Bayliner 4788 1999 Bahama cruise ready.


$ 169,000.00
Ft. Pierce Florida
Boat Type:
4788 Pilothouse
Boat Name:

 Fresh bottom paint, etc. New Salon and pilothouse AC units 10/17. This vessel isn’t a dockside ornament, she’s actively cruised in the Bahamas.  She has a new port engine/ transmission . New oversized bow thruster. 2014.

I’ve known this boat since she was new, sold by Duncan Marine Center in Charleston  in 1999. I was first on her when still in the ownership of her original owner back in 2014 in Charleston, just prior to her current owner purchasing her..  The good news is that they DO actively cruise her to the Bahamas so they’re on top of her systems.  I found NONE of the “normal bugaboo’s” these 4788’s are prone to, with the exception of her davit. It’s frozen and likely 90% of all the other 4788’s and 490’s on the market. It’s a known issue, that’s easily cured. I have the PDF file of instructions for repair if you would like to do it yourself. I also have a link here on my site to a local Davit Repair guy who just fixed the davit on the 04 490 I sold here in town.  These davits are heavy, and need be taken to a machine shop to be honed, the R&R is 90% of the labor charges.



Anyway- this boat Trillium does NOT have any leaks in her salon, nor any traces of ever having any on her valances. Her owners state there is NOT any water coming up through the rub rails. Her foredeck was solid, and her pulpit felt strong. Her exterior aluminum was NOT all corroded. .  Her FLYBRIDGE upholstery is in very good condition. Her flybridge dash is in very good condition (covered), she has two Bimini tops up there, which provide excellent shade. She does NOT have a dingy.

Her pilothouse HAS new upholstery (vs the original factory dark blue which has faded and/or cracked on other boats that still have it) and it looks great.

Her ICEMAKER in the salon DOES work, which is a rarity.  It does have the original carpet in the salon, which is clean, but I would view this as an opportunity to install the hatch in the salon as many owners have EASILY retrofitted, and install NEW carpet in her.. The salon upholstery is fine. Her bedding is good, she still has the original post and doors that allow for a private third stateroom.

She DOES have a  ‘oversized’ BOW THRUSTER.  . If YOU have a bow thruster installed on a 4788, expect to pay anywhere from $8k-$15k depending on who does it.


When the current owners purchased her, their survey discovered engine issues, to which the previous owner to installed one new engine and a transmission (hence the low hours) and do any needed engine work on the other.

She’s been reupholstered. This looks much better than the factory Navy Blue, which by now on most other boats is sticky, faded, and/or cracking.



A “tell” of condition is finding the original flybridge cushions still in excellent condition.


The Bridge Entertainment Center which was a $3800.00 option when new. You can’t find these ‘aftermarket’.



She has the original factory barrel chairs, and the factory salon table. If you don’t see these on a boat, that should raise an alarm of “where did they go, and why?”
