Buying a zodiac 650 pro or 600 srmn both with 150 hp yamaha 4 stroke

[norwayoffshore]

Hi,

Iam stuck between two boats,

2006 zodiac 650 pro w/2007 yamaha 150hp 4 stroke, geonav, flaps, vhf, targa, electric airpump, radio/cd/mp3, trailer and 2x two seat jockey side by side behind the console. 300 hours on engine.

2007 zodiac 600 srmn w/2004 yamaha 4 stroke. 2x two seat jockey ( one behind the console and one in front of the console ). Trailer, targa. 110 hours on engine.

What is the main difference between these two? Which would be the best boat overall?

The srmn has some kind of alu reinforcement from the floor and around the supports for the rear plate. But i suspect they have beem giving the boat a beating in heavily sea because i can see two small cracks in the gelcoat in the upper section of the supports on both sides. Should i worry a about this or is it normal with small cracks in the gelcoat? Also, i cant see the lower sections of the supports because as i said, they have made a alu reinforcement all over the floor and half way up the supports.

I use the boat for diving, long/short trips, hunting, etc..

Thanks !
