BOAT DAVIT INSTAllATION INSTRUCTIONS(MODELS: 600 LB. - 8,000 LB.)

IMPORTANT: Readthis manual carefully before installing the DavitMaster Boat Davit system. REFER TO LOCAL BUILDINGCODES FOR EXACT REQUI REMENTS. The following instructions indicate the minimum requirements neces­saryfor installing DavitMaster Davits onto aseawall,bulkhead, dock or piling foundation. Eachsituation must beevaluated based on existing conditions. DavitMaster is NOT responsible for the installation nor the integrity ofthe seawall, bulkhead, dock or pilings.

INSTAlliNG DAVITS ONTO A CONCRETE SEAWAll

locating Placement of Davit Foundations1. DavitMaster recommends placing the foundations 2 feet further apart than the centerline length of the boat (refer to Fig.1).2. Dig a hole according to size of lift and how much concrete is needed. (see Chart A). The hole should be dug directly in back ofthe seawall cap in order to obtain maximum reach. The hole must be of sufficient size to accommodate the amount ofconcrete needed.

Installing Rebar and Base Bolts1. Install REBAR(W') and anchor BASEBOLTS(refer to bolt hole pattern [Chart BJ,on back) per local building code requirements.Use a base template to hold base bolts in their proper position while attaching the base bolts to the rebar.NOTE: The base template (representing the actual base) must be placed as near to the forward edge of the seawall cap as possible.2. Holes should be drilled in the seawall cap to accommodate the front bolts (Fig.1).

Pouring a Flat, level Concrete Foundation and Installing the Bases1. Pourthe concrete, then level the concrete even with the seawall cap using front to back and side to side strokes.NOTE: The foundation MUST BELEVELfor proper inboarding.2. Allow concrete to cure overnight before installing the davit bases.NOTE: The davit basescan be bolted down the next day, but NO WEIGHT should be placed on the foundation until the concretehas cured for at least a week.

INSTAlliNG DAVITS ONTO WOOD! BLOCK OR METAL BULKHEADSPouring concrete for Wood, Block or Metal Bulkheads1. On all foundations poured behind wood, block or metal bulkheads it is important to use more concrete than with a concreteseawall. We recommend using approximately 3f4 to 1 yard additional concrete or more depending on the specific conditionsof the bulkhead.

2. To maximize the davit's reach on a wood bulkhead, we recommend a raised foundation extending over the wood bulkhead.

Installing Steel Beams for 4,000 Davit Systems and Heavier1. For boats 4,000 pounds and over it is recommended that one or two steel I-Beams, about 10 feet long be incorporated intoeach foundation and extended back into the yard to be a "dead-man" foundation.NOTE: The "dead-man" foundation supports the primary foundation.

2. Normally 112 to 3f4 yards of concrete in each "dead-man" foundation is required.

INSTAlliNG DAVITS ONTO A DOCK

CAUTION: It is recommended that dock mounted davits be restricted to 1,000 pound loads, assuming dock is of sufficient size(i.e., not just a cat walk) and is in good condition. DavitMaster is NOT responsible for the integrity of thedock construction.

1. Position davit base where you want it, then place bolts thru bolt hole located in the davit base.

2. Position a 4 x 4 board parallel with base bolts so that it runs between the first and second dock stringers (perpendicular to thestringers), (Fig. 3).

3. Mark position of each bolt on the board and drill. Fasten 2 x (depth of stringers) boards between each base bolt (Fig. 3). Now boltthe 4 x 4's into place (using base bolts). The extra stringers between each bolt will help to prevent warping of the deck boards.

INSTAlliNG DAVITS TO PiliNGS

CAUTION: It is strongly recommended that pile mounted davits be restricted to 4,000 pound loads. It is also recommendedthat a competent marine contractor assess the requirements needed for proper installation of davits onto pilings.We do not recommend pivoting davits installed to pilings. It i~ very important that heavier boats (1,000 Ibs. andup) not be pivoted on piling installations. DavitMaster is NOT responsible for integrity of pilings.

1. It is necessary to make sure that any pilings used for davit installation be at least 40" taller than the dock level. This is so that thedavit pile mount bases can be properly installed.NOTE: Depending upon the structure and integrity of the dock, pilings and boat weight, bater pilings may be needed to reinforceprimary davit pilings.

2. Stand pile mount davit base up against the piling and mark the location of the bolt holes.NOTE: DavitMaster strongly recommends inboard mounting of the pile mount bases (Fig. 4).

3. Drill thru piling (refer to Fig. 4 and 5 for bolt pattern).

4. Stand base up against piling and push bolts thru the mounting feet and piling. Tighten nuts down on the bolts.NOTE: On new piling installations shrinkage should be expected. Bolts should be re-tightened at a later date.
