I'm considering buying a used 18' Sea Ark, Aluminum, Jon Boat with tunnel
hull and center console. Can anyone give me any information on these boats.
Reliabilty? Any problem areas?
I have looked at their web site for some time and by the looks of the size
of their company I would imagine they make as good a welded aluminum Jon
boat as anyone.
I know that Xpress makes a 16T and 17T that are suppose to be very good
tunnel/prop Jon boats. The 17T can be ordered with a Modified-V bow as well.
It is 56 wide at the bottom rear and is rated for 60hp max.
SeaArk has two sizes of 18' tunnel prop Jons.
1860 (0.100" skin) 60" wide at bottom/rear is rated for 60hp max
1872 (0.125" skin) 72" wide at bottom/rear is rated for 80hp max.
Tunnel/propeller hull flats fishing boats are popular in the Gulf of Mexico
in TX and in northwestern FL and in the Bahamas where there are miles of
shallows with few 'rocks'.
Most of the prop tunnels (5-7" high) aluminum Jon boats are flat bottom
which can be pretty rough in any chop at all. I would wonder if someone
makes a 6 degree bottom? Lowe makes a jet tunnel (3" high) models that have
6 degree bottoms.
I would say by what I have been able to figure out is that about 90% are
