We've been experimenting with loading up with lots of media /dive gear for a potential project we've got coming up. We'd need to carry a lot of spare dive gear for a series of dives.
The Ocean is a heavy old lump of a boat and not a fast hull by any means, but she achieves 40 knotts with the 150 Opti running a 19 prop.....more than enough for us!
Have run previously with heavy kit (media divers) and 6 up and whilst not spritely, have achieve around 27 knotts....happy with that too.....
For the project we would potentially need to be loaded up for 4 dives (Everyone diving twinsets) with 6 divers and 1 or poss. 2 crew.....so lots of kit, additional air etc....lots of big blokes too....we'd also be carrying additional fuel (over the 32 gallons in board).
Having loaded up with the same sort of weight we went for a trail run, but just couldn't get the boat to plane properly no matter where the weight was distributed and made around 12 knotts and max 3,500rpm.....time to rethink!
So, am i simply asking too much from the 150 Opti? OR might I have more joy if i try another (which?) prop specifically for when we are running with such heavy gear OR is there something else I could try....I don't want to run overweight /dangerously, but the sponsons were only just resting in the water at rest (usually float above), so confident the hull wasn't overloaded.....no need for great speed, but planeing would be nice
Not sure if it's relevant but the Transom is rated for max OB of 225....at this rate think we're going to need a second boat....
Any advice from divers /those in the know appreciated
