Hydrofoils on large capacity outboards vs trim tabs

[Jarrad stevenson]

Hi, have a 6.2m Baysport with factory pod and 175hp G2 Evinrude. Its super practical does the job but obviously doesn’t handle outside like my previous Haines, but it was always a compromise I was happy to walk in to. I think it has a 20 degree deadrise at the rear, progressively softens from front to back.

Anyway I think it could benefit from Trim Tabs (or maybe a wedge) to help soften the ride a little outside however not to the extent that I’m wanting to spend that sort of money. My deckie believes a hydrofoil would help by giving the stern extra lift however never really seen larger hp outboards with a hydrofoil. Boats not underpowered at all so that’s not what we are trying to solve.

Anyone have any experience with them for 150hp+ and if so did you see benefit?

I personally am not a fan of hydrofoils. If a boat is set up right, they only help with getting on the plane quicker.
They can be dangerous as in pulling the stern down and having a wave push the stern around.
Trim tabs are better imo.
That's just my experiences though.

Have put permatrims on quite a few boats, one on a 200hp yammie. All have done what they said they would to a certain extent. But, trim tabs are so much better its not funny. Some kits can be had for $1000, so for the difference just put them on in the first place.

I dont think you can ever go wrong with adding trim tabs but I think those older Baysports were a bit like the Yaltas in that they do bang a bit in the chop....

In terms of purely ride quality are you a bit disappointed in comparison to your previous Haines Hunters..?

[Jarrad stevenson]

On pure ride quality I’d say yes, disappointed compared to the 4 Haines I had prior to this boat.
Overall however going from my last Haines (v17c) to the 620 is the best move I’ve ever made and don’t regret it, and as I said I knew the ride wouldn’t be the same despite it being bigger. More fishing space, more storage space, flexible seating options for family days, more mod cons and better ability to sleep onboard. I’ve even had the wife suggest taking the boat out now.

Would have cost me double for a Haines equivalent to the Baysport which wasn’t feasible so I’ve learned to be patient and drive a bit more sensibly outside - I think my crew have actually enjoyed, certainly less bitching and moaning

trimmed out running in through bars hydrofoils can grab and dive. Depending on the hull and the wave it can be either a nuisance or death defying.

yeah mate when you constricted by budget a boat will always be a compromise..

The narrow beam and steep deadrise of the v17 certainly gives a sweet ride but not nearly so family friendly as something like your new rig..

There is not much you can do about you hull shape but you can can take a bit of that jarring out by installing some suspension..

My boat has 24 degree deadrise but the shockie takes the ride to a new level particularly as we are running 60-80 kms each way..

The trim tabs also really help if your boat tends to lean when you are running into a quartering sea which creates extra pounding in the bow area..
