Collar System

5.1. General

The collar system is of a design covered by the U.S. Patents developed and owned by

SAFE Boats International regarding the use of foam for the stabilization of watercraft.

The collar system also provides redundant buoyancy above and beyond the airtight hull of the boat, rendering it virtually unsinkable.

The collar is 100 percent foam, and no air is used. The closed cell polyethylene foam is shaped to the required geometry of the hull. The foam does not inherently absorb or retain water. The foam is inserted into a 1.1-kg (40-oz) per square yard blended polyurethane membrane collar that is reinforced with a woven polyester base cloth.

The water contacting surface of the collar is protected by an aluminum performance fin, which protects it from damage and enhances the handling characteristics of the boat.

5.2. Inspection

Inspections should be performed daily after each use to ensure no damage has occurred. Both the upper and lower collar flanges should be snug against the collars. If there are gaps, the flanges can be closed tight to the collars by using a five-pound dead blow hammer.

The exterior should be checked for punctures or delamination. Small punctures in the collar are difficult to detect due to the excellent memory of the polyethylene foam. In the case of a blunt force impact, damage may not show as punctures or tears.

Contact SBI at 360-674-7161 with any questions of concerns before attempting collar repair.

Refer to Table 0-a for collar material and specifications and Table 0-b for collar test specifications.

5.3. Foam Repair

If collar foam is lost, follow these instructions for the addition of polyethylene foam for repair. Call SAFE

Boats International (SBI) to ensure correct method of any repairs. Use only polyethylene foam provided by SBI. Refer to Table 0-c for foam repair procedures.

Tools needed:

• Patch foam

• Razor Knife

• Heat Gun

Table 0-c. Foam Repair

1. Verify that all loose and damaged foam has been removed.

2. Remove and foreign material, such as oil or grease.

Figure 0.d. Foam Damage

3. Apply heat gun from safe distance and at lowest setting to dry out foam around repair area.

Figure 0.e. Heat Application

4. Prepare the patch layer(s) of foam by cutting to the general size and shape of the area to be repaired.

5. Warm heat gun for five seconds on the highest setting.

6. Hold repair section of foam in contact with the deepest area to be repaired.

A high heat setting will melt the polyethylene foam and further damage area.

For ease of repair, work with thin layers of foam, even when repairing deep gouges.

NOTE

If first experience heat welding, test on piece of foam prior to attempting repair.

NOTE

CAUTION

7. Maintain a distance of 3-inches between the heat gun and the material to be patched.

Figure 0.f. Heat Welding

8. Once material begins to bond, work the heat gun out with a continuous side to side motion.

9. Repeat bonding sections until void is filled.

10. Trim excess foam from the patched area until flush with surrounding foam.

11. Verify the damaged section has been completely replaced and is flush with the surrounding foam.

Figure 0.g. Foam Preparation

12. Reinstall the outer fabric membrane.

The bond will be immediate once heat is applied.

5.4. Fabric Repair

If the fabric of the collar becomes torn or punctured, repair using Table 0-d for fabric repair using tools shown in Error! Reference source not found. or Table 0-e. Practice with spare fabric before attempting to repair collar.

Figure 0.h. Collar Repair Materials

1. Patch 4. China Marker

2. Tape Measure 5. Scissors

3. Heat Gun 6. Rollers

Table 0-d. Fabric Repair

1. Verify area behind the tear is dry and free of any foreign material.

2. Ensure area to be patched is clean.

3. Warm up heat gun for five seconds.

4. Roll while applying heat between layers.

5. Being careful not to burn or overheat the surrounding fabric, work the roller back and forth until entire patch has adhered to the collar.

Figure 0.i. Patch Repair

6. Allow the patch to cool completely prior to running the boat.

Figure 0.j. Repair Patch

Refer to table 4-5 for foam repair.

Practice with spare fabric before attempting to repair collar.

The heat gun has an adjustable temperature range. The most used heat range is between 75 to 100 percent of its available power. The higher the heat the more rapid the adhesion, increasing the necessity to move when applying the patch.

Patch should overlap the tear or puncture by at least 2-inches.

NOTE

NOTE

Table 0-e. Fabric Repair with Clifton Adhesive

Recommended Safety Precautions:

• Work in a well ventilated area

• Chemical resistant gloves

• Organic eye fume respirator

• Eye protection

Environmental Conditions:

• Ideal ambient temperature for gluing: 75 degrees F and below 50 percent humidity

• Maximum humidity: Do not try to mix and apply glue if the humidity exceeds 70 percent

1. Area must be cleaned and rough edges of material trimmed off to ensure patch will adhere securely.

2. Measure and cut repair patch to size, ensuring a 1-inch overlap around entire repair and round the edges.

Figure 0.k. Repair Patch

3. Verify patch covers entire damaged area.

4. Center patch over damaged area and tape in place with 2-inch masking tape.

5. With patch held in place, use 2-inch masking tape to mask off the area surrounding the patch. Ensure complete coverage surrounding patch.

Figure 0.l. Mask Around Patch

6. When masking is complete, remove patch.

Figure 0.m. Masking Complete

Do not buff the fabric down to the threads.

7. Thoroughly buff all contact/gluing surfaces using a sandpaper wheel, 150 or 180 frit sandpaper. Buff off the fabric shine.

Figure 0.n. Buffing Area

8. Repeat buffing on adjoining surface of repair patch.

9. Clean the buffed surfaces with PVC cleaner, using a lint free towel. Allow to dry.

10. Apply one thin, even coat of adhesive to each surface, using a stiff bristle brush (the 4-ounce can has a brush in the lid). Allow it to dry at least 3-5 minutes.

11. Apply another thin coat to each surface.

12. Although the material may be bonded while wet, optimum results are achieved when waiting 3-5 minutes before bonding the surfaces together.

13. Carefully align the patch and press both surfaces together. Apply pressure to the entire glued surface using a roller. Roll every millimeter of patch in multiple directions, working from the inside to the outside of the patch. This step is important because it forces air bubbles out and helps the two pieces of material bond.

14. Use a lint-free towel and PVC Cleaner to wipe up excess glue.

Figure 0.o. Setting Patch to Collar

15. Using heat gun with a temperature between 200 degree F and 300 degrees F, wave heat between adjoining glued surfaces as they are rolled together. This forces any air bubbles out and meshes the two fabrics together.

16. Roll from center out to ensure adhesion and smooth application.

The surfaces to be joined must be dry prior to applying adhesive.

Figure 0.p. Adhering Patch to Collar

17. Remove all masking.

18. Ensure all patch edges are adhered securely.

19. Allow to dry completely before placing back in service.

20. Complete drying time takes approximately 24 hours.

5.5. Collar Removal

Follow the procedural steps in Table 0-f for collar removal. Read through the instructions completely prior to beginning the removal of the collar.

Table 0-f. Collar Removal

1. Remove the capture plates located in the personnel recovery cutout and on the aft end of the collars. Retain all hardware for re-installation.

5.7. Collar Installation

Follow the procedural steps in Table 0-h for collar installation. Read through the instructions completely prior to beginning the installation of the collar.

Table 0-h. Collar Installation

1. Place one of the compression bladders

(4, 5, Figure 0.u) flat on the ground with the valve facing down.

2. Place one compression panel (1, Figure 0.u), on top of the bladder.

3. Place one foam section on top of the panel. Center the foam and panel on the bladder both length and width.

4. Place a second compression panel on top of the foam.

5. Lay a second compression bladder on top of the second compression panel, centering it with the valve up.

Ensure all loose paint is removed.

6. Slide the entire assembly into a compression sleeve (3, Figure 0.u), locating the air valves in the cut outs provided in the sleeve.

7. Repeat above steps for the remaining sections of foam.

8. Use the provided air pump to fill the bladders, being sure to alternate between the two sides to keep them roughly equal in size. Compression will be more effective if the bladders remain balanced in size and pressure.

9. When the bladders have equalized in size, begin elevating the pressure to 5-

7 psi. Check the pressure frequently as the bladder is inflated. Do not inflate over 7 psi.

While sliding the assembly into the sleeve, take care to keep the air bladders centered.

Figure 0.u. Collar Compression Kit

1. Compression Panel 4. Compression Bladder

2. Compression Panel 5. Compression Bladder

3. Compression Sleeve

10. When the pressure has reached 5-7 psi, note the time and set aside for a minimum of 24 hours for sufficient compression.

11. Spray silicone into the lower extrusion.

12. Center the end of the membrane on the bow tension ring and attach using the provided bolts and Nyloc nuts.

Work from the middle of the ring outward in both directions. This will keep the membrane centered on the ring. Keep the fabric tight as the capture band is installed in order to ensure a wrinkle-free fit.

13. Insert the lower pocket of the membrane into the lower extrusion

(Figure 0.v), working from the bow to the stern. Keeping the weight of the collar and the bow attachment flange up will aid in inserting the lower pocket.

Figure 0.v. Collar Lower Extrusion

14. Insert the bow attachment ring (Figure

0.w), into the bow as the collar is slid forward into position. Install bolts, washers, and nuts. Do not tighten all the way; finger tight is sufficient.

Figure 0.w. Bow Attachment Ring

Check the air pressure of the bladders after 20 to 30 minutes.

Fill as needed to maintain a minimum pressure of 3-3.5 psi during compression cycle of 24 hours minimum.

Chapter 5. Collar System

15. With the bow attachment flange loosely secured, go to the aft of the collar.

Using the attached pull strap, pull the collar back into position so the cone seam lines up with the end of the extrusion (Figure 0.x).

Figure 0.x. Aft Extrusion

16. With the pocket tucked into the lower extrusion, insert the lower keeper rod (

17. Figure 0.y) into the pocket through the aft end of the lower extrusion. Spray silicone onto the rod and into the pocket as it is pushed into the pocket.

A soft faced mallet or dead blow hammer can be used to tap the rod into the pocket as it becomes more difficult to push with increased friction.

Figure 0.y. Lower Keeper Rod

18. Using the attached pull strap, pull the collar back into position so the cone seam lines up with the end of the extrusion.

19. With the seam located and held into place, and lower keeper rod installed, install two 40-millimeter (1 1/2-inch) long No. 12 screws through the lower extrusion (Figure 0.z), and into the lower keeper rod. Holes have been predrilled.

Figure 0.z. Lower Extrusion

20. Starting at the bow, begin tucking the upper rod pocket of the collar into the extrusion. Work from the bow aft using the attached pull strap.

21. With the pocket tucked into the upper extrusion, insert the upper keeper rod into the pocket through the aft access hole (Figure 0.aa). Spray silicone onto the rod and into the pocket as it is pushed into the pocket. A mallet or dead blow hammer can be used to tap the rod into the pocket. It becomes more difficult to push with increased friction.

Figure 0.aa. Aft Access Hole

22. Once in place, twist the aft end of upper keeper rod to remove the aft section of rod (Figure 0.bb), from collar pocket. This allows for insertion of foam.

Figure 0.bb. Upper Keeper Rod

23. Clean the back of the main foam sections with a broom or brush in order to remove any loose debris or foam.

24. Mask the upper and lower edges of the foam with 2-inch masking tape leaving an area 50-centimeters (20-inches) wide exposed.

25. Spray the exposed area with foam adhesive.

26. Remove all sections of foam from the compression tubes and spray one side of the foam with the adhesive.

Do not tuck in the pocket aft of the upper extrusion rod at this time.

If re-installing the foam, it will be necessary to remove the 15-centimeter x 15-centimeter (6-inch x 6-inch) wide sections of foam off the back. A saw can be used to shave the foam off. If a short saw is used it may be necessary to slice the 4-inch thick foam down the middle lengthwise with the collar in order to remove it in two sections.

27. Place the compressed foam (Figure

0.cc), onto the main foam sections and press firmly into position. Ensure full contact over the glued area.

Figure 0.cc. Compressed Foam

28. Open the collar up as much as possible. Spray silicone into the forward portion of the collar, coating the inside of the fabric and the side sheet of the hull.

Figure 0.dd. Open Collar

29. Place the long section of foam on the ground oriented with flat side vertical.

30. Spray the aft end of the forward section with adhesive.

31. Spray the forward end of the short section of foam (contains personnel recovery cutout), with the adhesive.

32. Butt the end of the short foam to the long foam and press the two together, aligning the ends to avoid a misalignment in the joint.

33. Hold in place for three to five minutes until adhesive sets.

34. When the adhesive has set, remove masking tape and place the forward end of the foam into the collar (Figure

0.ee).

35. Insert foam. Periodically lift collar into place to assure a smooth installation.
