A number of the big Offshore 125 diving charter boats operating out of Weymouth and Protector now have vertical lifts for divers laden down with 4 cylinders etc. that must be close to 30 stone. Ofcourse if they hadn't eaten so many pies and been the gym occasionaly then they could clime over the tubes without deflating them

the lifts that are on the links are stand up ones i am looking for full 6ft lift. the reason i wanted 30 stone is so there can be a crew member with the diver as he comes into the rib. not because they are all like friar tuck is that a protector looks abit more commercial then the normal one http://www.protectorribs.com/protector/ . sure its not the name of the rib ?

Protector is the name of the rib, think its a Halmatic 28, but does have twin diesels with shafts after I had to cut the shot line off one when a former owner ran over his own shot.

what is the halmatic hull like? they look nice, this is the sort of rib that i will be building. i would move the cabine more to the aft then on this one. the commercial ribs all seem to be built out of aluminum, do you now how the ribs handle this? i was on a yacht and the thing was like a sieve, since then i cant understand why people build with aluminum. if you can fiberglass proberly then it should be just as strong.

The rib has had a cabin change since I last dived from her and now sports a bow cabin rather than the centre cabin, but she is a big steady boat and made a good dive platform for a dozen divers and there kit. Since its difficult to dive in anything above a force 5 we wouldn't normally go to sea above this, however Del Connelly who used to own her thoguht she was superb on the few occasions he got caught out at sea. Don't know what size the tubes are but they must be 26 - 30" in diameter, each section having a separate second tube inside.

she would look better with a center cabin. how meny does she seat? thats a good idea i shall try and get my tubes done like that. we are in process of drawing up some plans for a 10m rib with a wheel house and seating for 6 with jets. have you used hamilton jets in a bigger rib? have you ever used the american jets? what do divers look for in a rib? what makes it easier to get in and out of the water for divers? after speaking with PADI we have come up with a bathing platform that will submerge fully under the water to get divers with the benz and back injuries onboard in the best way. the nearest decompressure chamber is at 20-30 min flight from are operating area. how much will the center wheel house effect the ease of the helicopter pick up?

thanks for the help

Nah, it was a shambles with a centre cockpit, with half the divers up front and the rest at the back it was a nightmare to brief them. Cold up the front in winter too. Finally fumes would draw back across the rear deck at speed from the exhausts because of the aero dynamics of the cabin. A front cabin in this country keeps the spray and cold off the divers when making long trips offshore.

No, but Stu (Rogue wave) has a big one in his rib, have a chat to him.

what do divers look for in a rib?
In this country, somewhere to get out of the cold and a skipper that can make a good brew take a look at this boat, it suits 12 divers with twin sets and side cylinders very well.

A decent diving ladder you can climb with your fins and kit on, wide cut out in the transom and lots of hand holds.

PADI (Put Another Dollar In) don't do deco diving so why would they get the bends okay we won't go there but the divers we have had miss stops etc have surfaced got back on the boat and then we put them on 02 etc. Whilst a full length lift would be nice, is there room on a transom and at what cost ? you will need to think how they get in the water too, without getting in the way of the lift.

when i talked to PADI dive center in paihia new zealand that run trips to rainbow warrior. they said to me that there has been 10 - 12 divers with bends in the last two years in the bay area. i am just building the boat for the purpose of rescue i am not a diver or a medic like my brother and therefore only ask for advice. on the price of building a moving platform its not that hard or that expensive as i can make this with ease myself, however i am open to all advice as i am sure you know alot about diving and can advise me on what is useful! what do you think is the best way to store tanks?

I think Peters boat Trojan in the link is pretty much how I would want to see a dive boat for the UK. The cylinders store on the seats tied up against the gunnels and dive bags under the seats. Large deck area also useful. However it would be worth looking at the dive boats in the area you intend to operate there are often some good reasons for there choice of vessel. Do include a toilet in the plans somewhere though a "bucket and chuck it" isn't really acceptable nowadays.

i have had a good snoop around them. they all have the tanks in the hull but they carry alot of tanks, we only want them for the divers that are on standby in this area for emergencies. they dont have heads except on 3 of them, in the plans of the rib where the v-berth would be is a shower in its own room with the heads (not that big though). any other idears thanks for the help
