Pictures 1 & 2

  • We recommend you to use least 6 supports
  • Place the remote supports equal from each other along the boat.
  • If the boat is rig, add additional set supports to secure the boat in case of violent winds.
  • Use big wooden blocks or the supports of skittle under the front and the back of the skittle to stabilize the base of the boat.
  • If supports are installed on a loose ground (lung), we recommend you to place a piece of plywood below every support to prevent him from sinking into the ground.
  • Turn the support until it clocks towards the central line of the boat (pic. 2)..

Pictures 3 & 4

  • Adjust the screw of adjustment of the support with right angle of 90 ° against the hull (pic. 3)
  • Insert a safety chain into the small groove (* of piece Warehouse Marine: AMMAG43516), and aim slowly by pulling the support towards the back. If one of the pairs of side supports faces the skittle or if the skittle is long, cross the safety chain under the skittle then upward the other side (pic. 4)
  • For more stability in the bow, use a support with a head V.

  • Outstrip the side supports as far as possible to maximize the stability (pic.3).
  • For motorboats with bow V deep, we recommend you to use, in the bow, supports for sailboats (pic.4).
  • Insert the safety chain into the small groove (* of piece Warehouse Marine: AMMAG43516), and aim slowly by pulling the support towards the back. (pic.4).

Remark: never attach your painting / cover to supports, because she could move them by violent winds and put in danger their stability.



Quantity and size
How choose the good support as my sailboat?
Use least 5 supports. The recommended quantity of supports takes into account the length of the boat. For the rigged sailboats, we recommend an additional pair of supports. If the boat is very heavy to the bow or to the stern, we recommend you to use an additional support to support to reduce the pressure on the hull.
There is also a model with the head V which marries well shape of the bow.


Recommendations

<30' (9m)
5 supports
30-40' (9-12m)
7-9 supports
40-55' (12-16,5)
9-11 supports
>55' or more (>16,5m)
13 supports

There are sizes different from supports of sailboat for any sizes of 3' (1m) to 13' (4 m) of draft. Warehouse Marine has the sizes the most popular in inventory during the period of wintering.

AMMASBS-2
48" to 65" of height
AMMAG43516
G43 Galvanized chain 5/16''

How choose the good support as my motorboat?
Motorboats require a minimum of 4 wooden blocks or supports placed under the hull of the boat. We have to place these last under the room(chamber) of the engine because it is the heaviest part. It will allow to reduce the pressure on the hull. We recommend you to use a minimum of 4 supports for all the motorboats. For the large-sized motorboats (> 33 feet) add 2 additional supports for the support.

Recommendations

<30' (9m)
4 supports
30-45' (9m -13,7m)
6-8 supports
45-60' (13,7 -18,3m)
8-12 supports
>60' (18,3m) ou plus
12 supports

There are sizes different from supports for motorboats. Warehouse Marine has the sizes the most popular in inventory during the period of wintering. The use of a support for sailboat will more turn out to be effective in the bow for motorboats possessing a bow V lengthened. A support for sailboat in the bow and supports with driving boat in the back turns out the most practical combination for motorboats.

To make and to avoid

You will find in the following list the actions which you should make or avoid making during the installation of your system of boat's supports. This list will allow you to maximize the security any time. She does not apply in a universal way to all the users of supports by boats because of infinite variables in their applications. On the contrary, she must be used as complement to the already taken precautionary measures.

Never forget that the supports of boats serve to stabilize the boat and, the blocking of the skittle, to support the weight of the boat.


To make :

  • Use supports of skittle or blocks, along the axis of the boat to support the weight, always make sure that blocks are neither split in good condition that is nor mined by the decay..
  • Use boat's supports by side pairs, the one placed on the port beam and the other one on the starboard beam
  • Use chains to secure all the side supports of the boat, chaining the supports of port on the starboard beam
  • Use a minimum of four supports by boat, and a pair in every 10 feet (3m) for the longer boats.
  • Use a support with head V under the bow of everything of sailboats with skittle or with heavy bow.
  • Use a support with head V behind the skittle with fins or sailboats with heavy bow.
  • Use supports with boat on a firm ground and of sand; use a piece of plywood under supports in case of soft ground.
  • In the windy regions, remove the mast when you take up the boat on supports; if the mast cannot be put down, use additional supports.
  • Replace any damaged or rusty support
  • Maintain see them greased well to avoid the corrosion.
  • If you have to replace a support under a boat, install at first an other one there close by.
