MSR 10L Dromedary water bags were patched with Seattle Fabrics wide Velcro using 3M 76. The Current Designs Solstice Titan was masked with 3M masking tape then spread with a thin coat of 3M 5200, a matching strip of SF Velcro loop set into the hullís 5200.
The bag was filled with warm water, more than the patch area cleaned with toothbrush/DILUTE Palmolive soap then brushed rinsed several times with distllied water followed with a brushing/dabbing with clean cloths/papertowels, of rubbing alcohol.
Care is used filling bag with water warmer than room temp avoiding condensation. Low humidity and an operating hair drier set low is possible.
The bag area matching the hull patch is masked before and after carefully fitting bag to hull patch. An accurate hull form is possible but apparently unnecessary as a filled bag cemented to the Velcro fuzz patch fits securely onto the Titanís hull form.
3M 76 is shaken then sprayed out for 3-5 seconds before spraying bag.
We had 2 adhesive failures before a solidly cured and adhering velco patch. Test !
The photo shows nylon strap loops cemented to hull. The complete system straps bags down probably thru a covering fabric securing bags from sideslip.
2 bags are patched top and bottom for piggybacking.
Bags were tried during roll and reentry practice with
a light overload of dry baggage containing clothing. Bags did not shioft from the Velcro positioning. So Ďexpeditioní cruising with the strap system is a go.
The keel line strap is diverís belt and cam buckle, 2 X straps from corners are 1 inch straps, all from SF. The diverís belt and cam is use able for a paddle reentry fixture aft cockpit.
We found the SF sewable d-rings useful for bolt thru hull deck loops as the sewable is a built in washer whereas strapping is a PITA.
3M 5200 cures SLOWLY so plan aheadÖ.2-3 weeks. Remove NOT 3M masking tape whenever 5200 allows. 3Mís masking tape will be in the Solstice next year, use Duck masking.
Dark spotty areas near corner loops are mildewing but stuck on masking tape. Other white spots are in use particles then 5200 spots on bag fabric.https://picasaweb.google.com/102234459580640424681/SeaKayakerTITANKEELBAG#5866508915884488098
