The GP21 is close to a Sea Ark. About the same weight and shape than a Sea Ark of the same size. I tried to replicate their ruggedness.

Which boat is the more ready for the gulf also was thinking about the scaled Ob19 to a Ob21 any input would be appreciated thanks !
Thanks for your input I will pick the GP21 they also remind me of the aluminum Sea Ark which is a great boat in my opinion has anyone built a GP21 yet?
For what it’s worth I don’t think the GP21, with only 3 degrees of deadrise at the transom, will meet your expectations!

I’m curious, when you say use the boat offshore, what does that mean?

How far, how many people, what use, what Sea states?

The reason I ask is that I use my 18 ft 9” flat skiff for everything inside of two miles from the beach. I wouldn’t take it to the nearshore reefs even though I’ve seen other boats that are smaller and with flat bottoms out there before. If I’m going more than 2 miles offshore I take my deep V 24ft walk around.

When you mention offshore rigs, I imagine oil rigs many miles offshore in the Gulf of Mexico.

Because experience tells me that in anything other than light chop it will be rough, slow and wet!

Salty,

Why not use your c17 and see how it does in your sea conditions going out to the rigs. Experience on the open ocean is something which needs to be listened to. The guys from Australia know a lot about big seas.

I fished in a tournament in Tangaloma where they cancelled the tournament one day due to big seas. We had come down from Hong Kong so we went fishing that day anyway. The sea was 18 ft that day and another big sport fisherman vessel out there that day would disappear from view when we were in the valley of the waves. We had a good day fishing and we had a quad hookup of sails but 3 broke off and we tagged one of the four. I never felt unsafe but being in a 40 foot deep v sport fisherman with a very experience skipper makes a lot of difference.

Experience, experience, my friend.

Regards
Tom

Here in Louisiana we have rigs right of the coast i would only go on calm days and want to be able to take 4-5 ppl comfortably

I was planning on give my dad the c17 he really like it i can see the glow in his eyes while we are building it so i know i need another boat for myself so if im going to build another one may as well be bigger right but im only able to get away with building up to a 21-22 footer due to space and i would really be pushing my build space with anything bigger than that

I only would go out on calm days thats why i wanted something versatile that can do both inshore and offshore an carry a 4-5crew probably would be doing more inshore tho but would still like to venture offshore few miles sometimes if i wanted

There is no doubt that a deeper vee will handle better once the sea builds up, no miracle there but if offshore means in good weather and close to a safe harbor only, the GP21 will be fine.
