Welcome to RIBnet carus007
I have a similar sized "tender", but with an airdeck that gives better performance underway. Mind you, I have a 9.8hp motor
Don't mind the comedians on here, the boat you are looking at isn't the best choice for what you want to do. Ideally, you are looking for a minimum of a 3.2m SIB (soft inflatable boat) with either a wood/ali deck or an airdeck, paired with a 10hp motor - preferably two stroke.
Your budget means second hand, but if you stretch it a touch - it should be doable. Older SIBs sell for very little money, not so older engines.
Talk it over with us. Some of us will be helpful...
