220 Dauntless T-Top

Postby jklaiber1 » Wed Feb 01, 2017 10:41 am

Hello. I may buy a newer Boston Whaler boat. I have found a 2007 220 Dauntless that seems to be pretty nice. However it does not have a T-top. I was hoping to get something in the 20 to 24-feet range with a four-stroke-power-cycle engine and T-top.

Did [the 2007 220 DAUNTLESS] boat have the option for a T-top[?]

Would it be possible to add one?

Any idea what the costs would be?

Any help you could provide would be great.

Thanks

In my understanding, Boston Whaler boats that have T-tops have been very carefully engineered for the stresses that attachment off the T-top will cause on the hull, and the attachment points have been appropriately chosen and reinforced. What is not known to me is how Boston Whaler would have fabricated a hull that was not going to get a T-top option when finished. If all hulls were fabricated with the necessary reinforcements in them for attachment of a T-top, then it would be reasonable to infer that a 220 DAUNTLESS that did not originally have a T-top could be fitted with one.

A second concern is the availability of the OEM T-top. Again, my understanding is that Boston Whaler T-tops were also designed and engineered very carefully to have appropriate strength and flexibility so that when attached to a hull the T-top would not be stiffer than the hull or vice versa.

I believe the best answers to your questions will be given by Boston Whaler customer service. They can tell you if the option was available, if a boat without the option would have been fabricated in the necessary manner with appropriate reinforcements, and if the OEM T-top is available as a separate item to be installed by the customer.

In general, you will probably be better served if you look only at boats that have a factory-installed OEM T-top. Re-fitting a boat with a T-top where the boat was not originally designed for that particular top structure can be difficult and may produce unsatisfactory results. Wind loading from a T-top can be very substantial.

There was an optional T-Top.

You can see it's design and part # from the Resources Section of http://www.BostonWhaler.com. Specifically, it is sheet 4 of 5, Final Assembly and Options, 2007 Outrage 220

http://www.bostonwhaler.com/boat-ownership/resources/

It is feasible to add a t-top after original manufacture.

I would use the design drawings when you contact t-top fabricators in your area. A basic t-top could run 4-6k, not including installation and options.
