    I was thinking of building a dive trail in one of are local artificial reefs . This reef is extensive so a 7000 foot length would be a major project and awarding . Every 50 feet hammer down a 6 foot steel fence post multiplied by 140 = 1.4 tons . I think a lift bag is not safe or simple...

    Wing made from PVC pipe.

    I also was toying with this application for hauling heavy and bulky loads . It is a wonder that nobody has designed a independent rigid flotation ballast system for equipment intensive diving . A lightweight two compartment pressurized tank would do the trick .

    A Battery Module

    I plan to build a battery module for my DPV using Honda hybrid cells . They are very robust and less hassle than lithium but much heavier . Cells are about 50 watts a kilo so a 1000 watt module will be 40 some pounds . I can play around with voltage and motors with my DPV projects .

    Building a DPV

    To answer some of your questions Gsk3 where the motor is located and in that position , it has been designed as a external thruster diver craft . The biggest problem has been the upward torque , so having the thrust close as possible to the hull has eliminated most of that problem . I...
