The issue is not boats in a berth sitting in the water. That one is simple since it is just a building covering a low level of storage. He is asking about boats stored on racks several levels high. It's a nasty item. No contractor in their right mind should attempt to DESIGN it. Even with the engineers copying designs from contractors in the Florida panhandle, LEAVE IT TO THE ENGINEER. Now I can say no engineer in their right mind would touch it unless the client was willing to make some very limiting modifications to the layout of the racks.

Many of the facilities have adjustable racks to accommodate boats of different heights. I've heard of people putting side wall heads in the columns to cover the area beneath the boats. You think maybe they were ignoring that you need the heads to activate in order for the water throw to count as covering the area? Group A plastics on racks with LOTS of surface area and LOTS of air flow is not a recipe for a slow burning, modest fire.

Speaking of racks, these also often do double duty by supporting the roof as well as the boats. You think they include the weight of a water filled boat as part of the load for designing the rack?

Are you having to prove the worth of sprinklers in this type of

Any idea of the value of loss in storage docks WITHOUT sprinklers?

Subject: boat storage

I know this subject has been thoroughly abused so let's try a different
angle.

Does anyone know of any successful saves due to a sprinkler system in a
boat storage facility?

This issue is not going to go away and there is only going to be more of
them built.
