Seafari Stern

[gaulois]

Im sorry to beat to death the "stern seaworthiness" of the Seafari. My 23CC was virgin, and had the well around the outbord. This was very effective if a wave washed over the stern. The 20seafari does not have such a well designed stern protection. I think I want to build something to minimize this problem. Any suggestions?
I inherited my dads 18 foot 1964 Imperial a long time ago. This is pretty much an unknown boat, but it was extremely well built. Actually built in Hollywood FL.
There was no bilge, a totally sealed deck. But there was an upwardly angled cover where the motor was mounted with outlets so that if a wave did wash over, most of the water would hit the transom and wash off and what was left would drain out.
I took this boat in heavy seas, and since the bow was covered, and it had a "step v" it took on 4-6 relatively well. If for some reason my engine had stalled, and I had trouble putting out a "sea anchor", I would have been ok for a little while had my stern turned toward the oncoming sea.....
This probably all sounds stupid, but I do plan on crossing to the BS, and Dry Tortugas, and in my dreams Cay Sal. I have done it before in the 23 (not Cay Sal), and the 20seafari seems very sea worthy aside from the stern problem.
Any suggestions would be greatly appreciated.
By the way, whoever sent me to info on the 140 4 Johnson- thank you- that is a great price.
