There's a lot of very good boats in this size bracket.
My 2c, with the following to note:
We ended up with a 1550 so I'm biased, and we were looking for a runabout, but many of the observations still apply....
Commonly considered boats in this space...
Frewza F14, F16
Stabicraft 1550
FC435, 535
Surtees 495
Here's some various observations about each:
Stabicraft 1550:
Assuming the Frontier is the same up to the gunwales as the Fisher, has really good high gunwales at, off the top of my head, 720mm. This makes it feel very safe, helped by a full-height transom.
Optioning the boat, some things are very good value and no-brainers, some are ludicrously expensive.
Needs some grunt on the transom, 60hp is a good place to start.
Wing-style coamings are really good. With the stability of the boat you can sit on them, clamber around the boat when you're launching/retrieving, blah blah.
The Frontier gets the very cool transom setup with the full bait station with livebait tank blah blah blah. I wanted a Fisher with this setup but they wanted silly money to build one like that.
The tackle trays under the seat.... ehhh, take it or leave it. We got our Fisher built without them, same setup as the port side (with a hook for the IcyTek). I figure in 10 years when then trays are all cracked/smashed and Shimano/Plano don't make them any more it would be really annoying. I would seriously consider asking if they can built it with some dry(ish) storage with a hatch under the seat instead.
Extremely confident handling in a following sea. In a (reasonably big) head sea it's either very wet if you drive too slow or spine-ruining if you drive too fast. Staying in the sweet spot requires attentive driving and playing with throttle, trim, and heading a lot.
Also, the Frontier is ludicrously expensive, you'll probably be in to one for 50k+ by the time you option it up.
Surtees 495:
Oodles of space on the runabout, CC presumably the same. Very practical layout.
Lower gunwales at 600mm.
Stability is good compared to a traditional deep-vee tinny, but nowhere near that of the pontoons or gullwing hulls.
Full height transom, nice wide gunwales. Best baitboard setup in its class, especially if you pay the cash and get the enormous 900mm option.
Options were surprisingly well priced, you can really "pocket battleship" the boat without spending outrageous money.
Also requires some grunt, deep-vee with no chines means it doesn't lift itself super well, 60hp+
Probably the best ride into a head sea.
Frewza F14:
Way narrower beam than the others at 1.75m. Very limited flat floor space as well; the bottom of the hull intrudes significantly into the floor. Internal beam of only 1.2m means it's a 2-person max fishing boat, even in the side console.
Great value for money, highly customisable.
Unsure of the gunwale height.
Regular (narrow) gunwales.
F16: Way more boat than the F14, still slightly narrow in the beam but much more usable space.
FC435:
Wicked little harbour boat, arguably the best value. Base boat includes plenty of features, like the passive livebait tank.
Lowest gunwale height at 580mm.
Easily towed/handled, tow weight nearly 200kg less than the 1550. Also means it will go well with as little as a 40hp.
Low transom with outboard cutout, no outboard well.
Beamy for the length, fair bit of room, although you would need to be careful on the forward casting deck due to extremely low gunwales up the front.
Basically a sheltered waters/pick your days carefully boat. Probably very safe but they have no height in the bow so it would be pretty easy to put a few over the front and you would be very very wet.
Nice wide gunwales.
Probably great for kids on a good day, and miserable on a bad one.
535:
Way more boat. 6.5m on the trailer so won't fit in a standard garage.
Relatively low gunwales at 640mm for a boat this size.
Comparable tow/handling weight to the 1550 and 495 at 750kg BMT, I imagine it would go ok with a 60 but better with a 70+hp motor, especially if you want to tow a ski biscuit or anything like that.
EDITED TO ADD:
I have only talked about Centre/Side Console boats here, rather than cuddy options. It's a shame that FC no longer seems to make a middle-ground between the 435 and 535 in a CC.
My 2c anyway :)
