The boats are usually relatively small so they can easily be transported on roads and launched at a convenient site depending on the weather. Boats of this size can be launched from slipways or through the surf on suitable beaches. The smaller models are suitable for private use, as they can only transport a few divers. The larger boats can carry enough divers to be viable for professional use. These boats will generally carry basic safety equipment such as marine VHF radio, small boat safety gear, lifejackets and first aid oxygen administration equipment.<sup id="cite_ref-DSP_guide_1-1" class="reference"><a href="#cite_note-DSP_guide-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>Space in the boat is limited, and divers generally travel and kit up while sitting on the tubes opposite a central cylinder rack where the fully rigged scuba sets are stowed. Water entry is commonly by simultaneous rolling backwards over the side, and return to the boat by climbing back in over the tubes one at a time after removing the heavy parts of the <a href="/wiki/Diving_equipment" title="Diving equipment">diving equipment</a> and handing it up to the crew. Some boats have ladders which hook over the tubes to make boarding easier for the less athletic diver, others rely on assistance from the crew. An advantage of this type of boat compared with similar-sized rigid boats is that the inflated tubes make the boat very stable during the entry and exit of the divers and if the boat is filled with water during surf transit maneuvers. These boats are usually fairly fast, maneuverable, seaworthy in surf and rough conditions, and relatively wet and uncomfortable. They seldom provide any shelter from the elements, and their advantages are that they get the diver to the site and back fairly quickly, are generally good for operation through surf, are usually trailerable and can be launched at slipways and beaches.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

Day boats are generally relatively large: typically, between 60 and 90 feet (18 and 27 m) in length, as they must provide some comfort for the passengers for several hours. Many day boats are used for scuba-divers and also for other marine tourism activities such as fishing and whale-watching. In general, divers or passengers will spend only the daylight hours on a day boat, and do not sleep in them overnight. Dive boats which provide sleeping accommodation are generally referred to as "liveaboard" boats. Generally a professional crew operate the boat. The boat provides shelter from the weather and is likely to have various facilities such as a toilet (called the "head") and a small kitchen (called a "galley"), to cater for the guests and crew. Day-boats may have a saloon where divers can relax on upholstered benches, and one or more dining tables. Many day boats also have an uncovered sun-deck, and a shaded area, for divers wishing to be out in the open air. The boat will usually have a diving air compressor, oxygen first aid, a VHF radio, a GPS and possibly gas blending facilities. A day boat would generally be used to transport divers to multiple dive-sites (typically between one and three sites) during the same day, or multiple dives at the same site, with surface rest and refreshment periods between them.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

The lift mechanism constrains sideways motions of the platform, and has sufficient hand-holds for the diver to stand securely during lifting. A lift may also be used to lower a diver into the water. In most cases the lift will be suitable for transporting a fully kitted diver in a standing position, but in special cases seating may be provided. It differs from a diving stage or basket, which is lowered to diving depth, as a lift generally can only be lowered deep enough to stand up after swimming over the platform, which for most divers will be between 1 and 1.5 metres (3.3 and 4.9 ft).<sup id="cite_ref-Knight_2019_9-0" class="reference"><a href="#cite_note-Knight_2019-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> The lifting platform should have enough space to stand wearing fins, and there should be suitable handholds to allow the diver to be stable during lifting and lowering with a low risk of getting equipment or body parts in pinch points. The space allowed for walking between platform and boat should take into account the equipment likely to be carried by the diver, such as side mounted cylinders. </p> <div class="mw-heading mw-heading2"><h2 id="Dive_boat_operations">Dive boat operations</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Dive_boat&action=edit&section=15" title="Edit section: Dive boat operations"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Procedures for diving from a boat vary depending on the boat, the diving equipment, the dive site and the dive plan.<sup id="cite_ref-NOAA_Diving_Manual_1979_10-0" class="reference"><a href="#cite_note-NOAA_Diving_Manual_1979-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Stowage_of_dive_gear">Stowage of dive gear</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Dive_boat&action=edit&section=16" title="Edit section: Stowage of dive gear"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Trim and stability of small boats can be significantly influenced by where and how the dive gear is stowed.

Some skippers will tether the tender behind the dive boat where it can also be used as a drift line.<sup id="cite_ref-Jeppesen_1993_2-5" class="reference"><a href="#cite_note-Jeppesen_1993-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> A lazy shot or decompression trapeze may be suspended from the boat near the boarding area, and the drift line may be set up between this and the anchor line to guide decompressing divers ascending on the anchor line to the more convenient facility at the stern for the shallow stops. </p> <div class="mw-heading mw-heading4"><h4 id="Live-boating">Live-boating</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Dive_boat&action=edit&section=27" title="Edit section: Live-boating"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><span title="See entry on this page at § Live-boating" class="glossary-link-internal" style="border-bottom: 1px dashed #86a1ff; color:initial;"><a href="/wiki/Glossary_of_underwater_diving_terminology:_H%E2%80%93O#Live-boating" title="Glossary of underwater diving terminology: H–O">Live-boating</a></span> is diving from a boat which is not moored.<sup id="cite_ref-NOAA_Diving_Manual_1979_10-2" class="reference"><a href="#cite_note-NOAA_Diving_Manual_1979-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup><sup class="reference nowrap"><span title="Page / location: 13–7">: 13–7 </span></sup> There are increased risks due to the proximity of the divers to propellers when the engines are running, but there are also safety and convenience advantages to having the boat available to move at immediate notice, particularly in currents, as the boat can follow a group of drift divers, and pick up the divers from where they surface in most cases.

There are several methods for getting the divers to the wreck. The preferred method will depend on local conditions. In low visibility hooking onto the wreck is a reliable way of ensuring the divers will find it, but this procedure requires a wreck that is structurally suitable for snagging with a <a href="/wiki/Grapnel" class="mw-redirect" title="Grapnel">grapnel</a> or <a href="/wiki/Anchor" title="Anchor">anchor</a>. A <a href="/wiki/Shotline" class="mw-redirect" title="Shotline">shotline</a> which can be dropped off the wreckage is less likely to damage the wreck or become snagged and difficult to retrieve, but this requires appropriate visibility for the divers to be sure of finding the wreckage. When it is important to get back to the shotline for ascent, it may be tied to the wreckage by the first divers on site using a guide-line, which is retrieved by the last divers to leave. When there is a strong current, it may be necessary to drop in from up-current, a technique sometimes known as "parachuting in" or "free drop". The wreck may be first marked with a shotline, if this is considered useful or necessary. Divers may surface on the shotline, anchorline or personal <a href="/wiki/Decompression_buoy" class="mw-redirect" title="Decompression buoy">DSMB</a> depending on the conditions.<sup id="cite_ref-Dituri_2008_23-0" class="reference"><a href="#cite_note-Dituri_2008-23"><span class="cite-bracket">[</span>23<span class="cite-bracket">]</span></a></sup> When <span title="See entry on this page at § live-boating" class="glossary-link-internal" style="border-bottom: 1px dashed #86a1ff; color:initial;"><a href="/wiki/Glossary_of_underwater_diving_terminology:_H%E2%80%93O#live-boating" title="Glossary of underwater diving terminology: H–O">live-boating</a></span> there are alternative methods for descent, including free drop and descent on the shotline.<sup id="cite_ref-Citelli_2008_21-1" class="reference"><a href="#cite_note-Citelli_2008-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> </p><p>An <span title="See entry on this page at § upline" class="glossary-link-internal" style="border-bottom: 1px dashed #86a1ff; color:initial;"><a href="/wiki/Glossary_of_underwater_diving_terminology:_T%E2%80%93Z#upline" title="Glossary of underwater diving terminology: T–Z">upline</a></span>(or Jersey upline) may be used to limit drift during ascent. This is a fairly substantial natural fibre rope which is deployed from the bottom using a small lift bag to provide the equivalent of a shotline. The lower end is tied off to the bottom, usually on a wreck, and the diver ascends on the line to avoid being swept away from the site by currents.
