Hi Antz
If for dam fishing, they would be ok.
Look like they would be pretty stable.
However, if you intend to cover a lot of water, that lack of rudder is going to be a problem.
The lack of rudder would be a problem if launching in the sea as well. Beaching , with no rudder, is going to be "fun".
Do you intend buying both or only 1 of them?
As you have stated, you will be doing both freshwater and saltwater fishing so I'd say rather have a look out for someone selling a secondhand Stealth or Erics, or something to that effect. At least this way once you intend launching at Ballito or St Lucia, you'll be kitted out properly.
At the end of the day, it's your decision and good luck with your purchase.
