I need to find some information on a Coast 34/35 sailboat which was made in BC Canada. I have been able to learn that the vessel was constructed by Marquis Marine of BC Canada but that is all. I cannot not locate any additional information on this company or any details as far as its construction is concerned. The boat is a traditional canoe stern boat GRP. I am trying to ascertain if the vessel has a cored hull and/or deck and what the core material is if any. I have exhausted all of the research resources at my disposal with no luck. Does anyone know anything about it. Any information would be greatly appreciated.

Fellow members,

I recently conducted an insurance survey on a 1973 Dufour 27 and discovered an interesting item. This fuse holder was incorporated in what appeared to be a lightning protection system. One of the back stay chainplate fasteners was attached to a grounding strap that was fiberglassed into the hull and led to this fuse holder which had a large fuse, about the size of a 12 gauge shotgun shell, rated at 400V. The fuse holder was not connected to anything. It is unknown what the holder was connected to. The vessel did not have a below waterline grounding plate. The bottom had been sand blasted to bare gel coat and no signs of there ever being a ground plate on the vessel could be located.
This item was concealed very well near the aft end of the engine compartment next to a bulkhead. I don't know if this was a factory or after market item. It was recommended to the client to remove this device and to install a lightning protection system in accordance with ABYC recommendations, but if anyone has seen this on a Dufour 27, I would be curious to know how the complete system was installed.
