I still have a couple of questions and a couple of comments:
In the open water capsize testing video on page one of this thread, do you remember how much water was left in the cockpit after righting her? It's impossible to tell from the video. Also was the water ballast in place for the test?
***There was about an inch I would say. Not really enough to cover the floor evenly, so perhaps a little less. Scamp #1 did have a few bugs to be worked out. One of which was a small leak somewhere in the vicinity of the port cockpit sump. A little water got below from this leak. In addition the two hatches in bulkhead #3 leaked a little more than I would have liked. Both of these issues were minor and have been or will be remedied by her owner. Capsize testing tells the sailor a great deal about his/her boat and gives us the opportunity to make improvements based on testing.
***The open water test video posted on utube is with ballast. Scamp was also static tested with and without ballast. I still have additional tests I hope to conduct in the near future, likely in May during the Small Craft Skills Academy in Port Townsend as I will be sailing #1. I had plans for fourteen different capsize scenarios (loaded/unloaded and with and without ballast) on different points of sail and in higher wind. Time and the cold conditions (this Pacific island boy got a little cold in spite of full dry suit) allowed a total of eight capsizes, 2 static and 6 open water.
One thing I definitely noticed from the video was that the rudder became airborne before she finally went over. I think one of the twin rudders that we have planned for the birdwing SCAMP should stay engaged a second or two longer than the single rudder in a capsize.
***I too noticed this and figure it doesn't matter much. Scamp wants to be sailed flat. In an extreme heeling (near capsize) situation she mushes along and doesn't seem to miss the rudder blade being in the water. I had thought to lengthen my rudder blade but figure as designed is fine since Scamp wants to explore shallow waters and as mentioned she wants to be sailed about as flat as any small boat I have sailed.
The other comment is that if I'm out fishing with my like new $1400 4 HP Yamaha on board if anyone thinks I'm going to even get close to capsizing my SCAMP while sailing home then they're even crazier than I am – and that's saying something!
***As stated capsizing is a rare if ever event for most sailors. Beginning sailors should learn how to avoid it and how to manage it should it happen. It is very good to know self rescue can be quickly and reliably managed aboard Scamp. Much like setting up and practicing reefing your rig self rescue skill allows greater confidence to sail further in varying conditions and situations.
Thanks in advance for your anwsers, kenjamin
