Might check with Blue Heron on his napkin bracket calculations. My guess is that he was including a flotation bracket in his calculation rather than a Porta-bracket.
I think Porta-brackets are fine for skinny water and shallow-draft, flat-bottom boats but me thinks this is a bad plan for a 25 deg dead-rise hull that wants is ass end out of the water in the big pool.
I'd talk to Don Herman at Hermco before spending a wad on Scott's product and ruining a perfectly good boat because a rogue wave caught your arse crossing the bar. Just a thought  |
Mcgillicuddy, Thanks for the input... The debate between Twins and Big Singles and the so called Flotation brackets vs non flotation is beat dead.
I for one just look at the math... In a so called flotation bracket you need One Cubic foot of Air to float 63 lbs... Add a 150 lb bracket you need 2.5 cubic feet... Now try and float a 495 lb engine on top of that and you need 10 cubic feet of Trapped air for balanced flotation...
I guess IMHO and it's only an opinion that Flotation brackets cannot create positive flotation... but I will say Don makes Kick Ass brackets for sure but I looked into them and between 3,000 and 4,000 bucks vs the porta with 17 Inches of verticle travel for $2900.00
The main issue is outside of one Person no one has added a bracket to the back of a 25 Seafari... I have to believe that Heron has his #'s right since mine were as close... Even taking into account the so called Cantilever effect the 600 lbs on a 26" Set back is not to far off of 2 outdrives hanging straight out the back and 1100 lbs of engines.... I am going to be really curious to see how she squats once the bracket is on with a 250 HP.
Someone here has to be a Guinea Pig and I am signing up for it... The worst that can happen... I have to remove the bracket, Notch the Transom with a 30" Foot Motor and Glass in a Splash well to Preserve the Integrity of a Full Transom...
This should be interesting to See what happens... can always add some kind of balanced Ballast to the Front as Needed to Level her out...
Thanks Robert
