I’ve decided to build my Steve Neill U-212 as a dynamic diving boat, at least to start with ( I can almost hear the hoots of derision and howls of laughter incoming…) but there is a major reason for this. Present finances won’t allow me the luxury of the proper BigDave WTC unit for it, so until I am in a better financial position to spend some more cash and top up BigDave’s bank account, for the time being 212 will be diving under power only.
The idea is to build in a (temporary) home brewed WTC of sorts, using a length of clear Lexan tube from these guys http://cgi.ebay.co.uk/ws/eBayISAPI.d...rkparms=tab%3D
a small ballast tank powered by a screenwash pump to take on just enough water to go from surface trim to decks awash and then to dive the boat from there. That will give me a built-in failsafe because the boat will have sufficient buoyancy to return to the surface should things go wrong, so all isn’t that bad.
OK, two questions then…firstly, how much of which diameter Lexan tube do I buy? And how do I calculate the size of the ballast tank and the required amount of water to get from surface trim to decks awash?
Stood standing by…..
