Another small realistic feature which adds to playability is the storage compartment in the front deck, which could hold multiple accessories such as the rubber rings shown. Although I haven't included many accessories in the design, there could also be diving gear and other cool stuff.
The railings at the front might have to be adapted to work properly, but I think they have potential to be a great detail and an appealing design feature.
If you want this model in your Lego City, then give it your support!
PS. I understand that this model holds little appeal for all the AFOLs (adult fans of Lego) who want complex building techniques and minute details, but please give your support on behalf of people who you know would appreciate a model of this kind. Thank you in advance!
PPS. Please spread the word about my project, it may not have a licensed theme, but there's more to CUUSOO than licenses of films and product lines, its also about single model ideas, like this.
