwards (the winch strap on
its own is insufficient for securing) and swaying of
the stern can be prevented by tying a strap across the
boat. To prevent the straps from marking the boat use

a soft material between the strap and the hull. Adjust
the trailer side supports or bunks, so that the boat can-
not move sideways. Clean all the supports of sand and
dirt, to prevent them scratching the hull.
Finally, check that the trailer is properly locked to
the trailer hook! Always loosen the fastening strap im-
mediately after transportation and when leaving the
boat stored on the trailer.
NOTE! The trailer's centre of gravity must be toward
the front. Make sure that the boat is securely attached
to the trailer. A swaying boat may strike a single sup-
port point, damaging the hull. The trailer's keel sup-
ports should carry most of the weight of the boat.

5.2 Using your boat for towing

When towing another boat, a buoyant rope of suffi-
cient strength should be used. Start the tow carefully
and avoid jerking movements. Do not overload the en-
gine. When towing a rowing boat, remember that it is
designed for slow speeds only. It is not suitable for fast
towing, as it will not plane.
WARNING! The towing rope is highly tensioned when
towing. If it breaks, the end of the rope can reach dan-
gerously high speeds. Always use a thick enough rope,
and avoid being in the vicinity of the end of the rope.
It is the owner's/operator's responsibility to ensure
that mooring lines, towing lines, anchor chain(s), an-
chor lines and anchor(s) are adequate for the vessel's
intended use, and that the lines or chains do not ex-
ceed 80 % of the breaking strength of the respective
strong point. The wear of the lines and the weakening
of the breaking strength due to knots/nodes should
however be taken into account.
