Many thanks for your detailed reply. Your real world experience resolves a lot of theoretical, abstract musings - mine included. It sounds like the Blobster is fairly seaworthy. In re-reading Michalak's hullform essay on his website, I see that the Blobster uses one of his best hull designs, but in a blunt bow variant.
If you don't mind, could I ask a few additional questions about Blobster in this public forum? If you (or other group members) prefer taking this to private email, I have no problem with that. But I think this information could be helpful to others who are considering a Blobster build. Anyway, here goes...
1. The following photo shows your Blobster during its powered sea trials:
In the photo, the bow sets well above the calm waters. You are seated to the rear of the boat, and the engine wake suggests a moderate amount of throttle. Is this the normal trim for the boat while under sail? Or is the bow elevated more than normal because you are sitting towards the back and the throttle is opened up?
2. This photo is another shot, from a different angle, of powered sea trials:
Michalak's design does not have a full transom across the back. Instead, it is partially cut down to accommodate the rudder and outboard. As a result, the freeboard is rather thin on the left transom. Has this ever been a concern while under sail? Have you ever felt that water might wash over the transom in a following sea?
3. This photo - the final one (thankfully) - is an early construction photo, showing the two sides of the boat, cut from plywood and butt-jointed together:
In North America, plywood sheets measure out at 4 feet by 8 feet. As I understand it, in Australia you have metric plywood, that has measurements somewhat close to 4x8. It looks like the fore and aft side sections each require almost a full length of a plywood sheet. Is this correct? Was there much scrap left over from the end cuts?
4. Finally, all boat designs require a series of compromises, the result of which is that no boat can be perfect. While the Blobster has a number of fine qualities, there must also be a few areas where it is lacking. Could you share your views on some of the Blobster's weaknesses?
Many thanks Miles for sharing your Blobster expertise.

I am very interested in building a Blobster next year. Actually it is now more than interested, I am planning for it.
I have watched and read all I can find on the Blobster and I am quite convinced that Jim Michalak has come up with a great design here. As with many things, looks alone might put a would-be builder off, and this has been the reaction I have received on the boat building forums as I have been discussing the requirements for my next build.
From my perspective I am looking for a versatile, roomy, seaworthy boat that can sail everywhere except for true blue-water cruising. I live in Adelaide, and my local waters are either the local gulf waters which are semi protected but still can be rough at times, and the lower lakes and river Murray. I love sail-camping, and have plans to take her on extended trips down the river (somewhat like a compact houseboat), and will possibly even venture over to Kangaroo Island when the weather forecast is suitable, knowing that if caught out she will be able to weather all but a severe storm, based on all I can find from Jim Michalak's comments on the design. Of real interest is the clever way Jim has dealt with ballast. 270kg of water ballast which is easily variable to the conditions is a real plus, particularly when considering the difference in draft and ballast requirements between river and coastal sailing conditions. I can visualise on a river trip pulling up to a shallow bank with a few inches of draught and walking straight out onto the bank, or even with a gang-plank if it is a raised river bank (which can be a real issue when looking for campsites).
A couple of questions if you would. Firstly, have you found that the flat open bow is any issue when sailing in rougher conditions? From the design it looks like she will ride up and over all but the steepest waves, typical pram style. Has this been your experience? Would it be worth considering a gate for the bow or even even some kind of temporary bolt-on bull-nose or something for the rougher conditions? (I had thought of trying to modify the design for a sharper bow but this seems fraught with complexities!)
My plan is to rig her as a chinese junk with a mizzen. (For looks, this will make her look more like a sampan, quite in keeping with her overall appearance!)
I would love to be able to correspond with someone who has built one of these, and would appreciate any advice or suggestions you might be able to offer.
