Im buying a tracker grizzly 1448 jon boat from bass pro. Im gonna put a 20 hp mercury tiller on there. The grizzlys have a premade deck and i was wondering if it will be stable enough for me to stand up and fish. Im only 5"7 140 lbs and i just cant fish when im sitting down i have to stand up. Let me know what you think

I have a 1542 and can have 2 guys standing up on the benches no issue. The grizzly will be more stable than my boat. I say go for it. Welcome to the forums.

Width is always a big factor...wider the better.  I have a 1552, which gives me a bit more stability over a 48", but mine is very stable.  I have also head that stability may differ a bit on mod-Vs versus a flat bottom, but don't have the experience to sway an opinion in one way or the other.

so you can stand on the front deck and fish easily

On my flat bottom, oh yeah.  My Alweld Jon is an LA model and is built with a very large front deck.  I have a pedestal seat that I usually fish from but can stand when I want to to stretch my legs and such.

You're about my height minus a few pounds. I can stand up and fish on just about every little boat I've been on. Those Grizzly models are supposed to be very stable. I don't think you will have any troubles at all. My boat in theory should be less stable than yours, due to the width, and stability is never an issue even with two people.

Wider bottom width = greater stability

And no mod-v bottoms are no less stable than flats!

I'm currently fishing out of an Alweld 16' 52" mod-v tunnel, handle 3 people with ease!

Yep,  Ive got a 14 ft alumacraft v-haul with a front deck.  No problem standing up and fishing by myself or with another person on board.

I have a Grizzly 1448 w/deck, no issues with standing.
