Mini40 trimaran "MOD40" with new (scale) C-Rigg

The "MOD40" is getting better every time. This is the C-rig which follows almost exactly the scale measurements of the real MOD70. It sails very easy now but you still have to pay attention as it wants to turn leeward most of the time. But I managed that she doesn't stop in the tacks as she did before. Speed feels good but that needs confirmation during racing. The next two MOD40 are in the middle of building....

Looks great mate, looks well balanced on one hull .can i ask why you have centre board sloped and starting from infront of the mast ? could that be causing the lee helm?? i tried a sloped fin on a monohull yacht and it wanted to lee helm and didnt like tacking .

The centerboard/foil must have full length in trunk when in down position otherwise building a strong enough trunk/blade combo becomes a challenge. The lateral loads of long board are primarily supported at hull skin and deck portions of trunk. In order to be able to have enough room to raise the board, forward of the mast avoids negative interactions with the boom.

+nuggsrc Usually those boats have vertical fins right behind the mast. This on is slopes to avoid to strong windward helm when the center hull is climbing. The more the fin comes out of the water, the more does the lateral center go aft. It works quite well! This is also scale, the real MOD70 has the fin at the same position with the same slope.

What's weight of it?
