Today marks my son's 19th birthday... and today is the start of his own sailboat build (his B-day Present)...actually requested by him and designed by his Old Man. See...his girlfriend has a sailboat so he wants to learn how to sail and have a boat himself. (Gotta finish this before the inevitable GF change and the loss of interest). Below is the proposed design...kind of a quasi Cat boat but not quite as wide at 12 x 5 ft. I plan to fit it with 2 sail plans...a true cat gaff rig and a balanced lug. It can use the same sail but swap spars and mast positions. It will use a Daggerboard for now with the option of fitting a Centerboard later in a rebuild...we'll see. I hope to get it done for next year's Rend lake Messabout. Lots of the hardware will swap between my current build and his also so things will be redundant at the messabout in case anything breaks. This will include at least 1 new process for me... Scarfing the panels together. I have a 1:12 jig made up and we'll see if I can manage to not screw things up too bad. My LakeScow build runs apace with the interior all gooped up and getting ready to finish the deck bracing prior to flipping and finishing the bottom. I still hope to make my Sept 26 launch date although it might not have all the fixin's done. I'll need to get it out of the garage in order to build this one so I HAVE to get it done soon. I want his hull together before the snow flies.

I hope you have a backup plan for the aforementioned breakup.  :-D

Wellllll....I suppose I could use it myself...if it REALLY came down to it.

Lewis  Don't worry  about the mule, just load the wagon :wink: Bud

That sure is a nice looking hull you have planned!  Should be a nice load carrier with good stability.  I would suggest possibly a sharper entry at the bow like Welsford's designs just to help the hull cut through the chop on low-wind days.

Good luck on the build!

Thanks... I like it too. If you trim down the bows tho you run into issues with the plywood wanting to do it's own thing. Besides...it's supposed to be a quasi Cat boat and they aren't really noted for their needle noses now are they?

Wouldn't be right if he beat his old man's scow now would it? :shock:

Actually, traditional cat boats have a fine entry, typically with a good bit of hollow. The beam is carried well aft of course for bearing area, but the entry isn't bluff at all. Most cat designs also recognize the need to decrease all this additional wetted surface, particularly aft, so the bilges aft on cats were "low and tight". This allowed a reasonable exit at lower speeds while offering considerable power when pressed and the bilge turn became immersed.

The reason you don't want a substantial half entry angle, on a "fat" hull is the lee bow wave formed, will become quite large and the boat will develop a nasty habit of being "hard mouthed". Cats have to deal with this issue for other reasons, so not promoting it in places where it can be avoided, is usually a wise design compromise.

I think beating "the old man's scow" is a and should be a right of passage.
