I will look for that - we have some units on the yard - but to big.
Hmm.. Handheld should work.

To complicate - we think about it. Make no sence to open the hatch and
leave the boat to.. : Nothing. Better let the hatch close and wait that the boat is on deck.

Most time question in the harbour of visitors is: Is that a robot (ROV) or manned ?
And if I talk: manned - the say : no never..
Peppers is really a micro sub. The hatch entrance is 240 by 400 mm. I have blue points on my arms..
I think Peppers with 10-20 % bigger will be a great machine.
At the moment the inside space is complete used and it was really
difficult to find a place even for the small picture of my girl..
Was designed to carry on trailer behind a normal size european car.
Can be much bigger behind a US fuel-eater..
The orignial boat has no top hatch, access via the dome. But this was not practical. Special on lakes.
And it is mostly used on lakes up to 300 ft.
I like the 5 Engines concept. I never worry if one of the thruster fails. Anyway if one of the sidethruster or one of the vertical fails - you can finish your dive or take another one - just with bigger turns and lower accent or decent rates. If I should build Peppers again it would 10 or 20 % bigger and has a double engine concept also for the mainstern drive.
6000 ft is not comon for me here - or I had to build a big drill to
this kind of boat to make the Sea here 5000 ft deeper..
Merlinsub@t-online.de would work all the time.
best regards Carsten
