Re: [PSUBS-MAILIST] Fiberglass Hull

[MerlinSub@t-online.de]

I take a look in that boat yesterday on the Düssedorf Boat show. 
Onne single seater and one double seater in production. 

Its fiberglas and rate to 50 meter with a saftey factor of about 5. 

The two seater is funny. To pressure hull, one for each person in one outside 
casing - but no conections between both pilots hulls - maybe a cable intercom. 

Fiber dont rust - but under longer water exposure and without a good protecion surface its gets "wet" and can lost 30% or so of it strength..
