I sail Lake Michigan. I believe it may be advisable to purchase a raft in the event the boat became holed during a lake crossing. I have searched the web and more less settled on an Intex Seahawk II (supposedly seats 4 people and cost about $200). 99% percent of the time my sailing is solo or with one other person. The raft would have an electric DC pump. I have never seen this raft first hand so am interested in recommendations from fellow sailors.
