I got a little 14 foot fiber glass tri hull that I run around the bays here on the otegon coast, mainly Yaquina bay in newport. 20hp mercury tiller dies pretty good, I got to the Jetty all the time with it, maybe 100 yards from open water. Usually by mid afternoon winds pick up and I head in closer the bay cause the swell picks up and tosses me around. I see people in 12 foot v hills actually go out in the ocean to fish the yaquina reef, no thanks. But I do wish to find out what the max swell a tri hull like mine can handle. Anyone got any experiance with a shirt tri hull?

I have no experience with tri hulls, but if you don't feel safe trust your instincts. Going into wide open ocean waters in a 12ft boat is asking for trouble.

Sorta' doesn't work that way. What your boat can handle and what you can handle may or may not match up. The skipper plays a big role in keeping the boat in tough conditions. The other portion of it is intervals. Your boat can handle bigger swells at longer intervals. Shorter intervals, and your boat will have trouble with smaller swells.

A 14' boat with seven foot tall swells at 15 minute intervals (made up numbers) might do okay. That same boat in three foot swells in 20 second intervals might get kinda' sticky.

I can't say never go out like that in a 14' boat as I went 10 miles off shore from Gulfport, MS to the barrier islands on a regular basis with a 13' Taylor Craft, mono hull and 22 hp Scott Atwater engine. Couple of things to note were that the boat had a good Flare to the bow meaning that when the bow went into a wave it had something to push against the water and keep the bow above the wave, and it had a fore deck and windshield which, when I hit that inevitable rogue wave (on the windy return trip....wind directly behind me) and some of it came over the bow, the windshield kept it out of the boat....a seldom occurrence.

Second the trip was directly into or away from the prevailing wind. Going out in the mornings, the wind was usually low and ground swells were long and small. The little 22 was well suited for the trip. Once on the leeward side of the island, wind and waves were blocked. On the return trip in the afternoon, the swells were quite large and I had to ride wave to wave with the boat on one crest just to dive into the trough preceding the next one .....but the flared bow made that a nice, soft, dry, ride.

I had 2 trihulls back in the early 70's and they were noted for their stability, volume efficiency, and dry ride. One was light and semi-v more or less type and the other was heavy and deep V type, 16 and 18'. I would not have taken either out where I took the 13' .
