Anchoring , Mooring And Towing - Ockelbo B18 Series Owner's Manual

Trim when running at speeds above planing:

When the boat is running at speeds above planing, the trim also needs to be
adjusted. As speed, direction, load, wind or wave conditions changes, new
adjustments may be needed.

Use the trim up to lift the bow up slowly without change of throttle position.
Follow the log to notice for how long the speed is increasing. When the speed is
not increasing anymore, the trim is in the most fuel-economic position. Then
lower the bow slightly to avoid the propeller loose grip.

In head sea (boat running against waves), you may have to use the trim to lower
the bow down to soften the vertical motions but be careful not to lower it too
much due to the risk of bow to plunge into waves.

In following sea, you may instead need to raise bow up to prevent nose-diving.

A safe ride is always more important than maximize speed/fuel consumption, so
always trim for safety first.
Trim when lowering speed to below planing:

When you reduce speed below planning, or stop the boat completely, the trim
should again be adjusted to a trim down position. This improves maneuverability
and makes the boat ready to accelerate fast next time.

NCHORING
Mooring, anchoring and towing require specific skills and good seamanship. Always ask
for advice when needed.
It is the owner's and operator's responsibility to ensure that mooring, towing and anchor
ropes, anchor chains and anchors are appropriate for the vessel's intended use and in
good condition. Wear and impact of knots should be taken into consideration. Also see
chapter 3.10 (strong points)
Mooring:
When coming ashore or mooring to a quay the boat must be secured properly. The
boat, when moored, should withstand high winds and rough seas. The boat should not
be moored with temporary fastenings if the crew is not nearby. Make sure other boats
cannot be damaged by your boat and consider the effect of the wake of passing vessels.
Mooring ropes should be long enough and as horizontal as possible. The boat should be
able to rise and sway without moving sideways. You normally need two mooring ropes
for both bow and stern. Only use the strong point cleats, not the stem eye or secure
eye. The ropes for the bow should be equipped with elastic shock absorbers and the
ropes for the stem should be about the length of the boat. The points of contact
between the rope and the clasps should be checked regularly for wear and tear.
Moor your boat carefully, even in sheltered places, because weather conditions can
change rapidly. Do not moor the boat with the stern facing the open sea, because high
