I'm hoping to get some good advice from all of you out there about alarm systems for my 45' trawler and the do's and don'ts of leaving your vessel unattended at anchor. Let me briefly explain what I'm asking advice on. We would love to be able to anchor off some shallow water fishing areas and take off in our dingy for some fishing and sightseeing, but we're wondering if it is really safe to leave the vessel unattended at anchor. Do you guys out there regularly do this or do you always have someone on board or some kind of alarm system while at anchor? I appreciate all your replies. Thanks
