weight capacity issues of 12' v hull

Post by Shake n Bake » 16 May 2011, 14:43

Hi guys. I am modding a 12' aluminum blue fin v hull with a weight capacity of 564 lbs passengers and gear. I would like to add decking (2x2 frame 5/8" ply) both bow and stern and two pedestal seats. I also have a bow mount trolling motor, battery, 9.5 hp Evinrude, and a gas tank. I'm about 225 so Im a little worried the boat will be at or over the weight capacity. Anyone ever struggle with this dilemma before?

I think you will be pushing it, try to cut down on weight by using aluminum for the bracing and deck.

That is pushing it.......IMO if you didn't do any of the mods you would be well with in the weight range....it stinks but that may be your only option to carry the gear you want with you....If I had to choose between mods and bringing more gear I'd go with gear everytime.
If you need to find me I'm fishing.....just don't tell my wife.

A few thoughts.......

I've got a early 1970's Sears 12' semi v. The boat has a 585lb capacity on it. As of now, my mod has the following things in it.........

15hp Johnson - 76lbs
Carpeted plywood front floor (angle aluminum frame underneath) - 25lbs
Carpeted plywood tops on both seats - 20lbs
Carpeted top on the bow to mount sonar/trolling motor - 10lbs
45lb MK Edge trolling motor - 30lbs
Misc fishing gear/sonar units/seats/other electronics - 75lbs
27 series battery and and lawn tractor battery - 75lbs
2 bank onboard charger - 10lbs

This all equals roughly 325lbs before I get in the boat. I'm about 225lbs myself. Just by myself, the boat is fine even in rough water. It was a bit scary, but I got stranded on a big lake 2 weeks ago when the wind picked up and I had to make a 2 mile run back in 3' rollers. The boat did fine. With that said, when I add another 200lb person to the boat, it gets a bit hairy. Safe on small waters, and places where you don't have to worry about any whitecaps or bigger....but to be honest it's really just a bit small of a boat for more than one 200ish lb person in the boat. It's also not very fast.........I get 18/19 mph alone in the boat, and 15ish with another 200lb person in the boat......it's definitely a wet ride with two people unless the lake is glass smooth.

One thing I'd suggest is to use angle aluminum for the framing for any decking or floors. It's MUCH lighter, you don't have to ever replace it, and it's MUCH easier to work with than wood. It literally took me maybe an hour to frame my front floor with aluminum, all I needed was a cutoff tool, drill, and a cheapo rivet gun.

Hope this helps!

I have a semi-v 14 foot with a 15HP Evinrude...fully loaded with two people I get 17mph into the wind on the GPS and 18MPH with the wind at my back so your mph isn't that far off. Hopefully I'll be able to see what it will do with just me in the boat this coming week. IMO 18mph is pretty fast in a small fishing boat.

^^^ I agree. Basically, you've out grown your boat already. Hold off on any mods until the next one comes along. I would move the battery and/or gas tank forward if possible. Just my 2 cents.
