[QUOTE="Rat, post: 140306, member: 1914"] Adding foam WILL help with flotation, that's why we add it. I believe you were told about upright flotation, in which case foam actually increases draft because of the added weight; and water displacement is the primary buoyancy factor. However, when you aren't displacing water (ie SWAMPED) is when you need the foam. I would add enough foam to offset the weight of the Alu. you will be adding. Probably filling the void under the sole will be more than enough. If you can give me approximate weight of the added structures I can tell you how much foam you will need for upright and level flotation. Looks like you will need to invest in a good jackplate as well. Your motor is hanging way below the bottom of the hull; looks like a longshaft motor on a shortshaft transom. You want the anti-cav plate even with the bottom of the hull to begin with; though it seems like most end up with it a little higher than the bottom. A jackplate is the ticket, you will be able to find the sweet spot easily with it. someone also built a homebrew jackplate on here; if I can find the thread I will post it up for ya. Nice find on the motor, those Yammi's are gold I hear. Gonna be sweat when you get her done. I like the matching trailer to BTW. [/QUOTE]
