At Crownline Spain, we see it often: the \u2018problem\u2019 is not the trailer, but a <strong>misunderstood maximum authorised mass<\/strong> (MAM), an <strong>ignored maximum permissible weight<\/strong> (MPW) or an unevenly distributed load.<\/p>\n\n<p class=\"wp-block-paragraph\">If you are considering a unit that will tow well from day one, you can start by looking at <strong><a href=\"https:\/\/crownlinespain.com\/en\/boats-on-stock\/\">Boats in stock<\/a><\/strong> or <strong><a href=\"https:\/\/crownlinespain.com\/en\/pre-owned-boats\/\">Used boats<\/a><\/strong>; and if you want us to get it ready for you (ball, installation, servicing, tune-up), we can take care of it for you through <strong><a href=\"https:\/\/crownlinespain.com\/en\/services\/\">Services<\/a><\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Licences to drive a boat with a trailer in Spain: B, B96 and B+E<\/h2>\n\n<p class=\"wp-block-paragraph\">The rule of thumb is this: permission depends on the <strong>gross vehicle weight rating<\/strong> (GVWR) of the combination (car + trailer), not on \u2018what you think it weighs today\u2019.<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Category B<\/strong> licence: allows you to tow trailers weighing <strong>up to 750 kg GVW<\/strong>; and in some combinations, trailers weighing more than 750 kg if the combination remains within the limits of the licence itself and what the vehicle is authorised for.<\/li>\n\n\n\n<li><strong>B96<\/strong>: <strong>authorisation<\/strong> to extend the combination up to <strong>4,250 kg GVW<\/strong> (car + trailer).<\/li>\n\n\n\n<li><strong>B+E<\/strong>: allows you to tow a trailer with a <strong>maximum authorised mass of up to 3,500 kg<\/strong> with a towing vehicle authorised for category B (and respecting the limits of the combination).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><strong>Crownline tip (no surprises)<\/strong>: before buying a trailer or choosing a boat, check the <strong>technical specifications of the car<\/strong> (MMR with brakes\/without brakes and maximum mass of the combination) and the <strong>MMA of the trailer<\/strong>. If you like, send us the model of your car + boat and we will help you to fit the combination from <strong><a href=\"https:\/\/crownlinespain.com\/en\/contact\/\">Contact<\/a><\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Weights that really matter: MMA, MMR, and \u2018real weight\u2019 (what you carry with you)<\/h2>\n\n<p class=\"wp-block-paragraph\">If you only take one idea away with you, let it be this: <strong>legality can be verified in the documentation (MMA\/MMR), safety can be verified in the actual weight and distribution.<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>MMA (Maximum Authorised Mass)<\/strong>: the legal maximum for each vehicle (car and trailer).<\/li>\n\n\n\n<li><strong>MMR (Maximum Towable Mass)<\/strong> of the car: how much it can tow, normally separated into <strong>braked\/unbraked<\/strong> (technical data sheet information).<\/li>\n\n\n\n<li><strong>Actual transport weight<\/strong>: boat + engine + fuel + batteries + equipment + anchor + refrigerator + awnings + toys +&#8230; (this adds up to more than it seems).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Whether buying new or second-hand, it is very useful to plan your \u2018trailer package\u2019 from the outset. If you are choosing a unit, you can start by <strong><a href=\"https:\/\/crownlinespain.com\/en\/buy-a-new-boat\/\">buying a new boat<\/a><\/strong> (if you want to customise it) or look for opportunities in <strong><a href=\"https:\/\/crownlinespain.com\/en\/pre-owned-boats\/\">second-hand boats<\/a><\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Trailer registration, insurance and MOT: the key cut-off point is 750 kg<\/h2>\n\n<p class=\"wp-block-paragraph\">In Spain, the typical threshold is <strong>750 kg of MMA<\/strong>:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>For trailers with a maximum authorised mass (MAM) of <strong>over 750 kg<\/strong>, the General Vehicle Regulations stipulate that a <strong>number plate must be displayed<\/strong>.<\/li>\n\n\n\n<li>In the case of \u2018light\u2019 trailers (\u2264 750 kg GVW), the DGT explains that they <strong>do not require separate registration<\/strong> in certain cases (and details the approach for caravans\/light trailers).<\/li>\n\n\n\n<li>Regarding <strong>MOT<\/strong>, the casuistry depends on the category and MMA; as a practical guideline, many technical guides distinguish between O1 trailers (\u2264750) and above, with periodic inspections where applicable.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">If you would like us to leave it \u2018closed\u2019 (documentation, installation, inspection of lights, rollers, winch, etc.), we can look into it from <strong><a href=\"https:\/\/crownlinespain.com\/en\/services\/\">Services<\/a><\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Maximum speeds with trailers in Spain (what is often forgotten)<\/h2>\n\n<p class=\"wp-block-paragraph\"><strong>Cars with trailers<\/strong> have specific limits. The official magazine of the DGT (Spanish Traffic Authority) summarises it as follows:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>90 km\/h<\/strong> on <strong>motorways\/dual carriageways<\/strong><\/li>\n\n\n\n<li><strong>80 km\/h<\/strong> on <strong>conventional roads<\/strong><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">This, in addition to legality, is stability: from a certain point onwards, the sway increases dramatically.<\/p>\n\n<h2 class=\"wp-block-heading\">Best practices for transporting a boat (what makes the difference)<\/h2>\n\n<h3 class=\"wp-block-heading\">Load distribution and \u2018ball weight\u2019<\/h3>\n\n<p class=\"wp-block-paragraph\">Stability starts here. Poor distribution causes swaying, poorer braking and damage to tyres\/bearings. As a technical reference, in centre-axle trailers, the relevant regulations limit the vertical load on the coupling to specific maximum percentages.<br\/>In practice: <strong>do not carry the bow too far back<\/strong> or concentrate the weight at the stern; and avoid travelling with tanks \u2018half full\u2019 if this causes liquid displacement.<\/p>\n\n<h3 class=\"wp-block-heading\">Securing the boat: fewer ropes, more judgement<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Ratchet straps at stern (both sides) + bow strap\/lock to winch.<\/li>\n\n\n\n<li><strong>The winch strap is not the only safety device<\/strong>: add a redundant bow sling\/safety device.<\/li>\n\n\n\n<li>Protects gelcoat where straps (covers or protectors) rest.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">Lights, connection, and 30-second checklist<\/h3>\n\n<p class=\"wp-block-paragraph\">Before setting off: indicators, brakes, position, fog lights if applicable, secure connector, visible number plate, tyre pressure, spare wheel, jack\/wrench, and a check of bearings\/temperature at the first stop.<\/p>\n\n<h3 class=\"wp-block-heading\">Driving: anticipation and manoeuvring<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Greater safety distance and progressive braking.<\/li>\n\n\n\n<li>Avoid sudden turns: correct gently.<\/li>\n\n\n\n<li>On ramps, <strong>lock the wheels securely<\/strong>, use wheel chocks if necessary, and do not force the clutch.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">If you want more practical guides on navigation, maintenance and \u2018real life\u2019 with boats, you will find many resources in <strong><a href=\"https:\/\/crownlinespain.com\/en\/news\/\">News<\/a><\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Quick checklist to find out if you can tow your boat with your car<\/h2>\n\n<ol class=\"wp-block-list\">\n<li>Check the <strong>MMR<\/strong> (with brake) on the car&#8217;s specifications sheet.<\/li>\n\n\n\n<li>Check the trailer&#8217;s <strong>MMA<\/strong>.<\/li>\n\n\n\n<li>Estimate the <strong>actual weight<\/strong> of the loaded vessel (including equipment).<\/li>\n\n\n\n<li>Confirm which licence you require: <strong>B \/ B96 \/ B+E<\/strong>.<\/li>\n\n\n\n<li>Check whether your trailer requires its <strong>own registration<\/strong> (&gt;750 MMA).<\/li>\n<\/ol>\n\n<p class=\"wp-block-paragraph\">If you tell us the model of your car, boat and trailer (or the type of boat you are considering), we will get back to you in 1\u20132 messages via <strong><a href=\"https:\/\/crownlinespain.com\/en\/contact\/\">Contact<\/a><\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n<h3 class=\"wp-block-heading\">Can I tow a boat with a B licence?<\/h3>\n\n<p class=\"wp-block-paragraph\">Yes, in many cases.
