Have you considered buying rather than renting?
We did that and it saved us money. We were going to rent last June for two weeks.
The cheapest deal I could find on a boat we liked was $3500 plus insurance, so about $4200 for two weeks (which I think was a smoking deal, by the way).
Instead I bought a boat with no money down, financed it for 15 years, and have been paying $200/mo since. So about $2K plus maintenance ($800) and tires for the trailer ($300). So as of now, we're still into it less than renting.
That said, I want and need to sell it because we bought another boat that's much bigger and has a wake tower on it for the kids (which the first one didn't have).
So, if I am allowed to present this here, take a look. I'm happy to move it to the Garage sale forum if inappropriate here.
Selling: 2015 Regal 1900 ES with less than 47 hours on it... practically brand new.
It's a bow-rider (google it) and the "Premier" version (so it has all the options including piano gloss black hull, nice Bimini, and oversize swim platform).
It has the 220HP Mercury and Alpha 1 outdrive, the most powerful V6 combo you could get it with.
I paid a certified mechanic last August to do a full servicing on it including oil, filters, fuel separator, engine check, outdrive oil, cooling impeller, and even replaced the shifter cable bellows and cable.
It hasn't been used since, other than testing and running the engine on a set of ear muffs to keep things lubed (We bought a larger boat for our family).
It'll run WOT about 47-48 mph at Powell (GPS tested) and I have a 17" brand new Mercury Black Max prop (never used) I'll throw in for nothing (use it when you need torque or are carrying a lot of passengers with gear).
Cleaned up, it's pretty much pristine, and comes with a single axle aluminum trailer. Both tires are brand new, as is the spare purchased from Firestone last July.
It was sold new for $40K in 2015, and it has a suggested NADA resale value of $32K.
I'm willing to sell it for $25,000 because i need to clear it off my books.
If you financed it with no money down for the max time, your monthly payment will be about $200/mo, and insurance will be about another $300 a year, with an annual service bill of about $500 for typical maintenance.
In other words, you could buy it and make payments for a full year for the same cost of renting one for a week or two... and at this price I bet you could turn around and sell it in a year or two for the same price you paid, maybe more if you keep it in really good shape.
It's currently on consignment at Sun Country Marine in Phoenix, but I haven't had any good offers so far and I'm getting to the point where I need to sell it or start using it again...
Maybe we should keep it and use our new boat as the "Powell Boat" and keep the Regal as our Phoenix boat LOL.
