Do they make a jump starter for a ski boat?

I have a 10 year old Mastercraft ski boat and last week my battery died on me out in the lake. I was in a cove off of the main part of the lake and it was a few hours before someone came by too tow us back in. If I had a jump starter on board, I could have just jumped the dead battery and been on my way. Every one I have seen is made for car. Is there a jump starter out there that is for marine use?

Thanks for your email. Yes, there is jump starter specifically made for marine use on a boat. It has a portable 12 volt jump starter with 100 vac power inverter for marine market. It also has Marina switch as a safety precaution for wet conditions. and 4 foot cables for easy access from engine boat compartments. It is also small enought to fit into most boat compartments and will give a good solid jump start out on the lake.
