That would have to be 10+ days / year....every year for a handful of years.Like most toys, renting looks expensive but if you are only doing it a few times a year, it will be far cheaper. If you are at 10+ days a year (or have specific location/timing restraints that are hard to satisfy by renting), you may come out ahead by buying.
I'm seeing the types of boats I 'like' (which means literally nothing) as I don't know poo.
Hell even my boss offered me his 90s bow rider for 5-6k (he's not sure yet).
Rent for $500/day (including fuel)....that's 10 rides where the break even point comes in (without including insurance, storage, etc). Add the requirement for a new truck to tow the thing...and renting is much cheaper.
As for the license...I'll just do it online somewhere. As per @oioioi are there free resources that anyone is aware of?
