New member here, hello to all.
I have a catamaran grp boat, 29"x 14", weight approx 2.3kg bare, that I will be fitting out for use as a bait boat for my foreign carp fishing, I would like to use a water jet drive system, have seen some information regarding 12v offset impeller pumps that can be used but I think that using bow thrusters would work using the same principle and would keep weight and cost down?
I am looking to use 2 bow thrusters for the propulsion inline fore/aft, each with own esc to give forward and reverse using tank steering method (or use mixer to give proportional steering from each unit) from transmitter. I have seen the graupner, robbe and raboesch units, robbe units will be too tall for the hull so I am leaning towards the raboesch units (16 or 19mm tubes) but want to run 12v SLA so this would mean removing the 6v motor from the raboesch unit and replacing motors with mabuchi 385 12v units. Will this work, hull will be sealed with a removeable cover to access the battery (12v 7 or 10ah) so am concerned about heat from the motors etc.
Boat weight is planned to be around 4kg unladed, 6.5 kg laden - will the use of bow thrusters give me enough thrust for movement?
Any advice appreciated, have seen/read that a few members have built bait boats and would welcome any alternative ideas - not too keen on props as this would require alot of fabrication at the stern in order to keep the props within the foot print of the hull - similar restrictions using jet drives.
Thanks in advance
Nick
