Sabotina Build Setup

Dinghies, day sailers, world cruisers. Many small sailboats make ideal rowboats or low-speed power boats.

Sabotina Build Setup

Post by Muellerd » Sat Nov 17, 2012 12:08 pm

Just got the Book of boat designs and along with it the Sabotina dinghy boat plans.
I plan to build the Sabotina to gain some building skills before attempting a larger boat design.
Most of the Sabotina plans are clear except for the form setup.
Looks like the three forms have the sides staggered. In other words one side of the form has the side foward of the cross members and the opposite side is aft of the cross members.
Any one have input as to why this would be? Why not just build both sides of the form to the aft or forward?
I must be missing something here? :?

As a disclaimer, I built the hull, but never finished the boat. When I built the form, all the uprights were on the same side of the frame, forward of the transom and aft of all the others. This is vital so that, once the hull is sheathed, you can easily remove the form from the frames, and then remove the frames (except bow and transom, of course) from the hull.
Why build a boat?
Because they don't think I can!

Just dug out my Sabotina plans and had a look;

According to the instructions as I see it,You make two U shaped forms or "cradles for the hull to sit in. They can be any piece of scrap ply or particle board.The shape for these forms is taken off the patterns for the aft seat facing and the mid-seat-forward facing. They are mounted on a couple of 2 x 4 or similar stringers at the corresponding position in the boat ie. the aft seat facing form would go where that facing would be INSIDE the hull. Similarly with the mid-seat-forward facing. They will be at 90deg to the "keel'.
As noted you must make these forms 1/4" larger to compensate for the ply planking.
Remember, these forms or molds are outside the hull, so it sits inside them ant the hull is wired out to them to maintain the shape while filleting.
Hope this helps.
Doug

In the Customer Photos section, under boat builder photos, then Sabotina by D. Erich "Mouse" Marse, you can see some pics of the form and frames as I built them.

Thanks for the input everyone.
I think I am on track.
Just built a form table to work from and plan on starting the form this turkey holiday weekend.
Hopefully the epoxy and screws show up in a few days. Still got to get the wood though.
Will post picks once I get something going here.

Thanks again for the help.

I was building up the forms for the Sabotina and apparently had not read/seen a note next to the form measurements. "View left of centerline looking aft, View right of centerline looking forward" This totally explains why the cross members appeared to be fore and aft on the drawings. :shock:
I got all the form and frame measurements laid out on construction paper and plan to transfer to the wood today.
One thing I can't find is a measurement for the keel structure. From what I gather it should be 2-1/2 inches wide by 3/4 inches tall runnning the length of the boat.

Here's an update of my Sabotina build.
I have purchased white oak for the structure. I found that using the Poxy Grip is real user friendly and has plenty of work time. Granted the temps I'm working in are fairly low (50's to 60's).
I created templates using the measurements supplied from the plans. it took a while but was easy.

Got the frame work done and starting to add the plywood sides.
For this project I decided to use the 1/4" Sureply purchased from Lowes.
